I am carrying out an exercise on digital mapping of soil properties. I have tried several high resolution DEMs like 90 m and 30 m but their resolution is not good enough. Kindly assist.

It depends on your area of interest. If you are just testing a method, one of the large coverage free DEMs with high resolution (2m) is ArcticDEM, but as its name say it covers the Arctic only (Alaska, Northern Canada, Northern Europe, Russia, etc.). You can check that one out (ArcticDEM)

This is the coverage of ArcticDEM enter image description here

  • $\begingroup$ Probably not much soil to analyze in that region. $\endgroup$

    $\begingroup$ I just added a coverage picture, as you can see there is PLENTY of soil in that region. $\endgroup$ Jan 11, 2018 at 17:47
