The region of North-west Bohemia has been influenced by the open cast mining for more than the last hundred years. During this period has the coal mining activity become very intense leaving huge change on the landscape. We may require the original landscape for many purposes (historical, landscape renewal). One of the ways how to reconstruct the original shape of the landscape is the usage of historical maps and old aerial photographs made in the period before the dramatic georelief changes. As the data sources, we use the maps of the 3rd Military survey 1:25 000 after reambulation, aerial photographs taken in years 1938, 1952, 1995 and maps of stabile cadaster. The reambulated maps contain clearly readable elevation data (contour lines), which were used for reconstructing the original landscape. From processed aerial photographs we get the Digital Surface Model of the coal mines in different time periods.
