I am using
gdal_rasterize to create a raster of a huge file containing polygons. I managed to generate the raster file with the right color and with the minimum size to tile it after with the
gdal_rasterize -of GTiff -co COMPRESS=DEFLATE -b 1 -b 2 -b 3 -burn 136-burn 46 -burn 17 -co PREDICTOR=2 -co ZLEVEL=9 -ot Byte -a_nodata 255 -a Niveau -ts 500000 500000 -l layer W:/layer.shp W:/layer.tif
Tile will be used to overlay Google Maps so the polygon must be transparent.
Has anybody experimented with this usage of
gdal_rasterize and succeeded in setting the opacity of the output raster?
