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.
