The convert.py script reads lines with coordinates (and additional text field) from a file, and converts the coordinates into WGS84, if specified in UTM format.
./convert.py -v -c config.yaml -d input.csv
The configuration is specified in config.yaml, and requires a "center coordinate" plus a maximum distance (in meters). Every input coordinate is verified against this coordinate, and if it exceeds the maximum distance, an error is raised. If you do not want any error checking, just raise the maximum distance to a very high value.
