[gdal-dev] Zip-Compressed GeoJSON Files?

[Simon Eves]

Revisiting our geo export options after several years and hit something
weird.

Testing with the command-line tools, this works...

ogr2ogr -f "geojson" /vsigzip//path/to/output.geojson.gz <input>

This does not...

ogr2ogr -f "geojson" /vsizip//path/to/output.geojson.zip <input>

It spits a ton of errors (attached) and while the zip file is created, it
has no files in it.

Am I doing something silly, or is this a bug?

Does anyone really use or expect individually-zipped GeoJSON files anyway?

This is with GDAL 3.7.3. We are updating to 3.11 so I'll try that too.
