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
International Union of Speleology International Union of Speleology International Union of Speleology (, UIS) is a non-profit, non-governmental organization to promote interaction between academic and technical speleologists from a wide range of nationalities for the purpose of developing and coordinating international speleology in all of its scientific, technical, cultural and economic aspects. It formed in 1965 upon the initiative of the International Speleological Congress (held every four years since 1949) Its voting members consist of a delegate from each member country representing the cavers and speleologists of that country, rather than any of the official national bodies. Its activities take place in a number
