Bohrkarten

Bohrkarten, also known as drill maps or drilling maps, are specialized cartographic tools used primarily in the field of geology and mining. These maps are designed to provide detailed information about the subsurface of a particular area, typically for the purpose of locating and extracting valuable minerals or resources. Bohrkarten are created by compiling data from various drilling operations, which involve the insertion of boreholes into the earth's crust to collect samples and measure geological properties.

The construction of a Bohrkarte involves several steps. First, the location of each borehole is plotted on a base map, which can be a topographic map or a geological map. The depth and orientation of each borehole are then indicated on the map, often using symbols or color codes to represent different types of geological formations or mineral deposits. In some cases, the map may also include contour lines or cross-sections to provide a more three-dimensional representation of the subsurface.

Bohrkarten are essential tools for geologists and mining engineers as they help in understanding the geological structure of an area, identifying potential mineral deposits, and planning mining operations. They are also used in environmental studies, as they can provide valuable information about groundwater resources and soil contamination. The accuracy and detail of a Bohrkarte depend on the quality and quantity of the data collected from the boreholes, as well as the expertise of the cartographer in interpreting and presenting the information.
