[OSM-talk-be] Missing Slow Roads (was Re: IGN/NGI/NGI/NGI too now using OpenStreetMap)

[joost schouppe]

Marc,

The way to do this would be to overlay NGI data with our data. You could do
like frutellake did and check total length in squares of 1 km². Or you
could do it more properly using a data conflation tool. With something like
FME I would try to find a partner road for roads that exist in NGI. In case
there is no match, that would warrant closer inspection. When a road is of
a completely different type in NGI and our data, that would warrant a check
too.

I did this in a purely visual way with Wegenregister, which is mostly NGI
but only Flanders, and there were places where NGI was more complete - and
places where we are more complete.
