如何将这些GPS坐标转换为有效的Google Maps坐标？

Question

I am getting GPS values from my GPS logger like this:

3250193.00 E
1115573.00 N

What type of GPS co-ordinates are these? They look like UTM co-ordinates. How to decode them to proper Google Maps co-ordinates?

Answer 1

Coordinate conversion isn't a trivial thing - you need to know what format your data is in before you start, and then use the appropriate geographic transformation.

Once you establish what data you're starting with you can use a library like GDAL to do the transformations:
