Hi, I downloaded and installed today the TerraGo toolbar from http://www.terragotech.com/software/TerraGo_Toolbar.exe. I installed it on top of Adobe Reader XI v. 11.0.10.32. The TerraGo plugin does not seem to tell me anywhere what version it is. It seems that all the tools in the toolbar stay inactive when I open any geospatial PDF file which I had created with GDAL v. 2.0-dev. Only tool that worked for me was the GeoPDF File Properties tool which did find the georeferencing metadata from the ISO32000 version but not from the OGC_BP version. Anyway, the toolbar seems to be of no use for those who write geospatial PDF files with GDAL. I can also recommend to use the ISO 32000 encoding which makes the coordinates to appear in standard Adobe Reader. -Jukka Rahkonen- _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
