Abstract
This paper presents a test of a practical method for predicting the accu-
racy of a digital elevation model (DEM).
The test is based on profile sampling carried out photogrammetrically by
participants of the ISPRS, Commission III, W.G.3. Three different types
of landscapes are investigated.
Giving a fixed sample spacing and the precision of the DEM-data points,
the method yields an accuracy estimate for a DEM in the area considered.
