Karen, For example this command on my computer
gdal_rasterize -burn 1 -l is50v_mannvirki_flakar_24122013 -of GTiff -ts 1000 1000 is50v_mannvirki_flakar_24122013.shp x.tiff
produces a 1000 x 1000 geotiff which is mostly zeros except ones where the polygons are.
Can you tell us what command did you use? Ari ps: the website was a bit difficult to use for non-icelanders. 13.12.2014, 06:18, Karen Pease kirjoitti:
Hi all, I'm running Fedora 21 with a fresh built gdal-1.9.2. Try as I might, I can't get gdal_rasterize to output anything other than purely transparent images, purely white images, or purely black images. I want to use it on this dataset - "Elevation data. GDB og SHP. ISN2004": http://atlas.lmi.is/LmiData/index.php?id=1079838344912 I've spent maybe 8 hours on this, including trying all sorts of different commandlines. After finding that I couldn't get that to work, I found some sample tutorials that includes a shp file and some command lines to use it with gdal_rasterize: http://disc.sci.gsfc.nasa.gov/dataholdings/?q=recipes/How-to-Obtain-a-Shapefile-based-Data-Subset-with-GrADS http://www.openforis.org/OFwiki/index.php/Special:WhatLinksHere/Example_data_set None of these work for me either (using it exactly as they say to), so I don't think it's my shp files that's the problem; I think it's gdal_rasterize or something it depends on. I know the problem isn't an image viewer problem either - I've tried multiple viewers, and I've tried saving the files to PNM to allow for manual inspection - they all contain only the same data value repeated over and over, no variation, just pure one color. What should I do? I really need to make a heightmap out of this landscape data for inclusion into a 3d model... - kv, Karen _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
