GISRUK 2013


On the 3rd to the  5th of April I attended GISRUK (Geospatial Information Research in the United Kingdom) to give a paper on Community Mapping as a Socio-Technical Work Domain. In keeping with Christoph Kinkeldey‘s love of 1990s pop stars Vanilla Ice made a second slide appearance, leveraging the fact it’s a very technical academic title. In short I’m using Cognitive Work Analysis (CWA) to create a structural framework to assess the quality (currently defined by ISO 19113:Geographic Quality Principles – well worth a read…) where there is no comparative dataset.

CWA is used to assess the design space in which a system exists, not the system itself. In taking a holistic view and not enforcing constraints on the system you can understand what components and physical objects you would need to achieve the values of the system and vice-versa. In future iterations I’m going to get past first base and look at decision trees and strategic trees to work out how to establish the quality of volunteered geographic data without a comparative dataset. Building quality analysis into day one, as opposed to being an after thought.
