Hi all, I am trying to have gdal_contour operate on SRTM data from CGIAR (http://srtm.csi.cgiar.org/). The problem is that this dataset has oceans set to "nodata". This creates ugly artifacts along the shores (you can see an example here on the red lines: http://www.mguillaud.net/tmp/Screenshot.png - in contrast, the blue contour lines were generated by gdal_contour from another DEM file with sea-level at zero - however I can not use this second data source because it has other defects).
Now, I would like to either 1. set all "nodata" points to an arbitrary elevation (zero) directly in the GeoTIFF file, or 2. make gdal_contour assume that nodata means elevation zero. I would be grateful if anyone can point me to a way to do either of the above ! cheers, Maxime _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
