Yes, you should always ask such an entity. Chances are pretty good that they already have aerial imagery and geodata. Different government entities have different policies. The US Government has the principle that it cannot claim copyright on data produced at taxpayer expense, so everything it does is public domain. Some state governments feel the same way. Others are wiling to share, but only within a closed group (like the New York State GIS Consortium -- which I liken to the Roach Motel of geodata: data checks in, but it never checks out). The only way to find out is to ask. And if they try to claim copyright, you could point out that the US Government provides all its information freely. Whether they like the USG or not, that's a reason to do better than them (us). -- Russ Nelson - http://community.cloudmade.com/blog - http://wiki.openstreetmap.org/wiki/User:RussNelson [email protected] - Twitter: Russ_OSM - http://openstreetmap.org/user/RussNelson _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
