[OSM-talk-be] WMS (aerial) imagery covering Belgium, now conveniently packaged for adding it to JOSM

[Glenn Plas]

In my experience, the outlines and building shapes I've seen in GRB are
like 10 times better than all the work that exists using bing and other
sources.

A one on one copy would be silly, but if you bring it all together,
agiv/grb and osm data, it helps to make sense of what you are looking
at. Also it is conclusive usually when new buildings replace older.
It's the best source, I don't really care if the house isn't exactly as-is.

The housenumber inports will take years, but it's fine as it is as tons
of intelligent choices and conclusions, mistakes and other uglynes needs
to be fixed too. And it all helps, if you overlay them with some
transparacy adding GRB would be an awesome tool.

I've been doing housenumer entries for weeks now, grb layer would
defenitely be of good help.  But never a dumb copy.
