[Qgis-user] UNION OF FILE VECTORS (different geometry) and rasterize

[Sebastian Gutwein]

I often use the saga patching tool to overlay rasters.
http://www.saga-gis.org/saga_tool_doc/2.2.6/grid_tools_5.html
First you would need to rasterize each of your shape files and then use the
patching tool with whatever raster you want to end up on top as the patch
grid.
