I have some georeferenced pdf's that I would like to open in QGIS. I have read that GDAL version 1.8 and higher will support pdf, and I have GDAL 1.10 installed with QGIS 2.0 on Windows 7, but when I add raster layer then choose my pdf file, I get an error that my file is not a supported source.
I downloaded probably the same pdf from http://pub.data.gov.bc.ca/datasets/177864/pdf/092f/092F088.pdf Then I run gdalinfo with GDAL 1.10 on Windows 7 64-bit. GDAL was installed from gisinternals.com. Gdalinfo finds georeferencing
Then I tried to open the pdf with QGIS 2.0.1 and it fails. Conclusion: We both have a QGIS version that does not support pdf. While awaiting such a build that has the support you can convert geospatial pdf files into GeoTIFFs with gdal_translate by using the binaries from gisinternals. The pdf driver in GDAL is exceptional because write support is compiled by default but for read support GDAL must be especially compiled with libpoppler or libpodofo.
The issue should have been fixed for Windows builds with this ticket: http://trac.osgeo.org/osgeo4w/ticket/408 for OSGEO4W GDAL and the QGIS 2.4.0 and dev versions from the setup installer.
gdal_translate works now (it takes some time), even inside QGIS with
Maybe the data is too big for QGIS memory.
