Elevation models (DSM and DTM) of
closed open pit mines serve as high resolution basic data set for:
-
change monitoring of the
landscape (DSM)
-
detection of break lines and
processes of subsidence (DTM)
-
designation of zones threatened to
collapse
-
planning of re-cultivation measures
-
environmental compatibility studies

Extraction
of contour lines out of the elevation models for:
-
monitoring of degradation and
refilling
-
detection of subsidence caused by
mining
-
overlay with additional information in a GIS

Elevation data of active open
pit mines and re-cultivation areas a basis for:
-
official approval procedures
-
efficiency and security controls computation of volumes
-
simulations of arising ground water
