line event per watercourse on a single map, up to two coloured lines are illustrated on each side of the watercourse. A 
priority setting ensures that, where watercourse illustrations overlap (e.g. in the vicinity of estuaries) the information 
about the most important of the two watercourses is shown. Point events are either illustrated on the watercourse axis 
itself or on the relevant side of the watercourse (e.g. at inlet points).

5 CONCLUSIONS 
This paper documents the efficient application of modern photogrammetric and GIS processes and methods in regional 
environmental planning. Thus in order to reduce time and costs, DSK-DG also implements laser scanning processes in 
addition to the traditional manual photogrammetric recording methods used for terrain modelling, which mainly provide 
ArcInfo enables the compilation of a homogenous and yet “dynamic” data basis for all parties involved in the creation 
of the general plan of projected mining for the first time, and thus consistent processing at different points. Dynamic 
Segmentation allows the simple addition of further thematic levels. This is certain to be of great significance for 
watercourse monitoring in future. The data created for the environmental assessment is stored in the central GIS data 
pool of DSK. It will therefore be available online to all interested parties via Intranet/Internet and is likely to provide the 
basis for studies which go beyond the creation of general plan of projected mining.
