I have about 500 separate files containing GPS points in UTM coordinates from multiple zones.

I am looking for a simple and fast python or Php script that i can use to carry out a batch conversion for these files.

What file format do you have? – nagytech Aug 3 '12 at 3:59
The files are in Csv (spreadsheet) format – Shade Aug 3 '12 at 20:06
The procedure to identify the UTM zone is discussed at – whuber Aug 21 '12 at 16:47

proj.4 or GDAL/OGR might be useful. We can probably provide better answers if you tell us what file format you want to convert from, the UTM zone, and the target coordinate system.

The files are in csv format but the problem here is that the UTM zones are not usually specified by the field men, because their job is based on locations using the Canadian dominion land survey (DLS) system. I am thinking of the possibility of identifying the UTM zone using the range and meridian information that i have on the DLS names. Please I will appreciate contributions on this – Shade Aug 3 '12 at 17:18
What is the target coordinate system? – BradHards Aug 3 '12 at 22:23
The target coordinate system is NAD_1983_10TM – Shade Aug 7 '12 at 15:00

The easiest solution is to copy/paste your lat/long in UTM format to - you will get them instantly converted to any other popular coordinate format.

Petra, do you happen to know what datum hamstermap uses? Considering it says "Decimal degrees (Google Maps)", I'm assuming that it's WGS84, but I just wanted to make sure before I trust the output. Thanks. – Tom Dec 6 '13 at 20:02
