@BradHards, Yes, you're right. I wasn't sure which one I'd use at first.

@BradHards Maybe I can. A Proj.4 way seems more lightweight for this task. GDAL is a much bigger library.

comment Negative UTM easting
If I have negative eastings, can I use the same formulas (e.g. whatever wikipedia has) for lat,lon conversions though?

comment Negative UTM easting
My domain is over a part of North America. The outlying points are just slightly outside the UTM zone and the entire domain is about 1500 by 1500 km. I'll probably stick with pyproj for now. Although, it seems like an overkill for what I need to do.

comment Negative UTM easting
My outlying point is just slightly (about 100km) outside the UTM zone. I can certainly do the conversion using gdal or proj.4 Python bindings, but that adds a lot of dependencies to my project... I was very happy with this little Python library until I hit this wall :)

Yes, I think it sounds like what I need to do. I'll give it a try and see where it leads me. Do you happen to have any code examples for spatial queries?
