<br><br></blockquote><div>Is there a GRASS function in QGIS for r.patch? It uses both datasets, and uses one to fill the NULL values of another. Would probably have to make sure the computational region is set to accommodate the extent of merging both DEMs (maybe not necessary if r.patch doesnt regard region settings).</div>
