Re: [gdal-dev] ogr2ogr: Unable to open datasource [SVG, PDF] with the following drivers
Klo, it turned out afterall that DXF is not such a great choice in my case. `pstoedit` is best tool for rapid conversion, but it does not respect polygons present in initial PDF files, but it just samples polygons to very small lines which is such bad outcome. Evan, or anybody else, can you please link me to SVG DTD that ogr2ogr would understand? The link provided here: http://www.gdal.org/drv_svg.html is dead, and on their (cloudmade) web portal I can find any information about their custom SVG format. No formal DTD, but here's a sample file : http://svn.osgeo.org/gdal/trunk/autotest/ogr/data/test.svg I also assume there is no tool that can make initial PDF valid for ogr2ogr. No, it just needs a bit of extra coding in the PDF driver.

Le mercredi 28 mai 2014 22:10:51, klo uo a écrit : Hi, I have vector data in PDF format, which I tried to georeference with org2ogr -gcp feature and output basic Shapefile, but program complains that it's unable to read the PDF file, which I confirm as valid by processing it with ghostscript. I then converted PDF to SVG and confirmed that SVG is well-formed and valid XML, but again ogr2ogr complains about it. Finally by converting initial PDF to DXF, ogr2ogr was able to complete the task. I want to avoid converting PDF to other format and especially to DXF which makes the process slow, so I'm hoping for advice. I can provide the test files if necessary. Thanks. Could you provide the test file ? The PDF vector reader has some limitations, and works best with structured PDF. As far as SVG is concerned, the SVG reader is also currently limited to a particular formation of SVG : http://gdal.org/drv_svg.html Even -- Geospatial professional services http://even.rouault.free.fr/services.html ___ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
