My guess - London.  I'll take a look.  I've been making these maps in
ArcGIS, but I'd like to start using GRASS a lot more.  Has anyone imported
the OSM XML into GRASS?

What would also be interesting would be to interpolate the points, set a
threshold, and see how the thresholded surface compares to the lines formed
by segments and ways.  Before I start doing this has anyone tried it before?
