I am trying to merge two height maps in QGIS.
I have DEMs of the lake of constance in germany. It is a result of a goverment project and the data is available in a asc format. I want to 3dprint a landscape relief model. Also i need to split that model into pieces (200x200mm) to print it in blocks for a total length of 1000cm.
There is no problem to import the data in Qgis, also it is no problem to split the height maps into pieces for 3d printing. The fun begins when i try to merge the two DEMs into one. The DEM of the surrounding area ends where the lake begins.
Is it possible to "insert" the lake into the image of the surrounding area and recolor it?
The deepest point in the new DEM should be the darkest in the whole new DEM. At the end i need a single height map. --> Target: DEM of the whole area wir a dried of lake.
Shows only the surounding area
