Cave cadastre

from Wikipedia, the free encyclopedia
Cadastral data in a cave plan

Cave registers in Germany and Austria collect structured information about caves . Comparable data collections are available in other countries.

Cave cadastre can be compared in many ways with the above-ground property cadastre : It describes the location, size, use by humans, animals and plants and the like.

Cadastral and history

In 1923 the National Federation of German speleologists at the instigation of Benno Wolf decided a central cavity cadastre establishing. In addition to Wolf, who himself traveled and documented numerous caves throughout Germany, the Harz cave researcher Friedrich Stolberg and Walter Freiherr von Czoernig from Austria were the driving forces behind the creation of the cadastre.

As part of the underground relocations in the last years of the Second World War, the cadastral data were brought under state control and used for armaments purposes.

Since the post-war period, the land registers in Germany and Austria have been managed decentrally, each by regional cave associations or individuals. The cadastral work is done on a voluntary basis - like caving in general .

In Germany, 7764 caves with a total length of 240 kilometers are recorded in the cadastre (status 2002).

Access to cadastral data

The data in the cave cadastre is based on often decades of laborious surveying and research work by cave associations and individuals. Therefore, data from the cadastre is often only passed on to a very limited extent. An example of the usual approach to data transfer:

“It goes without saying that the collected data cannot be freely available to everyone. The transfer of information requires a corresponding trusting cooperation from which all parties benefit. "( Michael Laumanns : Höhlenforschung in der Eifel, p. 23)

Significance and content of the cadastre

The cadastral data are not only important for further exploration of caves and direct cave protection , but also for nature and monument protection aspects, construction and water management and to a very significant extent also for fire brigades and cave rescue.

The cadastre contain clear identification of the caves, location, object description, photos, cave plan , information on geology , biology , etc.

Cadastral numbers

Similar to postcodes, the cadastral areas are broken down geographically. Cadastral numbers often consist of a 4-digit number that identifies the topographic sheet, followed by a consecutive cave number. Both numbers are separated from each other by a slash. In some cases, numbering is also carried out based on the landscape cadastre.

The Kluterthöhle has the cadastral number 4610/6 . This identifies the topographic map (4610 - Ennepetal ). The Klutert cave is identified by the number 6 as the sixth cave in the area that has been included in the cadastre.

Often the cadastral numbers are attached to a metal plaque on the cave.
