Mapserver sites with public map data in the US/Canada

[Jan Hartmann]

Folks,

For a German-Dutch funding proposal I am looking for Mapserver sites in 
the US and Canada that are based on maps which are not publicly 
available here in Europe, especially cadastral and large scale 
topographical maps. Preferebly these sites should be developed by small 
independent firms. A good example is Rich Greenwood's Teton County Map 
Server (http://www2.tetonwyo.org/mapserver/). I vaguely remember a 
housing server for New York, and a very large system for Portland City, 
but all pointers are welcome. We are trying to convince our local 
bigwigs that it can be profitable to make these data publicly available, 
both for government and for small to medium-sized firms. Those maps are 
completely monopolized by government and big business over here.

Please send me personally any pointers you can think of, and I'll 
summarize them for the list.

Thanks

Jan
