Public Participation GIS and Participatory GIS in the Era of GeoWeb – editorial for a special issue

As part of the AAG 2015 conference, Bandana Kar, Rina Ghose, Renee Sieber and I organised a set of sessions on Public Participation GIS – you can read the summary here.¬†After the conference, we’ve organised a special issue of the Cartographic Journal (thanks to Alex Kent, the journal editor)¬†dedicated to current perspectives of public participation GIS (PPGIS) and participatory GIS (PGIS).

The process of organising a special issue is quite involved – not all the papers that start the journey managed to finish, and even at the last point, 2 papers that are part of the special issue will appear in the next issue of the journal due to physical limitations and the number of pages that appear in each issue!

Working with an editorial group across the US, Canada, and the UK was also a challenge, especially as we were all busy, as usual. Bandana Kar kept us going and because of her continued efforts and encouragement, the special issue was evolving. So it’s only right that she is the lead author of the editorial piece. Our editorial points to the evolution of PPGIS and the need to understand how it is shaped up in the era of web-based mapping and rapid increase in the use of mobile technologies. The papers in the special issue (you can find them here) are addressing this evolving landscape and are all worth reading. We finish our editorial with the following statement:

‘In this sea of changing tools and technologies it appears that P/PGIS may be competing with other approaches and terminologies. At its core many of the new projects remain mission-driven, are led by local residents, and requires generation of data and knowledge to resolve a specific problem. The data generated through platforms old and new still suffer from lack of interoperability and data quality issues. Analytics may have been improved since the days of the command-line but still require considerable expertise; moreover, evidence-based policy, especially from the non-credentialled, must have entree into politics. Moving forward, researchers and practitioners should focus on not answering the place of P/PGIS amid new technologies and approaches but instead examine the extent to which new participatory technologies are effective in integrating local, scientific and personal knowledge in resolving political decisions and societal issues of interest to local communities.’

A Shared Perspective for PGIS and VGI – new paper

Part of the special issue on Public Participation GIS that was published in The Cartographic Journal, was a paper that was led by Jeroen Verplanke (ITC). This paper goes back to the workshop on participatory GIS in 2013, that was the leaving event for Dr Mike McCall in ITC, after which he continue to work in UNAM, Mexico.

Since the symposium in June 2013, we developed the paper, trying to find the path and linkage between the area of Participatory GIS (the variety of Public Participation GIS in development context) and the crowdsourced world of Volunteered Geographic Information.

The paper abstract explains its aims:

“This paper reviews persistent principles of participation processes. On the basis of a review of recent interrogations of the (Public) Participatory Geographic Information Systems (P)PGIS and Volunteered Geographic Information (VGI) approaches, a summary of five prevailing principles in participatory spatial information handling is presented. We investigate these five principles that are common to (P)PGIS and VGI on the basis of a framework of two dimensions that govern the participatory use of spatial information from the perspective of people and society. This framework is presented as a shared perspective of (P)PGIS and VGI and illustrates that, although both share many of these same principles, the ways in which these principles are approached are highly diverse. The paper ends with a future outlook in which we discuss the inter-connected memes of potential technological futures, the signification of localness in ‚Äėlocal spatial knowledge‚Äô, and the ramifications of ethical tenets by which PGIS and VGI can strengthen each other as two sides of the same coin.”

We finish the paper with the following observations: “With the unprecedented growth of data from sensors, including human sensors working through VGI, the main obstacles shaping the access and use of Local Spatial Knowledge (LSK) are the ethics of participatory practices. Greater access to, and supply of, VGI will not improve the depth of knowledge or insight into local contexts, and not necessarily, even the breadth of inputs. It might instead bias LSK identification and flows towards the most active and connected members in the community. This is already a recognized issue with PGIS and other participatory processes which are open to ‚Äėelite capture‚Äô and manipulation. Another challenge to the PGIS ‚Äėslow, small, and intense‚Äô approach comes from the ubiquity of cheap sensors; there is a concern that only evidence backed up with instrumental information (e.g. bodycams providing images with GPS and time stamp) will be considered suitable by higher authority decision-makers. Ethical facilitation is needed to guide the ownership and confidentiality of LSK in a connected world where this knowledge and the metadata of its distribution are increasingly valued (only) for their direct marketing potential. PGIS offers rich, culturally sensitive and situated LSK, and it is essential to maintain the value of this knowledge against the challenge of big data (VGI) being treated as more ‚Äėscientific‚Äô.

New paper: Usability and interaction dimensions of participatory noise and ecological monitoring

The EveryAware book provided an opportunity to communicate the results of a research that Dr Charlene Jennett led, together with two Masters students: Joanne (Jo) Summerfield and Eleonora (Nora) Cognetti, with me as an additional advisor. The research was linked to the EveryAware, since Nora explored the user experience of WideNoise, the citizen science noise monitoring app that was used in the project. There is also a link to the Citizen Cyberlab project, since Jo was looking at the field experience in ecological observation, and in particular during a BioBlitz. The chapter provides a Human-Computer Interaction (HCI) perspective to the way technology is used in citizen science projects. You can download the paper here and the proper citation for the chapter is:

A review of volunteered geographic information quality assessment methods

One of the joys of academic life is the opportunity to participate in summer schools Рyou get a group of researchers, from PhD students to experienced professors, to a nice place in the Italian countryside, and for a week the group focuses on a topic Рdiscussing, demonstrating and trying it out. The Vespucci Institute in 2014 that was dedicated to citizen science and Volunteered Geographic Information (VGI) is an example for that. Such activities are more than a summer retreat Рthere are tangible academic outputs that emerge from such workshops Рdemonstrating that valuable work is done!

During the summer school in 2014, Hansi Senaratne suggested to write a review of VGI data quality approaches, and together with Amin Mobasheri and Ahmed Loai Ali (all PhD students) started to developed it. I and Cristina Capineri, as summer school organisers and the vice-chair & chair of COST ENERGIC network (respectively), gave advice to the group and helped them in developing a paper, aimed at one of the leading journal of Geographic Information Science (GIScience) Рthe International Journal of GIScience (IJGIS).

The paper went through the usual peer review process, and with a huge effort from Hansi, Amin & Ahmed, it gone all the way to¬†publication. It is now out. The paper is titled ‘A review of volunteered geographic information quality assessment methods‘ and is accessible through the journal’s website.¬†The abstract is provided below, and if you want the pre-print version – you can download it from here.

With the ubiquity of advanced web technologies and location-sensing hand held devices, citizens regardless of their knowledge or expertise, are able to produce spatial information. This phenomenon is known as volunteered geographic information (VGI). During the past decade VGI has been used as a data source supporting a wide range of services, such as environmental monitoring, events reporting, human movement analysis, disaster management, etc. However, these volunteer-contributed data also come with varying quality. Reasons for this are: data is produced by heterogeneous contributors, using various technologies and tools, having different level of details and precision, serving heterogeneous purposes, and a lack of gatekeepers. Crowd-sourcing, social, and geographic approaches have been proposed and later followed to develop appropriate methods to assess the quality measures and indicators of VGI. In this article, we review various quality measures and indicators for selected types of VGI and existing quality assessment methods. As an outcome, the article presents a classification of VGI with current methods utilized to assess the quality of selected types of VGI. Through these findings, we introduce data mining as an additional approach for quality handling in VGI

New PhD Opportunity:¬†Human Computer Interaction and Spatial Data Quality for Online Civic Engagement

We have a new scholarship opening at the Extreme Citizen Science group for a PhD student who will research in Human Computer Interaction and Spatial Data Quality for Online Civic Engagement. The studentship is linked and contextualised by the European Union H2020 funded project, WeGovNow! . This project will focus on the use of digital technologies for effectively supporting civic society, whereby citizens are partners as opposed to customers in the delivery of public services. By integrating a set of innovative technologies from different European partners in Germany, Italy, and Greece to create citizen engagement platform, the project explores the use of digital tools for citizen reporting, e-participation, and communication between the citizen and local government. Building on previous research and technology development, the project will include programme of innovation in technology and services delivery. More information on the UCL ExCiteS blog

ECSA annual meeting in Barcelona (28-29 October)

Barcelona is becoming a hub of strong support for Citizen Science with an office for citizen science at the city level. It was therefore the site of the 2015 annual meeting of the European Citizen Science Association.

wpid-wp-1446153439017.jpgOn the day before the annual meeting, the afternoon was dedicated to a citizen science safari, with visit to the Parc de la Ciutadella and the nearby coast, learning and trying a range of citizen science projects.

Some of my notes from the meeting day are provided below.

Katrin Vohland (ECSA vice chair) open with noting that we see growing networks at national levels (Austria, Germany) and internationally. She noted that role of ECSA as a networking organisation and draw parallels to transformative social innovation theory which talks about ‘guided expansion’. ECSA can develop into multiple hubs (innovation, urban, ecology etc.) with shared responsibility and potentially distributed secretariat . We can share experiences and work load across the network and find new ways to grow.

Libby Hepburn (Australian Citizen Science Association ACSA) talked about the experience in Australia from two perspectives ¬†– personally running the Coastal Atlas of Australia and being involved in ACSA. Starting with the Australian context – the history that it didn’t have many people (20 mil population over space larger than Europe, displacement of aboriginal groups and loss of local knowledge) and impact of weather and climate is important. Only 25% of Australian species have been described. There are lots of introduced species – from rabbits to dung beetles to cane toads, thought there are counter examples such as dung beetles are actually successful as they deal with the impact from hoofed species that were introduced. The development of science in Australia is from the late 19th century. ¬†The political approach towards science is complex and changing, but citizen science doesn’t wait for the political environment. The Australian Museum created a project to digitise over 16,000 transcriptions of species. Projects such as Explore the Sea-floor allow people to classify images that are being taken automatically under the sea. Philip Roetman Cat Tracker project is another example, allowing to understand the damage that domestic cats causing to local biodiversity. The atlas of living Australia allow for information sharing and distribution patterns. and additional layers – including likely rainfall. They are starting to develop a citizen science project finder, and starting an association – while keeping links to the other emerging associations and projects. She noted the analysis of the Socientize white paper, OPAL, and other lessons from around the world.

wpid-wp-1446156208999.jpgA presentation from the Citi-Sense project explained the need for development of sensor-based on citizens’ observatory community. Some of the products that are ready for use. Starting to have stationary boxes that are becoming possible to produce information about air quality. They have developed the CityAir app which provide to report geolocated perceptions and visualise user community reports. Provide personal and community perceptions. There are ways of integrating the data from the models and perception.

Sven Schade (JRC) talked about the citizen science data flow survey. Received 149 projects. at different scales –¬†from neighbourhood to multi national. The data re-usability is that while 90 projects provide data, the majority do that after embargo.

Daniel Wyler (University of Z√ľrich) talked about the citizen science in universities – an initiative in the University of Z√ľrich – establish citizen science at public research and education bodies, they want to establish the Z√ľrich Citizen Science Centre, and developing two papers – a policy paper about the area, and a set of suggested standards for research universities and science funding bodies.

Josep Parelló talked about creativity and innovation in Barcelona РBCNLAb is collaboration with the city council Рproviding a hub that allow grass-roots to create activities. Providing open scope Рthey established a citizen science office and promoting participatory practices in scientific research, enjoy from multipliers of research, sharing resources, having a large base of committed participants, common protocol, data repository. He used inspiration from Michel Callon (2003) Research in the wild concept.

Daniel Garcia wpid-wp-1446153467202.jpgtalked about the Responsible Research and Innovation Challenges and the linkage to citizen science. RRI includes concept such as CBPR, Science Shops , Open Science. Citizen Science is concerned in the political acceptance to inform policies. There are multiple links between RRI and Citizen Science.


Anne Bowser and Elisabeth Tyson described the Wilson Center commons lab and the emerging legal landscape in the US:¬†the crowdsourcing and citizen science bill of 2015 that is being offered in congress – it’s about educating policy makers to the topic. There was also memo from the Office of Science and technology Policy. The memo asked to have point of contacts for citizen science, secondly standardising metadata and cataloguing citizen science activities. A toolkit was published to assist with the implementation. There is an effort of creating a shared database across the CSA,, SciStarter and other sources. There is value in these database for end users, and also use the database as a research tools.

From the ECSA meeting itself there are several news: ECSA have 84 members from 22 countries 30% individual members, the rest organisational members. New badge for ECSA Рyou can have a badge that recognise ECSA members. The working group on the principle and standards published the 10 principles of citizen science. The new working group deal with best practice and building capacity. Data working group exploring interoperability, privacy/reliability, and intellectual property rights. The international conference is now in planning in 19-21 May 2016, and there is an emerging social media representation on Instagram and Facebook. The policy group is engaging at EU policy levels, but also noticing international developments in the area of citizen science and policy. Planning policy briefing. Responding to policy consultations, and there are some proposals for  areas that ECSA can impact policy. A new working group was suggested to coordinate the work of citizen science facilitators. New members selected to the advisory board: Malene
Bruun (European Environmental Agency),¬†Alan Irwin (Department of Organization at Copenhagen Business School),¬†Michael¬†S√łgaard J√łrgensen
(DIST, Aalborg University), Roger Owen (Scottish Environment Protection Agency) and Ferdinando Boero (University of Salento).
