Central Geological Database – Caves Subsystem

The Central Geological Database Caves Subsystem (CBDG) contains standardized location, morphometric, bibliographic, nature data (geology, hydrology, biology, archeology, climatology and environmental protection), descriptive data (history of research, exploration and documentation) and graphic attachments (plans, sections and photos) according to the state of knowledge for the year, in which they were developed or updated. They are an excellent starting material for scientific specialized research. They reflect the authors' knowledge and maintain their style of description. This knowledge has been collected by the Polish Society of Friends of Earth Sciences ( PTPNoZ ) since the 1970s until today in the course of inventory work carried out by Polish speleologists. The aim of these activities is to obtain a complete set of documentation from all over Poland and to update them successively. The website is also a source of reference spatial data.
