The Potential of Volunteered Geographic Information (VGI) in Future Transport Systems

dsc01541An aspect of collaborative projects is that they start slowly, and as they become effective and productive, they reached their end! The COST Energic (European Network for Research into Geographic Information Crowdsourcing) led to many useful activities, with some of them leading to academic papers. From COST Energic, we’ve got the European Handbook on Crowdsourced Geographic Information, a paper on VGI quality assessment methods, and more.

One outcome came out from the close collaboration around the summer schools that were organised by the network. Prof Cristina Capineri was the chair of the COST network, and also the organiser of summer schools in Fiesole, near Florence. Prof Maria Attard organised the other summer school of the action, at the University of Malta. Based on our close working relationships (though Maria and I know each other since our PhD studies in CASA) we started working on a joint paper. Maria specialises in transport geography, so the support from COST Energic was a reason to consider how VGI will play out in future transport systems. The paper was published in the journal Urban Planning and the abstract reads:

“As transport systems are pushed to the limits in many cities, governments have tried to resolve problems of traffic and congestion by increasing capacity. Miller (2013) contends the need to identify new capabilities (instead of capacity) of the transport infrastructure in order to increase efficiency without extending the physical infrastructure. Kenyon and Lyons (2003) identified integrated traveller information as a facilitator for better transport decisions. Today, with further developments in the use of geographic information systems (GIS) and a greater disposition by the public to provide volunteered geographic information (VGI), the potential of information is not only integrated across modes but also user-generated, real-time and available on smartphones anywhere. This geographic information plays today an important role in sectors such as politics, businesses and entertainment, and presumably this would extend to transport in revealing people’s preferences for mobility and therefore be useful for decision-making. The widespread availability of networks and smartphones offer new opportunities supported by apps and crowdsourcing through social media such as the successful traffic and navigation app Waze, car sharing programmes such as Zipcar, and ride sharing systems such as Uber. This study aims to develop insights into the potential of governments to use voluntary (crowdsourced) geographic information effectively to achieve sustainable mobility. A review of the literature and existing technology informs this article. Further research into this area is identified and presented at the end of the paper.”

Published: Why is Participation Inequality Important?

bookcoverI’ve mentioned the European Handbook for Crowdsourced Geographic Information in the last post, and explained how it came about. My contribution to the book is a chapter titled ‘Why is Participation Inequality Important?. The issue of participation inequality, also known as the 90:9:1 rule, or skewed contribution, has captured my interest for a while now. I have also explored it in my talk at the ECSA conference on ‘participatory [citizen] science‘ and elsewhere.

In this fairly short chapter what I am trying to communicate is that while we know that participation inequality is happening and part of crowdsourced information, we need to consider how it influences issues such as data quality, and think how it come about. I am trying to make suggest how we ended with skewed contributions – after all, at the beginnings of most projects, everyone are at the same level – zero contribution, and then participation inequality emerge.

I have used the iconic graph of contribution to OpenStreetMap that Harry Wood created, but the chapter is discussing other projects and activities where you can come across this phenomena.

Here is a direct link to the chapter, and I’ll be very happy to hear comments about it!

 

New book: European Handbook of Crowdsourced Geographic Information

COST EnergicCOST ENERGIC is a network of researchers across Europe (and beyond) that are interested in research crowdsourced geographic information, also known as Volunteered Geographic Information (VGI). The acronym stands for ‘Co-Operation in Science & Technology’ (COST) through ‘European Network Researching Geographic Information Crowdsourcing’ (ENREGIC). I have written about this programme before, through events such as twitter chats, meetings, summer schools and publications. We started our activities in December 2012, and now, 4 years later, the funding is coming to an end.

bookcoverOne of the major outcomes of the COST ENERGIC network is an edited book that is dedicated to the research on VGI, and we have decided that following the openness of the field, in which many researchers use open sources to analyse locations, places, and movement, we should have the publication as open access – free to download and reuse. To achieve that, we’ve approached Ubiquity Press, who specialise in open access academic publishing, and set a process of organising the writing of short and accessible chapters from across the spectrum of research interests and topics that are covered by members of the network. Dr Haosheng Huang (TU Wien) volunteered to assist with the editing and management of the process. The chapters then went through internal peer review, and another cycle of peer review following Ubiquity Press own process, so it is thoroughly checked!

The book includes 31 chapters with relevant information about application of VGI and citizen science, management of data, examples of projects, and high level concepts in this area.

The book is now available for download hereHere is the description of the book:

This book focuses on the study of the remarkable new source of geographic information that has become available in the form of user-generated content accessible over the Internet through mobile and Web applications. The exploitation, integration and application of these sources, termed volunteered geographic information (VGI) or crowdsourced geographic information (CGI), offer scientists an unprecedented opportunity to conduct research on a variety of topics at multiple scales and for diversified objectives.
The Handbook is organized in five parts, addressing the fundamental questions:

  • What motivates citizens to provide such information in the public domain, and what factors govern/predict its validity?
  • What methods might be used to validate such information?
  • Can VGI be framed within the larger domain of sensor networks, in which inert and static sensors are replaced or combined by intelligent and mobile humans equipped with sensing devices?
  • What limitations are imposed on VGI by differential access to broadband Internet, mobile phones, and other communication technologies, and by concerns over privacy?
  • How do VGI and crowdsourcing enable innovation applications to benefit human society?

Chapters examine how crowdsourcing techniques and methods, and the VGI phenomenon, have motivated a multidisciplinary research community to identify both fields of applications and quality criteria depending on the use of VGI. Besides harvesting tools and storage of these data, research has paid remarkable attention to these information resources, in an age when information and participation is one of the most important drivers of development.
The collection opens questions and points to new research directions in addition to the findings that each of the authors demonstrates. Despite rapid progress in VGI research, this Handbook also shows that there are technical, social, political and methodological challenges that require further studies and research

 

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.

Citizen Science and Policy – possible frameworks

Back in February, my report ‘Citizen Science & Policy: a European Perspective‘ was published by the Wilson Centre in the US. As I was trying to make sense of the relevance of citizen science to policy making, I used a framework that included the level of geography, area of policy making and the type of citizen science activity. This helped in noticing that citizen science is working well at the neighbourhood, city and national scales, while not so well at regional and international level. The reasons for it are mostly jurisdiction, funding and organisational structure and scale of operation.

Later on, at a workshop that was organised by Prof Aletta Bonn on Citizen Science and Policy impact, the idea of paying attention to the role of citizen science within the policy cycle was offered as another dimension of analysis.

Last week, at a workshop that was organised by the European Environment Agency (EEA) as part of their work on coordinating the European Protection Agencies (EPA) Network, I was asked to provide an introduction to these frameworks.

The presentation below is starting with noting that citizen science in an EPA is a specific case of using crowdsourced geographic information in government and some of the common issues that we have identified in the report on how governments use crowdsourced information are relevant to citizen science, too. Of particular interest are the information flows between the public and government, and the multiple flows of environmental information that the 3rd era of environmental information brought.

After noticing the individual, organisational, business and conceptual issues that influence use in general, I turn to the potential framing that are available – geography, stage in policy formation and mode of engagement, and after covering those I’m providing few examples of case to illustrate how specific cases fit into this analysis.

It was quite appropriate to present this framework in the EEA, considering that the image that was used to illustrate the page of the report on the Wilson Center site, is of the NoiseWatch app which was developed by the EEA…

Spatial Conversation – #VGIday #COSTEnergic

The COST Energic network (see VGIBox.eu ) is running a 2 day geolocated twitter chat, titled ‘Volunteered Geographic Information Day’ so the hashtag is #VGIDay. The conversation will take place on 14th and 15th May 2015, and we are universalists – join from anywhere in the world!
Joining is easy – and require 3 steps:

  1. Follow the @COST_Energic profile
  2. Enable your phone to disclose your position – this will allow to geocode your tweets.
  3. To participate to the discussion, use at least one of the dedicated hashtags in tweets: #COSTEnergic, #VGIday

What are we trying to do?

Discussions will be started by @COST_Energic. Through this twitter handle, we will share resources, results and ideas about the topic of VGI and geographic crowdsourcing. You can join the discussions, bring your ideas and links, and involve your contacts, and this will spread this event through the Twittersphere (and beyond?).
At the end of the experiment, we will produce a report of the generated discussion for our ENERGIC repository, and the dataset of tweets can be then used by researchers who want to visaulise, analyse and try to do things with it. It might end up as teaching material, or in IronSheep
