Re: [gdal-dev] Zip-Compressed GeoJSON Files?

[Rahkonen Jukka via gdal-dev]

Hi,

I think this is documented in 
https://gdal.org/en/stable/user/virtual_file_systems.html#write-capabilities. 
At least after reading it I concluded that I must define both the zip file and 
the file to be inserted, and in that order.

ogr2ogr -f "geojson" /vsizip/output.zip/geojson test.shp

Test what I have
ogrinfo /vsizip/output.zip
INFO: Open of `/vsizip/output.zip'
  using driver `GeoJSON' successful.
1: test (3D Multi Polygon)

Same with 3.10.1.

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

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

This does not...

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

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.

Oops. So it is. Thanks, Jukka!
