Speleology to cave science in the world. The growth of speleology is directly linked with that of the sport of caving, both because of the stimulation of public interest and awareness, and the fact that most speleological field-work has been conducted by sport cavers. The creation of an accurate, detailed map is one of the most common technical activities undertaken within a cave. Cave maps, called "surveys", can be used to compare caves to each other by length, depth and volume, may reveal clues on speleogenesis, provide a spatial reference for further scientific study, and assist visitors with route-finding. Caves provide
French Federation of Speleology of speleology within the (CNRS). On 28 May 1948, Jeannel met in Paris with the presidents of the clubs known to cavers as well as various eminent speleologists, under the auspices of the CNRS. This was the birth of the (CNS), whose headquarters was established at the Muséum national d'Histoire naturelle in Paris. The CNS consisted of the chairpersons of speleological organisations and some exceptional personalities who had "contributed in particular, for their work in the development of French caving". The inaugural committee comprised 21 organisation representatives or individuals, most of whom were scientists. Among the members was Robert de
