I'm adding two rasters that have different extent. The result is a raster with the extent of the smaller one, which is not what I want. What do I need to do to have the output raster as big as the biggest of the input rasters? I have tried to increase the extent of the smaller one with "Copy Raster" and in 'Environments' I have selected the biggest raster as 'Extent' and 'Snap Raster'. This has not worked unfortunately.
Am I doing anything wrong? Is there any other way to do what I'm trying to do?
NOTE: I need to extend the smaller raster and set all those new cells to 0.
