[gdal-dev] how to get gis layer information from GeoPDF (e.g. retrieve building polygon coordinates)

[Jared Rubin]

Even,
Would it be possible to do an ogr driver to get the vector features (I guess
similar to shape files? Or maybe update the pdf driver to dump  each
indivual vector feature into gdal metadata?
I'm not too familiar with GeoPDF, I just have seen how Adobe allows for
selection of specific vectors/objects/etc.

thanks
Jared
