[gdal-dev] Trouble with georeferenced PDF

Thu Mar 1 04:34:32 EST 2012

Hi,

I had a quick test by converting one GeoTIFF into georeferenced PDF files with different parameters and opening results with Acrobat Reader and TerraGo toolbar.

For TerraGo the metadata must be in OGC_BP style and ISO style metadata must not exist (option BOTH does not work). What is odd is that TerraGo toolbar finds coordinates if I run gdal_translate with -a_srs
epsg:3067 but not if I run it with -a_srs epsg:32635.
There seems to something different in the PDF headers, here are short captures
from the beginnings of the files

EPSG:32635 which is not understood by TerraGo toolbar

EPSG:3067 which is OK for TerraGo
