All the talk lately about offline maps prompted me to try converting the latest USGS Topo maps from geoPDF format to geoTiff using the geopdf2gtiff.pl script. I did this back in 2011 or 2012 after Tom KM5VY created the script. At that time it was a requirement (at least in the Ubuntu/Debian world) to install gdal from source because the version in the repository was too old.
The binary version of gdal in today's Ubuntu repo's is newer than the one I had to compile 3-4 years ago, so I thought I would give it a go using that. I downloaded a geoPDF map for my area, and ran the script. $ ./geopdf2gtiff.pl -f VA_Leesburg_20130613_TM_geo.pdf User asked us to fudge the neatline, finding nearest 7.5 minute quad boundaries Warning 1: libXML: 0: Element 'GeometryField': Character content other than whitespace is not allowed because the content type is 'element-only'. Creating output file that is 12245P x 12245L. Processing input file VA_Leesburg_20130613_TM_geo.pdf. Using band 4 of source image as alpha. Using band 4 of destination image as alpha. ERROR 1: Bad color space dict' ERROR 1: Pos = 9046254, Bad image parameters ERROR 1: Bad color space dict' ERROR 1: Pos = 9046254, Bad image parameters ERROR 1: Bad color space dict' ERROR 1: Pos = 9046254, Bad image parameters ERROR 1: Bad color space dict' ERROR 1: Pos = 9046254, Bad image parameters ERROR 1: Bad color space dict' ERROR 1: Pos = 9046254, Bad image parameters ERROR 1: Bad color space dict' I aborted the script at this point. Oh well, it appears the latest geoPDF's have issues. I could try building gdal from source including compiling in the required poppler support, but if the issue was gdal or poppler related I think the errors would be different. Also I was trying to find an offline map solution that did not require building a package like gdal from source.
