OSM Quality Assessment – S4 presentation

The following presentation is a summary of the OSM quality assessment paper that I’ve posted here in August. It was presented in the UCL Centre for Advanced Spatial Analysis (CASA) S4 event which was held on the 8th January 2009.

The presentation does not include additional analysis to what included in the paper, apart from a graph that analyses the bias of coverage in comparison to the Index of Multiple Deprivation (Slide 37) which shows the analysis for urban areas only. In the slide, only areas with size up to single standard deviation from the average are shown. By and large, this means that only urban areas are included.
