Rock drawing (cartography)
As Petroglyph or rock signature in is mapping the type of relief representation refers to the on großmaßstäbigen maps the structure of the rocks is presented.
Often in the mountains, due to the rugged, steeply sloping, sometimes vertical rock formations, the terrain can no longer be represented only with isolines , as these would be too close to one another. In such cases, the cartographers draw a rock drawing made of lines, points and hillshades in order to be able to reproduce such terrain structures well. If possible, the isolines are drawn in so that the slope of the terrain can be derived from them.
Other mountain formations such as gutters , rubble heaps , lava outflows , sinkholes , karst quarries, etc. are supplemented by various other map symbols.
The map of the Berchtesgaden Alps, published in copperplate in 1826, already contained a schematic rock drawing. Today, the 1: 25,000 and 1: 50,000 maps of the Alpine clubs in Germany and Austria and the Swiss Federal Office of Topography are particularly well known for their high quality rock drawings and are also well suited for alpinists .
