I have a lot of KML files set as lon-lat (geographic coordinates) and want to set them as UTM (E-N) and WGS84 with Python (using arcpy, ogr, or gdal)
Does anyone knows how to do this?
I think KML only uses Long-Lat coordinates (EPSG codes 3857 or 900913). You can try reprojecting to your local UTM projection and save them as another format (e.g. Shapefile, or GeoJSON or whatever).
where XXXXX is the EPSG code from your target projection (go here for clues as to what code to use)
