UCL Institute for Global Prosperity Talk: Extreme Citizen Science – Current Developments

The slides below are from a talk that I gave today at UCL Institute for Global Prosperity

The abstract for the talk is:

With a growing emphasis on civil society-led change in diverse disciplines, from International Development to Town Planning, there is an increasing demand to understand how institutions might work with the public effectively and fairly.

Extreme Citizen Science is a situated, bottom-up practice that takes into account local needs, practices and culture and works with broad networks of people to design and build new devices and knowledge creation processes that can transform the world.

In this talk, I discussed the work of UCL Extreme Citizen Science group within the wider context of the developments in the field of citizen science. I covered the work that ExCiteS has already done, currently developing and plans for the future.

Environmental information: between scarcity/abundance and emotions/rationality

The Eye on Earth Summit, which was held in Abu Dhabi last week, allowed me to immerse myself in the topics that I’ve been researching for a long time: geographic information, public access to environmental information, participation, citizen science, and the role of all these in policy making. My notes (day 1 morning, day 1 afternoon, day 2 morning, day 2 afternoon, day 3 morning & day 3 afternoon) provide the background for this post, as well as the blog posts from Elisabeth Tyson (day 1, day 2) and the IISD reports and bulletins from the summit. The first Eye on Earth Summit provided me with plenty to think about, so I thought that it is worth reflecting on my ‘Take home’ messages.

What follows are my personal reflections from the summit and the themes that I feel are emerging in the area of environmental information today. 

wpid-wp-1444166132788.jpgWhen considering the recent ratification of the Sustainable Development Goals or SDGs by the UN Assembly, it is not surprising that they loomed large over the summit – as drivers for environmental information demand for the next 15 years, as focal points for the effort of coordination of information collection and dissemination, but also as an opportunity to make new links between environment and health, or promoting environmental democracy (access to information, participation in decision making, and access to justice). It seems that the SDGs are very much in the front of the mind of the international organisations who are part of the Eye on Earth alliance, although other organisations, companies and researchers who are coming with more technical focus (e.g. Big Data or Remote Sensing) are less aware of them – at least in terms of referring to them in their presentations during the summit.

Beyond the SDGs, two overarching tensions emerged throughout the presentations and discussions – and both are challenging. They are the tensions between abundance and scarcity, and between emotions and rationality. Let’s look at them in turn.

Abundance and scarcity came up again and agin. On the data side, the themes of ‘data revolution’, more satellite information, crowdsourcing from many thousands of weather observers and the creation of more sources of information (e.g. Environmental Democracy Index) are all examples for abundance in the amount of available data and information. At the same time, this was contrasted with the scarcity in the real world (e.g species extinction, health of mangroves), scarcity of actionable knowledge, and scarcity with ecologists with computing skills. Some speakers oscillated between these two ends within few slides or even in the same one. There wasn’t an easy resolution for this tension, and both ends were presented as challenges.


With emotions and scientific rationality, the story was different. Here the conference was packed with examples that we’re (finally!) moving away from a simplistic ‘information deficit model‘ that emphasise scientific rationality as the main way to lead a change in policy or public understanding of environmental change. Throughout the summit presenters emphasised the role of mass media communication, art (including live painting development through the summit by GRID-Arendal team), music, visualisation, and story telling as vital ingredients that make information and knowledge relevant and actionable. Instead of a ‘Two Cultures’ position, Eye on Earth offered a much more harmonious and collaborative linkage between these two ways of thinking and feeling.

Next, and linked to the issue of abundance and scarcity are costs and funding. Many talks demonstrated the value of open data and the need to provide open, free and accessible information if we want to see environmental information used effectively. Moreover, providing the information with the ability of analyse or visualise it over the web was offered as a way to make it more powerful. However, the systems are costly, and although the assessment of the IUCN demonstrated that the investment in environmental datasets is modest compared to other sources (and the same is true for citizen science), there are no sustainable, consistent and appropriate funding mechanisms, yet. Funding infrastructure or networking activities is also challenging, as funders accept the value, but are not willing to fund them in a sustainable way. More generally, there is an issue about the need to fund ecological and environmental studies – it seem that while ‘established science’ is busy with ‘Big Science’ – satellites, Big Data, complex computer modelling – the work of studying ecosystems in an holistic way is left to small group of dedicated researchers and to volunteers. The urgency ad speed of environmental change demand better funding for these areas and activities.

This lead us to the issue of Citizen Science, for which the good news are that it was mentioned throughout the summit, gaining more prominence than 4 years ago in the first summit (were it also received attention). In all plenary sessions, citizen science or corwdsourced geographic information were mentioned at least once, and frequently by several speakers. Example include Hermes project for recording ocean temperatures, Airscapes Singapore for urban air quality monitoring, the Weather Underground of sharing weather information, Humanitarian OpenStreetMap Team work in Malawi, Kathmandu Living Lab response to the earthquake in Nepal, Arab Youth Climate Movement in Bahrain use of iNaturalist to record ecological observations, Jacky Judas work with volunteers to monitor dragonflies in Wadi Wurayah National Park  – and many more. Also the summit outcomes document is clear:  “The Summit highlighted the role of citizen science groups in supporting governments to fill data gaps, particularly across the environmental and social dimensions of sustainable development. Citizen Science was a major focus area within the Summit agenda and there was general consensus that reporting against SDGs must include citizen science data. To this end, a global coalition of citizen science groups will be established by the relevant actors and the Eye on Earth Alliance will continue to engage citizen science groups so that new data can be generated in areas where gaps are evident. The importance of citizen engagement in decision-making processes was also highlighted. ”

However, there was ambivalence about it – should it be seen as an instrument, a tool to produce environmental information or as a mean to get wider awareness and engagement by informed citizens? How best to achieve the multiple goals of citizen science: raising awareness, educating, providing skills well beyond the specific topic of the project, and democratising decision making and participation? It seem to still be the case that the integration of citizen science into day to day operations is challenging for many of the international organisations that are involved in the Eye on Earth alliance.

Another area of challenging interactions emerged from the need for wide partnerships between governments, international organisations, Non-Governmental Organisations (NGOs), companies, start-ups, and even ad-hoc crowds that respond to a specific event or an issue which are afforded by digital and social network. There are very different speeds in implementation and delivery between these bodies, and in some cases there are chasms that need to be explored – for example, an undercurrent from some technology startups is that governments are irrelevant and in some forms of thinking that ‘to move fast and break things’ – including existing social contracts and practices – is OK. It was somewhat surprising to hear speakers praising Uber or AirBnB, especially when they came from people who familiar with the need for careful negotiations that take into account wider goals and objectives. I can see the wish to move things faster – but to what risks to we bring by breaking things?

With the discussions about Rio Principle 10 and the new developments in Latin America, the Environmental Democracy Index, and the rest, I became more convinced, as I’ve noted in 2011, that we need to start thinking about adding another right to the three that are included in it (access to environmental information, participation in decision-making, and access to justice), and develop a right to produce environmental information that will be taken seriously by the authorities – in other words, a right for citizen science. I was somewhat surprised by the responses when I raised this point during the discussion on Principle 10.

Final panel (source: IISD)

Finally, Eye on Earth was inclusive and collaborative, and it was a pleasure to see how open people were to discuss issues and explore new connections, points of view or new ways of thinking about issues. A special point that raised several positive responses was the gender representation in such high level international conference with a fairly technical focus (see the image of the closing panel). The composition of the speakers in the summit, and the fact that it was possible to have such level of women representation was fantastic to experience (making one of the male-only panels on the last day odd!). It is also an important lesson for many academic conferences – if Eye on Earth can, I cannot see a reason why it is not possible elsewhere.

Esri survey123 tool – rapid prototyping geographical citizen science tool

There are several applications that allow creating forms rapidly – such as Open Data Kit (ODK) or EpiCollect. Now, there is another offering from Esri, in the form of Survey123 app – which is explained in the video below.

Survey123 is integrated into ArcGIS Online, so you need an ArcGIS account to use it (you can have a short experiment if you register for a trial account, but for a longer project you’ll have to pay). The forms are configured in XForms, like ODK . The forms can be designed in Excel fairly quickly, and the desktop connection package make it easy to link to the Survey123 site, as well as testing forms.  I tried creating a form for local data collection, including recording a location and taking an image with the phone. It was fairly easy to create forms with textual, numerical, image and location information, and the software also supports the use of images to items in the form, so they can be illustrated visually. The desktop connector application also allow use to render the form, so they can be tested before they are uploaded to ArcGIS Online. Then it is possible to distribute the form to mobile devices and use them to collect the information.

The app works well offline, and it is possible to collect multiple forms and then upload them all together. While the application still showing rough edges in terms of interaction design, meaningful messages and bug clearing, it can be useful for developing prototypes and forms when the geographic aspect of the data collection is central. For example, during data collection the application supports both capturing the location from GPS and pointing on a map to the location where the data was collected. You can only use GPS when you are offline, as for now it doesn’t let you cache a map of a study area.

As might be expected, the advantage of Survey123 is coming once you’ve got the information and want to analyse it, since ArcGIS Online provide the tools for detailed GIS analysis, or you can link to it from a desktop GIS and analyse and visualise the information.

Luckily for us, Esri is a partner of the Extreme Citizen Science group and UCL also holds an institutional licence for ArcGIS Online, so we have access to these tools. However, through Esri conservation programme can also apply to have access to ArcGIS Online and use this tool.

Life on Mars – new blog on citizen science and interaction


Jess Wardlaw, who have just completed her PhD at the Extreme Citizen Science group has started blogging about her new project which involves imagery of Mars, citizen science and studies of interaction. Her blog can be found at https://thegeographigal.wordpress.com/2015/05/26/life-on-mars/ and the post below.

It’s now a week since my viva, which flouted all my expectations in every possible way. I could not have prepared myself for so many of the questions I was asked or being so lost for words. I will forever be grateful to my examiners for reading my thesis and their suggestions/corrections; as its writer I often felt like I was stirring a sauce that would never thicken. Now that it’s thickened I can have some fun over the summer with the flavouring as I work through the corrections they gave me. My arms might ache like crazy from all the stirring but I can finally say that I’m just a few seasonings short of being able to let other people eat it and move on to making the next course.

By this I mean my new project. So far I have really enjoyed immersing myself in fresh literature (recommendations will be forthcoming) and playing…

AAG 2015 notes – day 4 – Citizen Science & OpenStreetMap Studies

The last day of AAG 2015 is about citizen science and OpenStreetMap studies.

The session Beyond motivation? Understanding enthusiasm in citizen science and volunteered geographic information was organised together with Hilary Geoghegan. We were interest to ‘explore and debate current research and practice moving beyond motivation, to consider the associated enthusiasm, materials and meanings of participating in citizen science and VGI.’

As Hilary couldn’t attend the conference, we started the session with a discussion about experiences of enthusiasm – for example, my own experience with IBM World Community Grid.  Jeroen Verplanke raised the addiction in volunteer thinking projects, such as logging in to Zooniverse or Tomnod project, and time fly-by. Mairead de Roiste described mapping wood-pigeon in New Zealand – public got involved because they wanted to help, but when they hear that the data wasn’t use, they might lose interest. Urgency can also be a form influencing participation.

Britta Ricker – University of Washington Tacoma – Look what I can do! Harnessing drone enthusiasm for increased motivation to participate. On-going research. Looking at the Geoweb – it allow people to access information, and made imagery available to the public, and the data is at the whim of whoever give us the data. With drones, we can send them up when we want or need to. Citizen Science is deeply related to geoweb – challenge is to get people involve and make them stay involved. We can harness drone enthusiasm – they evoke negative connotation but also thinking about them for good – humanitarian applications. Evidence for the enthusiasm is provided by YouTube where there are plenty of drone video – 3.44M – lots of action photography: surfing community and GoPro development. People are attached to the drone – jumping to the water to save them. So how the enthusiasm to drones can be harnessed to help participatory mapping. We need to design a workflow around stages: pre-flight, flight, post processing. She partnered with water scientists to explore local issues. There are considerations of costs and popularity – and selected quadcopter for that. DJI Phantom Vision 2+. With drones need to read the manual and plan the flight. There are legal issues of where it is OK to fly, and Esri & MapBox provide information on where you can fly them. Need to think of camera angle – need also to correct fisheye, and then process the images. Stitch imagery can be done manually (MapKnitter/QGIS/ArcGIS). Possible to do it in automated software, but open source (e.g. OpenDroneMap) is not yet good enough in terms of ease of use. Software such as Pix4D is useful but expensive. Working with raster data is difficult, drones require practice, and software/hardware is epensive – not yet ready to everyone. NGOs can start using it. Idea: sharing photos , classifying images together by volunteers.

Brittany Davis – Allegheny College – Motivated to Kill: Lionfish Derbies, Scuba Divers, and Citizen Science. Lionfish are stunning under water – challenging to differentiate between the two sub species but it doesn’t matter if you’re trying to catch them. They are invasive species and are without predators, exploded – especially from 2010. There is a lot of informational campaign and encouraging people to hunt them, especially in dive centres – telling people that it is a way to save a Caribbean reefs. When people transform themselves from ‘benign environmental activity’ to ‘you tell me that I can hunt? cool!’. Lionfish is tasty so having the meat for dinner is a motivation. Then doing ‘lionfish derbies’ – how many can you kill in a day. Seen a lot of enthusiasm for lionfish derbies. Trying to sign up people to where they go but they are not recording where they hunt the lionfish. People go to another site for competition as they want to capture more. REEF trying to encourage a protocol for capturing them, and there are cash prizes for the hunting. They use the catch to encourage people to hunt lionfish. Derbies increase in size – 14832 were removed from 2009 to 2014 and some evidence for the success of the methodology. There was a pressure on ‘safely and humanely capture and euthanase these fish’ – challenge for PADI who run special scuba courses that are linked to conservation. People hear about the hunting and that motivate people to go diving. There is a very specific process of REEF sanctioned lionfish derby, so trying to include recording and public information. But there are challenges below the depth of recreational divers. She also explored if it is possible to improve data collection for scientists.

Cheryl Gilge – University of Washington – The rhetorical flourish of citizen participation (or, the formation of cultural fascism?) offered a theoretical analysis of citizen science and web 2.0 as part of a wider project to understand labour relationships and power. She argues that there is agency to the average citizen to link to their environment. They have the ability to contribute, and to receive information is part of Web 2.0. As a technology layer, it changes both the individual and society levels. The collaboration and participation in Web 2.0 is framed around entrepreneurialism, efficiencies, and innovation. The web is offering many opportunities to help wider projects, where amateur and expert knowledge are both valued. However, there is a risk of reducing the politics of participation – semblance of agency. Democratic potential – but also co-opting the spirit is in evidence. There is plenty of examples of inducing individuals to contribute data and information, researchers are eager to understand motivation over a long period. Rational system to explain what is going on can’t explain the competing goals and values that are in action. The desire to participation is spread – fun, boredom etc. From understanding people as ‘snowflakes’ to unashamed exploitation. Why do people contribute to the wider agenda? As provocation, harnessing crowd potential to neoliberalisation agenda of universities. We give freedom to the efficiency and promise of digital tools. Government promise ‘open government’ or ‘smart cities’ that put efficiency as the top value. Deep libertarian desire for small government is expressed through technology. The government have sensors that reduce cost of monitoring what is happening. In the academic environment – reduce funding, hiring freeze, increase in pressure to publish – an assumption that it is possible to mechanically produce top research. Trading in ideas are less valued. Desire for capacity of information processing, or dealing with humanitarian efforts – projects like Galaxy Zoo require more people to analyse the masses of data that research produces, or mapathons to deal with emergencies. Participants are induced to do more through commitment to the project and harnessing enthusiasm. Adding inducement to the participants. She introduce the concept of micro-fascism from Guattari  – taking over freedoms in the hope of future promises. It enable large group formation to happen – e.g. identities such as I’m Mac/PC – it is harder to disconnect. Fascism can be defined as an ideology that rely on the masses in believing in the larger goals, the unquestioned authority of data in Web 2.0. Belief in technology induce researchers to get data and participation regardless of the costs. Open source is presented as democracy, but there are also similarities with fascism. Participation in the movement and participants must continue to perform. It bring uncomfortable participation – putting hope on these activities, but also happens in top down and bottom up, and Web 2.0. What is the ethical role of researchers who are involved in these projects? How do we value this labour? Need to admit that it is a political.

In a final comment, Teresa Scassa pointed that we need to consider the implication of legitimising drones, killing fish or employing unpaid labour – underlying all is a moral discomfort.

Afternoon, the two sessions on OpenStreetMap that Alan McConchie and I organised, taking the 10th birthday of OSM as a starting point, this session will survey the state of geographical research on OpenStreetMap and recognising that OSM studies are different from VGI. The session is supported by the European COST Energic (COST Action IC1203) network: European Network Exploring Research into Geospatial Information Crowdsourcing.

OpenStreetMap Studies 1 

Jennings Anderson, Robert Soden, Mikel Maron, Marina Kogan & Ken Anderson – University of Colorado, Boulder – The Social Life of OpenStreetMap: What Can We Know from the Data? New Tools and Approaches. OSM provides a platform to understand human centred computing. The is very valuable information in OSM history file, and they built a framework (EPIC OSM) that can run spatial and temporal queries and produces JSON output that can be then analysed. They are use existing tools and software frameworks to deliver it. The framework was demonstrated: can ask questions by day, or by month and even bin them by week and other ways. Running such questions which are evaluated by Ruby, so easy to add more questions and change them. They already use the framework in a paper in CHI about the Haiti earthquake (see video below).  Once they’ve created the underlying framework, they also developed an interface – OSM Markdown – can embed code and see changesets, accumulative nodes collected and classification by type of user. They are also providing information with tags. When analysing Haiti response, they see spike in noted added and what they see in buildings – the tags of collapse=yes

Christian Bittner – Diverse crowds, diverse VGI? Comparing OSM and Wikimapia in JerusalemChristian looked at differences in Wikimapia and OSM as sources of VGI. Especially interested in the social implications such as the way exclusion plays in VGI – challenges between Palestine/Israel – too contradicting stories that play out in a contested space, and there are conflict and fights over narratives that the two sides enact in different areas. With new tools, there is a ‘promise’ of democratisation – so a narrative of collaboration and participation. In crowdsourced geographic information we can ask: who is the crowd, and who is not? Studying social bias in OSM is a topic that is being discussed in the literature. The process is to look at the database of OSM. Analysing the data and metadata and used the municipal boundaries of Jerusalem. Simplified representation of the city, and region are classified by majority – Arab or Jewish. Then used cartograpms according to size of population and the amount of information collected.In OSM, Jewish areas are over-represented, while Arab areas are under-represented. Bias toward male from privileged socio-economic background as participants. In Wikimapia, the process is tagging places and uses visual information from Google. Wikimapia is about qualitative information so objects are messy and overlap, with no definitions of what consist of a place. In Wikimapia, there is much more descriptions of the Arab areas which are over-represented. The amount of information in Wikimpaia is smaller – 2679 objects, compared to 33,411 ways in OSM. In OSM there is little Arabic, and more Hebrew, though Latin is the most used language. Wikimapia is the other way around, with Hebrew in the minority. The crowd is different between projects. There are wider implications – diverse crowd so diverse VGI? VGI is diverse form of data, and they are produced in different ways from different knowledge cultures. He call for very specific studies on each community before claiming that VGI is general form of information.

Tim Elrick  & Georg Glasze – University of Erlangen-Nuremberg, Germany –  A changing mapping practices? Representation of Places of Worship in OpenStreetMap and other sourcesThe start of the process is noticing that churches are presented on official maps, but not a masques, noticing how maps are used to produce specific narratives. What happen in new forms of mapping? In Google Maps, the masque is presented, but not the church, in OSM both are mapped. What is happening? In the old topographic maps, the official NMAs argue that it provides a precise representation – but failing to do so in terms of religious differences. Some state do not include non-Christian places of worship – the federal mapping agency came with symbols for such places (masques, synagogues) but the preference from the states NMAs was for a generic mark for all non-Christian places that do not differentiate between religions. USGS just have single mark for house of worship – with cross. The USGS suggested to carry out crowdsourcing to identify places of worship so they are willing to change. In OSM there are free tagging and marks for religion, but the rendering dictate only some tags. In 2007 there was suggestion to change rendering of non-Christian places. Once Steve Chilton created cartographic symbols for the change. OSM do-ocracy can lead to change, but in other places that use OSM this was not accepted – there are different symbols in OpenCycleMaps. In Germany, there are conflicts about non visible places of worship (e.g. Masque in social club). Adaptive approach to dealing with location in OSM. In Google there is a whole set of data sources that are used, but also crowdsourcing which go to moderators in Google – no accountability or local knolwedge. Places of worship is not transparent. Categorisation and presentation change with new actors – corporate and open data. Google use economy of attention.

Alan McConchie – University of British Columbia – Map Gardening in Practice: Tracing Patterns of Growth and Maintenance in OpenStreetMap. Looking at history of OSM. Editing existing features is an important as adding new ones – having to collaborate and dealing with other people data. In the US, OSM is a mixed of volunteer and imported data – it’s ongoing aspect of the project. Questions: do the ‘explorers’ stick around? the people who like empty spaces . Do imports hinder the growth of the community? and does activity shift to ‘gardening’? The TIGER import in 2007 have been significant to the growth of the project. There are also many other imports – address in Denmark, French land cover, incomplete land cover imports in Canada. There was community backlash from people who were concerned about the impact of imports (e.g. Crowe 2011; Fredrik Ramm, 2012, Tobias Knerr, 2015). The debate is also between different regional factions. There is an assumption that only empty areas are exciting. That is problematic in terms of someone joining now in Germany. New best practices that are evolving Imports in Seattle were used to encourage the community and build it. Zielstra et al. 2013 explored imports show different growths, but not so simple as just to pin it on imports. Alan takes the ‘Wiki Gardening’ concept – people who like to keep things tidy and well maintained. Analysing small areas. Identifying blank spots, but trying to normalise across city in the world – e.g. population from the gridded population of the world. Exploring edits per month. We see many imports happening all the time. At individual city, explore the behaviour of explorers and those that never mapped the unknown. In London, new mappers are coming in while at Vancouver the original mapper are the one that continue to maintain the map. There is power law effects that trump anything else, and shift to new contributors and it is not clear cut.

Monica G. Stephens – University at Buffalo – Discussant: she started looking at OSM only few years ago, because of a statement from Mike Goodchild that women are not included, so done survey of internet users in Google Maps and OSM. She found that geotagging is much more male – more then just sharing image. In her survey she noticed gender bias in OSM. Maps are biased by the norms, traditions, assumptions and politics of map maker (Harley 1989). Biases – but biases of map maker – bikes in Denver (what interest them), or uneven representation of Hebrew in Jerusalem, or Religious attributes. Also there is how the community makes decision – how to display information? what to import? There are issues of ethos – there are fundamental differences in UK and Germany communities to US mapping communities. This lead to interesting conversations between these communities. There are also comparison, Wikimapia, Google Maps, Topo Maps – the tell us what OSM is doing. OSM democracy is more efficient and responding to communities ideas. The discussions on tagging childcare – rejected but there are discussions that led to remapping of tags in response to the critique. Compare to Google Maps, who was creating local knowledge? in Google Maps 96% of reviewers are male (in Google Map Maker 2012), so the question is who is the authority that govern Wikimapia.

OpenStreetMap Studies 2  included the following:

Martin Loidl – Department of Geoinformatics, University of Salzburg – An intrinsic approach for the detection and correction of attributive inconsistencies and semantic heterogeneity in OSM data. Martin come from data modelling perspective, accepting that OSM is based on bottom-up approach, with flat data modelling and attributes, with no restriction on tag usage. There are attributive inconsistencies. Semantics heterogeneity is influencing visualisation, statistics and spatial analysis. Suggesting to improve results by harmonization and correction through estimation. There has been many comparison of OSM quality over the years. There is little work on attribute information. Martin suggested an intrinsic approach that rely on the data in OSM – expecting major roads to be connected and consistent. Showing how you can attributes in completeness. Most of the road in OSM are local roads and  and there is high heterogeneity, but we need them and we should care about them. There are issues with keeping the freedom to tag – it expose the complexity of OSM.

Peter A. Johnson – University of Waterloo Challenges and Constraints to Municipal Government Adoption of OpenStreetMap. The collaboration of MapBox with NYC – agreement on data sharing was his starting point and motivation to explore how we can connect government and citizens to share data. Potentially, OSM community will help with official data, improve it and send it back. Just delivering municipal data over OSM base map is not much – maybe we need to look at mirroring – questions about currency, improvement of our services, and cheaper/easier to get are core questions. Evaluating official data and OSM data. Interview with governments in Canada, with range of sizes – easy in large cities, basic steps in medium and little progress in rural places. No official use of OSM, but do make data available to OSM community, and anecdotal evidence of using it for different jobs unofficially. Not seeing benefits in mirroring data, and they are the authoritative source for information, no other data is relevant. Constraints: not sure that OSM is more accurate and risk averse culture. They question fit with organisation needs, lacking required attributes, and they do see costs in altering existing data. OSM might be relevant to rural and small cities where data is not being updated.

Muki Haklay – University College London COST Energic – A European Network for research of VGI: the role of OSM/VGI/Citizen Science definitionsI’ve used some of the concepts that I first presented in SOTM 2011 in Vienna, and extended them to the general area of citizen science and VGI. Arguing that academics need to be ‘critical friends’, in a nice way, to OSM and other communities. The different talks and Monica points about changes in tagging demonstrate that this approach is effective and helpful.

Discussant: Alan McConchie – University of British Columbia. The later session looked at intrinsic or extrinsic analysis of OSM – such as Martin’s work on internal consistency, there are issues of knowing specific person in the bits of the process who can lead to the change. There is a very tiny group of people that make the decisions, but there is a slow opening towards accountability (e.g. OSM rendering style on Github). There are translation of knowledge and representation that happen in different groups and identifying how to make the information correctly. There is a sense of ‘no one got the right answer’. Industry and NGOs also need to act as critical friends – it will make it a better project. There is also critical GIS conversations – is there ‘fork’ within the OSM studies? We can have conversations about these issues.

Follow up questions explored the privacy of the participants and maybe mentioned it to participants and the community, and also the position as participant or someone who alters the data and as a researcher – the implications of participatory observations.

GISRUK 2015 papers: participatory mapping in Nairobi and mobile apps for Earthquake and Fire

The GIS Research UK conferences (GISRUK) are the annual gathering of the GIScience research community in the UK. While I have missed the last two (including the current one in Leeds), I have contributed to two papers that are presented in the conference.

The first, ‘Participatory mapping for transformation: multiple visual representation of foodscapes and environment in informal settlements in Nairobi‘ was led by Sohel Ahmed , and include myself, Adriana Allen (UCL DPU), Cecilia Tacoli (IIED) , Edwin Simiyu (SDI) and Julio Davila (UCL DPU). It was written on the basis of the work that was carried out in the Urban Zoo project and explores participatory mapping with food vendors. The summary of this short paper note that ‘although branded as ‘obstructionists’ and major agents of ‘disease and filth’ by city authorities, food vendors remain the pivotal node in the local food system in most informal settlements; therefore, their interaction with the environment and infrastructure services, and challenges they face to keep the food safe to eat, requires further grounded exploration. Food vendors from informal settlements in Nairobi, Kenya, who are acting as mappers and change agents, are building multi-layered views of places through the deliberative process of knowledge co-production by participatory sensing, which lead to opportunities and challenges to improve those places.’. The paper is accessible here. See also Cecilia and Sohel blog post and briefing paper on their work in Nairobi

The second, ‘Exploring new ways of digital engagement: a study on how mobile mapping and applications can contribute to disaster preparedness‘ is written by Gretchen Fagg, Enrica Verrucci, and Patrick Rickles as part of the Challenging Risk project. The paper looks at mobile applications that can be used to help people prepare for natural disasters. The abstract note that ‘natural disasters can happen at any time and no community can consider itself completely safe from them. Digital technologies, such as Geographic Information Systems (GIS), are becoming globally pervasive (World Bank, 2014), with smartphones hosting excellent mobile mapping, data collection and information providing platforms. A report was compiled to investigate web and mobile applications that provide preparedness information and stimulate community empowerment, some using maps as a medium to convey the information. This paper discusses the purpose, results and implications of this analysis for further work to be undertaken to address the identified research gap.’ The paper is available here.

New paper: Footprints in the sky – using student track logs in Google Earth to enhance learning

screen shot for paperIn 2011-2012, together with Richard Treves, I was awarded a Google Faculty Research Award, and we were lucky to work with Paolo Battino for about a year, exploring how to use Google Earth tours for educational aims. The details of the projects and some reports from the project are available on Richard’s blog, who was leading on many aspects of the work. Now, over 2 years since the end of the project, we have a publication in the Journal of Geography in Higher Education. The paper, titled ‘Footprints in the sky: using student track logs from a “bird’s eye view” virtual field trip to enhance learning’, is now out and describes the methodology that we developed for tracking students’ actions.

The abstract of the paper is:

Research into virtual field trips (VFTs) started in the 1990s but, only recently, the maturing technology of devices and networks has made them viable options for educational settings. By considering an experiment, the learning benefits of logging the movement of students within a VFT are shown. The data are visualized by two techniques: “animated path maps” are dynamic animations of students’ movement in a VFT; “paint spray maps” show where students concentrated their visual attention and are static. A technique for producing these visualizations is described and the educational use of tracking data in VFTs is critically discussed.
