I am using ArcGIS Desktop.
I have two DEMs in .tif format and I am looking to merge the two. The main problem with merging these are that they are different resolutions (one is 10m and one is ~20m). Also, another problem with merging the two is that they overlap and I am not sure of the most effective way of dealing with that overlap. Obviously I want to keep the values of the better resolution.
So what are the best methods here?
- Is there a python script available that works best with merging rasters? I would like to automate this with a script if possible.
- Which process of resampling is best for DEM data? Bipolar, Cubic... ?
- What is the best way to merge overlapping DEMs?
