<p>I have 2 rasters in GeoTiff format. One has all of the land
and water and the other is a mask file that shows either 0 for water or 1
for land. I basically want my output to just have the land values and
all the areas that were water in the first image to just be 0,0,0. Is
there a way to do this with any of the gdal command line tools?</p>
<p>Basically I want to do what gdal_rasterize does with a shp file mask but with a raster instead.</p>
