r.patch

r.patch allows the user to assign known data values from other raster map layers to the "no data" areas (those assigned a category value of '0') in another raster map layer. This program is useful for making a composite raster map layer from two or more adjacent map layers, for filling in "holes" in a raster map layer's data (e.g., in digital elevation data), or for updating an older map layer with more recent data.
