Calculate Elevation/Slope Stats
Elke
Global Mapper User
Hello!
I created a grid file displaying an isopach map of andosol thickness on which I imported surface features (drainage areas). I want to use the calculate elevation/slope stats to obtain the average andosol thickness in a specific drainage surface. I used 0.1m as a minimum elevation value for the isopach map and I replaced Invalid with 0m, but still if the drainage area is covered by a large part below 0.1m, it considers it as 0.1m and not 0m. Therefore, my averages thicknesses are overestimated. How can I solve this?
Thanks.
