  1. Areal rainfall estimation from ground sensors


  2. Checking the results of a geophysical or other remote sensing technique by walking over the area and examining geological features.

    For example, the survey might find a proposed geological contact or major structure at surface. These should be able to be examined on the ground. If they are not there, it casts doubt on the results of the survey.
