Remote Sensing in Ecology and Conservation is a new open access journal, addressing the interdisciplinary field that links different aspects of remote sensing (the use of different imaging and sensing technologies) and the field of ecology and conservation. It is publishing its papers in Open Access, so the papers are free to download and share.

With the encouragement of the journal editorial team, a group of editors (Helen Roy, Tom August, Linda See, Tanya Berger-Wolf & myself) set out a call for a special issue on citizen science. Citizen science is becoming part of the way research in ecology and conservation is now carried out, and there are plenty of examples of the use of remote sensing techniques – from the Do-It-Yourself balloon mapping that you see above, as part of research that explores how human, livestock, and food is linked to an informal settlement in Nairobi, to use of drones by non-professional researchers, to the use of satellite imagery.

One of my favourite citizen science project – PenguinWatch – is an example for remote sensing, as it uses camera traps imagery that is then uploaded to the Zooniverse platforms, and volunteers help in counting how many penguins appear in the image.

The call text is:

For centuries amateur naturalists have contributed to science; for example, by recording the distribution of species. However, in recent decades, advances in technology have revolutionised “citizen science” and far more people are involved in different ways than was historically the case. We invite high-quality contributions about citizen science to a special issue of Remote Sensing in Ecology and Conservation. The aim is to demonstrate the diversity of citizen science, in terms of approach and research themes, and the contributions of remote-sensing techniques. We are particularly interested in innovative research that identifies the intersection between remote sensing and citizen science for conservation, such as DIY balloon or kite mapping, the use of photo-sharing apps and the integration of satellite observations with ground truth by volunteers. Papers that reveal how citizen science and remote sensing can be used to monitor Essential Biodiversity Variables (EBVs) are also welcome. The main objective is to describe the breadth and depth of engagement that is now possible using different approaches to citizen science. High-quality submissions for this special issue will be considered on a case-to-case basis for a full fee waiver, where authors are unable to pay the Article Processing Fees.
Submission deadline 15 July 2017.

Paper: GeoKey – open infrastructure for community mapping and science

Citizen Cyberlab The special issue of the Human Computation Journal (see the details of the editorial here), summarises the result from the EU FP7 “Citizen Cyberlab” project.

One of the outcomes of the project is the development of the GeoKey platform for participatory mapping. Therefore, a paper that was written with Oliver Roick and Claire Ellul explains the background to the system and its design principles.

The abstract is:

The development of the geospatial web (GeoWeb) over the past decade opened up opportunities for collaborative mapping and large scale data collection at unprecedented scales. Projects such as OpenStreetMap, which engage hundreds of thousands of volunteers in different aspects of mapping physical and human-made objects, to eBird, which records millions of bird observations from across the globe. While these collaborative mapping efforts are impressive in their scale and reach, there is another type of mapping which is localised, frequently carried out over a limited period of time, and aims at solving a specific issue that the people who are living in the locality are facing. These needs are addressed in participatory mapping, which nowadays includes citizen science elements in data collection and management. The paper describes the background and design of a novel infrastructure for participatory mapping and science – GeoKey. The paper provides a differentiation between collaborative and participatory mapping, describes the state of the art and several usecases of community mapping, and the architecture of GeoKey, focussing both on the approaches to data capture and subsequent potential to share the data in an open manner where possible. It also describes the design elements that support learning and creativity in these projects.

The paper is open access and free to read, and you can find it at

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 ‘local spatial knowledge’, 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 ‘elite capture’ and manipulation. Another challenge to the PGIS ‘slow, small, and intense’ 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 ‘scientific’.

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 – you 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 – discussing, 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 – there are tangible academic outputs that emerge from such workshops – demonstrating 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) – the 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
