OGR2OGR Esri JSON to GeoJSON - Rings returning as null in geometry?

Question

I'm trying to convert an Esri JSON file to a GeoJSON format using ogr2ogr. For some reason, in the objects returned, the geometry field is constantly null.

Here's the script I'm running:

ogr2ogr -f GeoJSON output.geojson input.json

Here's the input file: https://pastebin.com/RSx4L1vT

Here's the output file: https://pastebin.com/9tHnm2ZH

Here's the original source of the data which I have cleaned up: https://bexleycouncil.maps.arcgis.com/sharing/rest/content/items/95a6e51df1734a859a502109a188790a/data?f=json

I'm fairly new to OGR/GDAL, and know it's something to do with the rings format, but I can't figure it out.

Answer 1

Assuming you can use Python 3, there are 2 ways to approach this issue:

1. Write a Python code (the longer way but you have better control to use precision, geometry type, and compliance checker using geojson_rewind.

2. Use the available python library: arcgis2geojson from here

Output: Here is a sample output using the second approach:

Additional comments:

• I did not change your original SRS to latitude-longitude etc.for quick visualization.
• I am unsure if OGR has ESRIJSON driver to deal with your input data and it was easier to use the Python library.
