[gdal-dev] Reading shapefile from ZIP archive (c++)

[Daniel Evans]

Hi Sharon,

I think all you need to do is define the path to open as:

'/vsizip//parks-and-recreation-feature-map-d.zip/parks-and-recreation-feature-map/parks-and-recreation-feature-map.shp'

i.e. defining the filepath as:

/vsizip/<path to the zip>/<path inside the zip>

When the zip contains only a single (shape)file at the top level - the
case where you've got it working - GDAL automatically determines the
file to open.

Docs at: https://gdal.org/user/virtual_file_systems.html#vsizip-zip-archives

Cheers,

Daniel
