If I want to use a PCS to do distance calculations over a large area. For instance, lets say I want to calculate a 650km buffer around Pittsburgh, Pa. The buffer would go outside the state plane for Pittsburgh and outside the UTM zone. I decided to punt and just put everything in UTM Zone 17N and do the calculation that way, but I'm not sure if that is the correct thing to do.
http://jimkeener.com/posts/projections if anyone wants to see what I'm talking about or would be kind enough to give me feedback on the post (especially to point out if I'm wrong anywhere in it). In QGIS can't figure out how to create a buffer not in the native units of the projection the layer is part of. (i.e. a m-based buffer with GCS). Any help is appreciated. Jim
