How can I get of the extent of all features within a GeoJSON FeatureCollection with Python 3? One extent for all features, not one per feature.

The Feature collection includes multiple points features and multiple LineStrings features.

If your FeatureCollection doesn't have a bbox member as described in RFC 7946, you will need to loop over all Features and update a global variable as you go.

The code found in this answer can serve as a starting point for your script.

  • Not sure about your location, but here it is getting late - maybe for you too... ;-) A point doesn't have an array of coordinates of course. :) For points it is simply: c1 = f["geometry"]["coordinates"][0] and c2 = f["geometry"]["coordinates"][1]. – Stefan Sep 8 '18 at 21:12
  • what about LineString. It's only 4:15pm here – Dean Sep 8 '18 at 21:15
  • See tools.ietf.org/html/rfc7946#appendix-A.2 You will have to find the outermost coordinates. I'm wondering if you aren't better off using node.js to compute bbox for your FeatureCollection: npmjs.com/package/@mapbox/geojson-extent – Stefan Sep 8 '18 at 21:26
