OpenStreetMap in GIScience – Experiences, Research, and Applications

OSM in GIScience

A new book has just been published about OpenStreetMap and Geographic Information Science. The book, which was edited by Jamal Jokar Arsanjani, Alexander Zipf, Peter Mooney, Marco Helbich  is “OpenStreetMap in GISciene : Experiences, Research, and applications” contains 16 chapters on different aspects of OpenStreetMap in GIScience including 1) Data Management and Quality, 2) Social Context, 3) Network Modeling and Routing, and 4) Land Management and Urban Form.

I’ve contributed a preface to the book, titled “OpenStreetMap Studies and Volunteered Geographical Information” which, unlike the rest of the book, is accessible freely.

Crowdsourced Geographic Information in Government

Today marks the publication of the report ‘crowdsourced geographic information in government‘. ReportThe report is the result of a collaboration that started in the autumn of last year, when the World Bank Global Facility for Disaster Reduction and Recovery(GFDRR)  requested to carry out a study of the way crowdsourced geographic information is used by governments. The identification of barriers and success factors were especially needed, since GFDRR invest in projects across the world that use crowdsourced geographic information to help in disaster preparedness, through activities such as the Open Data for Resilience Initiative. By providing an overview of factors that can help those that implement such projects, either in governments or in the World Bank, we can increase the chances of successful implementations. To develop the ideas of the project, Robert Soden (GFDRR) and I run a short workshop during State of the Map 2013 in Birmingham, which helped in shaping the details of project plan as well as some preliminary information gathering. The project team included myself, Vyron Antoniou, Sofia Basiouka, and Robert Soden (GFDRR). Later on, Peter Mooney (NUIM) and Jamal Jokar (Heidelberg) volunteered to help us – demonstrating the value in research networks such as COST ENERGIC which linked us.

The general methodology that we decided to use is the identification of case studies from across the world, at different scales of government (national, regional, local) and domains (emergency, environmental monitoring, education). We expected that with a large group of case studies, it will be possible to analyse common patterns and hopefully reach conclusions that can assist future projects. In addition, this will also be able to identify common barriers and challenges.

We have paid special attention to information flows between the public and the government, looking at cases where the government absorbed information that provided by the public, and also cases where two-way communication happened.

Originally, we were aiming to ‘crowdsource’  the collection of the case studies. We identified the information that is needed for the analysis by using  few case studies that we knew about, and constructing the way in which they will be represented in the final report. After constructing these ‘seed’ case study, we aimed to open the questionnaire to other people who will submit case studies. Unfortunately, the development of a case study proved to be too much effort, and we received only a small number of submissions through the website. However, throughout the study we continued to look out for cases and get all the information so we can compile them. By the end of April 2014 we have identified about 35 cases, but found clear and useful information only for 29 (which are all described in the report).  The cases range from basic mapping to citizen science. The analysis workshop was especially interesting, as it was carried out over a long Skype call, with members of the team in Germany, Greece, UK, Ireland and US (Colorado) while working together using Google Docs collaborative editing functionality. This approach proved successful and allowed us to complete the report.

Wilson Center talk – Environmental Information: The Roles of Experts and the Public

On 29th April, I gave a talk in the Wilson Center in Washington DC on ‘Environmental Information – the Roles of Experts and the Public. The event was organised by Lea Shanley, who is heading the ‘Commons Lab‘ initiative of the center, and Dr Jay Benforado, from the US Environment Protection Agency (EPA) provided a response to the talk.

The talk is based on a forthcoming chapter in a book that will be the final output of the EveryAware project, and I can share a copy of it if you email me.

I described the content of the talk as:  ‘Access to environmental information and use of it for environmental decision-making are central pillars of environmental democracy. Yet, not much attention is paid to the question of who is producing it, and for whom? By examining the history of environmental information, since NEPA in 1969, three eras can be identified: information produced by experts, for experts (1969-1992); information produced by experts, to be shared by experts and the public (1992-2012); and finally, information produced by experts and the public to be shared by experts and the public.

Underlying these are changes in access to information, rise in levels of education and rapid change due to digital technologies. The three eras and their implication to environmental decision-making will be explored, with special attention to the role of geographical information systems and to citizen science.’

The talk (and the chapter) are building on the themes that I discussed in a presentation during the Eye on Earth user conference in Dublin in 2013, and earlier talks in Oxford Transport Studies UnitUCL Centre for Advanced Spatial Analysis and at University College Dublin School of Geography, Planning & Environmental Policy in 2010 (see also my reflection from the Eye on Earth summit in Abu Dhabi in 2011). In the talk I covered some of the legal frameworks about production and use of environmental information, including laws and international agreements, as well as using specific demonstrations of the information systems themselves, as to demonstrate the practice. I also tried to suggest the trends that are behind the changes in the eras, and levels of education is quite central.

On reflection, the 4 years that passed since I started thinking about the ‘eras of environmental information‘ allowed me to think how to communicate them, and I hope for the better. It also made the writing up of the chapter easier, as the responses and comments that I received in previous talks provided the needed feedback and peer review to structure the text.

Although I was setting specific dates as markers for the eras, the reality is that the boundaries are more flexible and the transition was over time – it is especially difficult for the latest transition of public participation in environmental information production.

The talk was followed by a discussion that lasted almost 45 minutes, and during the discussion, the common issue of data quality of citizen science data or the interesting point about the issue of dissemination as Rob Baker noted: ‘Is the role of experts as facilitators extend to dissemination of information or just collection? Who closes the loop? ‘  (https://twitter.com/rrbaker/statuses/461157624592203776) or Susan Wolfinbarger question about citizen science: ‘How do you know when the quality of a #citsci project is bad?’  (https://twitter.com/SWolfinbarger/statuses/461166886043262976)

The presentation and discussion were captured on YouTube, below

GIS chapter in ‘Introducing Human Geographies’

There is something in the physical presence of book that is pleasurable. Receiving the copy of Introducing Human Geographies was special, as I have contributed a chapter about Geographic Information Systems to the ‘cartographies’ section.

It might be a response to Ron Johnston critique of Human Geography textbooks or a decision by the editors to extend the content of the book, but the book now contains three chapters that deal with maps and GIS. The contributions are the ‘Power of maps’ by Jeremy Crampton, a chapter about ‘Geographical information systems’ by me, and ‘Counter geographies’ by Wen Lin. To some extent, we’ve coordinated the writing, as this is a textbook for undergraduates in geography and we wanted to have a coherent message.

Overall, you’ll notice a lot of references to participatory and collaborative mapping, with OpenStreetMap and PPGIS.net mentioned several times.

In my chapter I have covered both the quantitative/spatial science face of GIS, as well as the critical/participatory one. As the introduction to the section describes:

“Chapter 14 focuses on the place of Geographical Information Systems (GIS) within contemporary mapping. A GIS involves the representation of geographies in digital computers. … GIS is now a widespread and varied form of mapping, both within the academy and beyond. In the chapter, he speaks to that variety by considering the use of GIS both within practices such as location planning, where it is underpinned by the intellectual paradigm of spatial science and quantitative data, and within emergent fields of ‘critical’ and ‘qualitative GIS’, where GIS could be focused on representing the experiences of marginalized groups of people, for example. Generally, Muki argues against the equation of GIS with only one sort of Human Geography, showing how it can be used as a technology within various kinds of research. More specifically, his account shows how current work is pursuing those options through careful consideration of both the wider issues of power and representation present in mapping and the detailed, technical and scientific challenges within GIS development.”

UCL Urban laboratory pamphleteer – Beyond Quantification: We Need Meaningful Smart Cities

The UCL Urban Laboratory is a cross-disciplinary initiative that links various research interest in urban issues, from infrastructure to the way they are expressed in art, films and photography. The Urban Laboratory has just published its first Urban Pamphleteer which aim to ‘confront key contemporary urban questions from diverse perspectives. Written in a direct and accessible tone, the intention of these pamphlets is to draw on the history of radical pamphleteering to stimulate debate and instigate change.’

http://www.ucl.ac.uk/urbanlab/news/UrbanPamphleteer_1

My contribution to the first pamphleteer, which focused on ‘Future & Smart Cities’ is dealing with the balance between technology companies, engineers and scientists and the values, needs and wishes of the wider society. In particular, I suggest the potential of citizen science in opening up some of the black boxes of smart cities to wider societal control.  Here are the opening and the closing paragraphs of my text, titled Beyond quantification: we need a meaningful smart city:

‘When approaching the issue of Smart Cities, there is a need to discuss the underlying assumptions at the basis of Smart Cities and challenge the prevailing thought that only efficiency and productivity are the most important values. We need to ensure that human and environmental values are taken into account in the design and implementation of systems that will influence the way cities operate…

…Although these Citizen Science approaches can potentially develop new avenues for discussing alternatives to the efficiency and productivity logic of Smart Cities, we cannot absolve those with most resources and knowledge from responsibility. There is an urgent need to ensure that the development and use of the Smart Cities technologies that are created is open to democratic and societal control, and that they are not being developed only because the technologists and scientists think that they are possible.’

The pamphleteer is not too long – 32 pages – and include many thought-provoking pieces from researchers in Geography, Environmental Engineering, Architecture, Computer Science and Art. It can be downloaded here.

GeoHCI 2013 – Geography meet Human-Computer Interaction

CHI (Computer-Human Interaction) is the premier conference in the calendar of Human-Computer Interaction (HCI) studies. While the first paper that deal with geographic technologies within this conference was presented in 1991 (it was about User Interfaces for Geographic Information Systems by Andrew Frank and presented at a special interest group meeting), geography did not received much attention from HCI researchers in general, though the growth of location-based technologies made it a growing area in recent years. As I noted elsewhere, HCI did received interest in GIScience over the years, with more attention paid to spatial cognition and fundamental aspects of knowledge representation but unfortunately less on interaction design and exploration of user studies.

This sort of loose coupling between GIScience and HCI is also reflected in personal histories.  I was aware of CHI and its importance for over 15 years, but I never managed to attend one – until now. When Brent Hecht invited me to join a CHI workshop proposal on Geographic HCI (GeoHCI), I jumped on the opportunity. The process of working together with HCI researchers on coordinating and curating a workshop led to mutual learning about priorities and practices of work of the two different research communities – in the tone and style of position papers, reviews and ways of organising a meeting. The response to the call for position papers was overwhelming and demonstrated the interest from both geography and HCI communities to find opportunities to converse and share ideas.

The workshop itself was excellent, with coverage of many topics that are being actively researched in Geography and GIScience – and the papers and presentation cover crowdsourced/volunteered geographic information, use of geographic information in crisis situations, participatory mapping and citizen science, concepts of place and space, personal memories, and of course many interactions with maps.

My own talk focused on Geography and HCI, exploring the point of view of geography when approaching computing environments to represent and communicate geographical knowledge. I have used human geography and particularly the concept of space/place to highlight the contribution that geography can make. For example in understanding the multiplicity of interpretation of place by using both David Harvey critique of spatial sciences in the understanding of place, and Doreen Massey relational geography description of places as ‘stories so far’ in ‘For Space‘ as a clear example of different conceptualisation of what they are.

One particular point that I highlighted, following the first chapter of Introducing Human Geographies in which a differentiation is made between Geography as ‘writing the Earth': looking at human-nature relationship in the wider sense, versus ‘writing the World’ : looking at society-space relationships. For HCI audience I described it by rephrasing Don Norman’s differentiation between ‘Geography in the world‘ which is about the way people interact with the physical environment around them, versus ‘Geography in the head‘ which is the cultural, personal and social understanding of the place where they are and how they want to shape their personal activities, memories and interactions. Of course, Geography in the world is easier to represent in computers then the Geography in the head, and my personal view is that too much emphasis is paid to the first type.

Another part of the presentation focused on the importance of Cartography for geographical technologies, and why issues of map scale, media and task context are very important when designing geographic applications. For example, the value of paper as a media and understanding that maps are more about context then about ‘you are here’.

My position paper is available here . My presentation is provided below

In my view, the workshop was very valuable in opening new conversations. I have now a better understanding of the context in which HCI researchers in Google, Yahoo! and Pitney-Bowes Business Insight consider geography and what problems they have. The issue of place and the need to explore platial information came up several times, and we also experienced the multi-sensory engagement with place which are difficult to capture in digital forms. Most importantly, this was an experience in understanding the language and ways of expression that can help in bridging the two communities.

Transactions of the Institute of British Geographers virtual issue on GIScience

Since early 2010, I had the privilege of being a member of the editorial board of the journal Transactions of the Institute of British Geographers . It is a fascinating position, as the journal covers a wide range of topics in geography, and is also recognised as one of the top journals in the field and therefore the submissions are usually of high quality. Over the past 3 years, I was following a range of papers that deal with various aspects of Geographic Information Science (GIScience) from submission to publication either as a reviewer or as associate editor. Transactions of the IBG cover

In early 2011, I agreed to coordinate a virtual issue on GIScience.  The virtual issue is a collection of papers from the archives of the journal, demonstrating the breadth of coverage and the development of GIScience within the discipline of geography over the years. The virtual issues provide free access to a group of papers for a period of a year, so they can be used for teaching and research.

Editing the virtual issue was a very interesting task – I was exploring the archives of the journal, going back to papers that appeared in the 1950s and 1960s. When looking for papers that are relevant to GIScience, I came across various papers that relate to geography’s ‘Quantitative Revolution‘. The evolution of use of computers in geography and later on the applications of GIS is covered in many papers, so the selection was a challenge. Luckily, another member of the editorial board, Brian Lees, is also well versed in GIScience as the editor of the International Journal of GIScience. Together, we made the selection of the papers that are included in the issue. Other papers are not part of the virtual issue but are valuable further reading.

To accompany the virtual issue, I have written a short piece, focusing on the nature of GIScience in geography. The piece is titled “Geographic Information Science: tribe, badge and sub-discipline” and is exploring how the latest developments in technology and practice are integrated and resisted by the core group of people who are active GIScience researchers in geography.

You can access the virtual issue on Wiley-Blackwell online library and you will find papers from 1965 to today, with links to further papers that are relevant but not free for access. The list of authors is impressive, including many names that are associated with the development of GIScience over the years from Torstan Hägerstrand or David Rhind to current researchers such as Sarah Elwood, Agnieszka Leszczynski or  Matt Zook.

The virtual issue will be officially launched (and was timed to coincide with) at the GIScience 2012 conference.

As I cannot attend the conference, and as my paper mentioned the Twitter-based GeoWebChat (see http://mappingmashups.net/geowebchat/) which is coordinated by Alan McConchie, I am planning to use this medium for running a #geowebchat that is dedicated to the virtual issue on the 18th September 2012, at 4pm EDT, 9pm BST so those who attend the conference can join at the end of the workshops day.
