[gdal-dev] Use gdal_rasterize for two different layers with two different channels

[Oliver Rausch]

Hi all,
I have two tables of geometries that I'd like to rasterize onto one
output. I can rasterize the tables individually using

gdal_rasterize -burn 255 -sql "SELECT way FROM lines" PG:'...' -te ...
-ts ... out.tif

Is there a way to get a raster where, for instance all the lines from
one table are on the red channel, and all the lines from the second
table are on the blue channel?

Thanks,
Oliver .
