You have a DEM of unknown source, but theoretically with better precision, and a DEM from SRTM. You want know how close the elevation values differences between the two DEMs are, in order to send people to the field to do some surveying.
I made this reference:

Project: 02:14
Create Random Points 05:00
Extract Multi Value to Points 06:20
