Brent,
I was also digging a bit on this matter. It's true that the blogger only opens
our appetite as there is no more details on how to do it generally. I mean, for
UTM maps it has become fairly obvious how one can do it. The relevant part in
the

Joaquim,
Doing the format conversion from .ps to pdf is one thing (and there are
several ways to do it), but embedding the georeferencing in the PDF to make it a
GeoPDF is the interesting bit. I haven't found any open source project capable
of do that. Or even capable of writing the PDF el

Unfortunately all PDF parsing libraries I know are GPL, and that means
we can't use them for the gdal driver - because of the license issues.
But to create a GPL utility for converting GeoPDF to anything what

Hi,
There is a great blog post (and the linked "worked example" post with details):
http://geopdf.blogspot.com/2009/02/geopdf-map-for-worked-example.html
It shows you how to create geopdf via GhostScript - so there is
already a practical open-source example how to encode the georeference

Keith,
No talk that I'm aware of. There was a little chatter on the Geowanking list:

And occasionally some interest about producing PDF from Mapserver (e.g.

Hello people,
Is there any talk about developing tools in GDAL/OGR to extract raster or
vector data from a GeoPDF now the 2.2 version was submitted to the OGC?? The
submitted specs are for the georeferencing aspect only. ArcGIS and TerraGo
tools can create a GeoPDF. The USGS offers free Geopdf tha
