I'm trying to regenerate the index with GDAL 3.1.3 and PROJ 7.1.1 but it the script makes a lot of changes. The last commit was done with 3.1.4RC2?

@rouault I wonder whether the document with the "permission for use" from GSI should be attached.

I've just regenerate the index with GDAL master. The changes were due to change in forward slash escaping in GeoJSON

@kbevers Opinion ? We might possibly store it in the repo if it isn't too big (but make sure this is excluded from the tarball). Another option would be to send it to the OSGeo secretary so it is collected with other legal-like documents.

I would say that this is the right course of action.

FYI, I plan on releasing 7.2.0RC1 and PROJ-data 1.3RC1 on sunday or monday. It would be great if we could get this merge before that.

I've compiled GDAL's master but I get an undefined symbol error when trying to import the Python module. (demangled with c++filt it's OGRFlatGeobufLayer::OGRFlatGeobufLayer(char const*, char const*, OGRSpatialReference*, OGRwkbGeometryType, _IO_FILE*, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> >, bool))

@hernando Can you send the permission for use doc to secretary@osgeo.org (explaining a bit the context because Astrid won't be necessarily aware)

Make sure to 'make clean' before rebuilding. Anyway I'll merge this PR right away, and regenerate for you since I'm setup for this

Will do.
