GDAL Integration

[ibgreen]

deck.gl-native could leverage the extensive data format support in GDAL

see e.g https://gdal.org/doxygen/classOGRLayer.html

[ibgreen]

Pushed branch ib/gdal that installs gdal via vcpkg.

Issues:

• On MacOS it takes half an hour to build all dependencies (a very long list of compression library dependencies that we likely don't need).
• This install could be almost OK if only done once per developer, but would kill CI if also happens on linux.
• We either need to find a version of GDAL that doesn't include all those dependencies.
• Or make the compilation of GDAL dependent loaders optional and disabled in CI.
• Or create a second build target for those libraries,
• etc.
• Once integrated, we should be able to make a converter from GDAL feature collections to Arrow tables (similar to @loaders.gl/gis module)

On Ubuntu Linux, can we just install libgdal-dev libgdal20? Ubuntu Bionic has version 2.2.3+dfsg-2

[ibgreen]

Yes... Does that come with headers etc? Or is that just the link library?

[isaacbrodsky]

-dev suffix is the package with headers, non-suffixed is the shared object.

$ dpkg-query -L libgdal-dev libgdal20

Nice. Looks like it is available on homebrew too: https://formulae.brew.sh/formula/gdal
