July 15th, 2009 · No Comments · FOSS4G, Geographic, OpenSource

Last week, I blogged about Open Street Map over on my company’s blog, The Viewshed about Open Street Map and touched briefly on the subject of data quality. I cited the study by Muki Haklay that compares (favorably) the quality of data found in OSM with Ordnance Survey data. More on the subject of OSM [...]
