Yes, I want to be able to have the software convert automatically as needed. The area is in North Coastal BC. Its basically a modified projection that represents ground distances locally.

We have a local system that is based on UTM Zone 9. This local system is then scaled to ground coordinates, rotated, and shifted over. There is also an adjustment to the vertical but that can be ignored. This is a very large ongoing project. I am hopeful that Proj4 can handle scaling, rotation, and translation parameters. I want the option of using project coordinates or whatever else. I am primarily a Land Surveyor, so thats why some of this might sound weird to a strickly GIS person (which I just received training in).

Thanks for that link! That's a start anyhow! Any idea how I would fit those parameters above into the notation scheme? Is it possible? In GIS context, the vertical isn't as important as the horizontal.
