Using Open Street Maps and Kalman Filters to Clean Up GPS Data

Slightly related: I'm driving through West Africa now, and I loaded OSM onto my cheap-o used Garmin. [1]

I have been absolutely shocked and blown away by the accuracy and detail of the maps. In the tiniest dirt street village, with less than 100 people, it correctly maps all the roads and even all the walking trails.

Of course, in the big cities too.

I'm staggered they have this level of detail.

Totally. Have you seen OSM Analytics - it has some really visualizations on how the data of geographies has evolved over time - in terms of roads, buildings etc. This link[1] shows Tanzania, for example.

The mapping in west africa could be from the Humanitarian OpenStreetMap Team
