Finally, after 2 years in the making, Interacting with Geospatial Technologies is out. It is the first textbook dedicated to usability and Human-Computer Interaction (HCI) aspects of geographical information technologies. It covers desktop, Web and mobile applications and how they can be designed so they are more effective, efficient, error-free, easy to learn and enjoyable, which is one version of the 5 E’s of usability.
I started thinking about the book in 2004, when I realised that the most recent academic books dedicated to HCI and GIS were published in 1993 and 1995. These are respectively David Medyckyj-Scott and Hilary Hearnshaw’s Human Factors in Geographic Information Systems and the collection of papers from the NATO workshop Cognitive Aspects of Human-Computer Interaction for Geographic Information Systems, edited by Tim Nyerges, David Mark, Robert Laurini, and Max Egenhofer. While these books and the collections of papers in them are still valuable, it must be noted that in the early 1990s, Web-based GIS was just starting to appear, desktop GIS was fairly basic, mobile GIS was not even experimental and GIS trade journals argued about which UNIX workstation is the best for GIS.
Apart from these books, the proceedings of COSIT (Conference of Spatial Information Theory) are also valuable sources of academic research on spatial cognition and other principles of geographical and spatial information, and there are also many papers in academic journals about GIS.
However, not much attention was paid to everyday use of geographical information technologies, and no textbook included an introduction in a form accessible to postgraduate students and software developers. So, after complaining in various conferences that there is a clear need for such a book, I started working on it. It was an interesting process to identify suitable authors and encourage them to contribute to the book.
While offering the breadth of several authors who specialise in different aspects of the field, I think the textbook is coherent and consistent, and its style both accessible and readable. The editing process was more active and time-sensitive than is often the case in academic books, to ensure that the textbook is usefully up-to-date. On UCL’s MSc in GIS, a recent course based on the textbook was well received by students.
The book covers the principles and the practical aspects of interaction with geospatial technologies. There are sections about spatial cognition, cartography, user-centred design and usability engineering – here is the table of contents.
So, now you can get your own copy – and any feedback is welcomed.
Usability of VGI in Haiti earthquake response and the 2nd workshop on usability of geographic information
27 March, 2010
On the 23rd March 2010, UCL hosted the second workshop on usability of geographic information, organised by Jenny Harding (Ordnance Survey Research), Sarah Sharples (Nottingham), and myself. This workshop was extending the range of topics that we have covered in the first one, on which we have reported during the AGI conference last year. This time, we had about 20 participants and it was an excellent day, covering a wide range of topics – from a presentation by Martin Maguire (Loughborough) on the visualisation and communication of Climate Change data, to Johannes Schlüter (Münster) discussion on the use of XO computers with schoolchildren, to a talk by Richard Treves (Southampton) on the impact of Google Earth tours on learning. Especially interesting are the combination of sound and other senses in the work on Nick Bearman (UEA) and Paul Kelly (Queens University, Belfast).
Jenny’s introduction highlighted the different aspects of GI usability, from those that are specific to data to issues with application interfaces. The integration of data with software that creates the user experience in GIS was discussed throughout the day, and it is one of the reasons that the issue of the usability of the information itself is important in this field. The Ordnance Survey is currently running a project to explore how they can integrate usability into the design of their products – Michael Brown’s presentation discusses the development of a survey as part of this project. The integration of data and application was also central to Philip Robinson (GE Energy) presentation on the use of GI by utility field workers.
My presentation focused on some preliminary thoughts that are based on the analysis of OpenStreetMap and Google Map communities response to the earthquake in Haiti at the beginning of 2010. The presentation discussed a set of issues that, if explored, will provide insights that are relevant beyond the specific case and that can illuminate issues that are relevant to daily production and use of geographic information. For example, the very basic metadata that was provided on portals such as GeoCommons and what users can do to evaluate fitness for use of a specific data set (See also Barbara Poore’s (USGS) discussion on the metadata crisis).
Interestingly, the day after giving this presentation I had a chance to discuss GI usability with Map Action volunteers who gave a presentation in GEO-10 . Their presentation filled in some gaps, but also reinforced the value of researching GI usability for emergency situations.

The Digital Economy is a research programme of Research Council UK, and as part of it the University of Nottingham is running the Horizon Digital Economy research centre. The institute organised a set of theme days, and the latest one focused on ‘supporting the contextual footprint – infrastructure challenges‘. The day was excellent, covering issues such as background on location issues with a review of location technology and a demonstration of car pooling application, data ownership, privacy and control over your information and finally crowdsourcing. I was asked to give a presentation with a bit of background on OpenStreetMap, discuss the motivation of contributors and mention the business models that are based on open geographical information.
For the purpose of this demonstration, I teamed with Nama Raj Budhathoki who is completing his PhD research at the University of Illinois, Urbana-Champaign under the supervision of Zorica Nedović-Budić (now at University College Dublin). His research focuses on user-generated geographical information, and just before Christmas he run a survey of OpenStreetMap contributors, and I was involved in the design of the questionnaire (as well as being lucky enough to be on Nama’s advisory committee).
So here is the presentation and we plan to give more comprehensive feedback on the survey during State of the Map 2010.

The Commission on Use and User Issues of the International Cartographic Association (ICA) is currently working on a new handbook specifically addressing the application of user research methods and techniques in the area of geographical information and its applications.
In order to share experiences and interesting case studies a workshop is organized by the Commission, in collaboration with UCL, on the day preceding GISRUK 2010, Tuesday, 13th April 2010.
The programme for the workshop is now completed and the programme and abstracts for the papers that will be discussed during the meeting are available here.
For information on the commission, visit the website of the ICA Commission on Use and User Issues and to register to the workshop follow the instructions on the GISRUK2010 website.
