Is there a way to bring a GeoPDF into GRASS?
many thanks,

While I have no experience with that format, I see that GDAL
supports it:
http://www.gdal.org/frmt_pdf.html

So, r.in.gdal should do the job given a sufficiently new
GDAL installation on your computer.

Stephen, it would be nice if you could provide us some sample files to
test if the driver works well.
Thanks.

Unfortunately, at the moment the GDAL support for GeoPDF treats them entirely
as rasters --- the PDF data is converted to an image with the poppler library
and georeferenced using the data in the GeoPDF. GDAL 2.0.0 and later support
rendering only part of the image (vector, base imagery, text) rather than
all at once, but even so vector data in the GeoPDF is rendered into images.

It would be lovely if GeoPDF vector data could be extracted into Grass vectors,
but that's not possible through gdal yet, as far as I can tell.

I searched a bit but did not find any related email. So:
This would be a wish for OGR (hence, GDAL mailing list or tracker) since
GRASS relies on this library.
