I have two DEMs (geotif), one is of a larger area and the other of a smaller area located in the middle of the first DEM. The smaller area has some changes in elevation, next to the river banks there are newly formed landfills. I need them combined, so I have one DEM that embodies greater area with newly formed landfills.
I am using ArcGIS 10.4, DEMs are 32 Bit floating point, geo-referenced. I could not attach them because of their size.
Could someone guide me through the process, please?
