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?

Thanks for the ideas. I have to do it in C++ only - adding a database to this is not an option at this point. It probably would be easier if I had all the data in a DB, but right now I have a bunch of separate files and it's likely to stay that way in the foreseeable future.

Yes, I can do it in QGis, but I have to automate the process. It has to be done "in background".

Yes, I've gotten that far - I know how to get the required field values for a certain feature in a certain layer (there is actually just 1 layer in these files). But how do I know which feature I need to read?
