How I can to draw using GDAL in python or c a polygon shapefile shape.shp with a GeoTIFF as background background.tiff file?

Both files are in the same projection.

The result could be a PNG, JPEG or whatever. To clarify I'm going to put screen shoots of the done with QGIS. First one is the shapefile, second the GeoTIFF, and finally the union.

  • Are you wanting this to be scripted, or a one time thing?

    Add alpha to the gdal_rasterize command as in here gis.stackexchange.com/questions/176471/…. There are other usable answers as well, search with "gdal_rasterize".

One method would be to rasterize the shapefile using gdal_rasterize, and then overlay it onto the other raster file.

A similar question exists and is available here: how to overlay shapefile and raster?
