GeoJSON to bounding box utility
This utility will find the minimum and maximum coordinates in a given GeoJSON file and format them as a GeoJSON bounding box.
It is more of a proof-of-concept and it will sometimes fail. Please contact the author with feedback.
Usage
python -m geojsonboundingbox "/path/to/myfile.geojson"
For anything more advanced, please look into the shapely
Python library.
