A cave survey is a map of all or part of a cave system, which may be produced to meet differing standards of accuracy depending on the cave conditions and equipment available underground. Cave surveying and cartography, i.e. the creation of an accurate, detailed map, is one of the most common technical activities undertaken within a cave and is a fundamental part of speleology. 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 other areas of scientific study and assist visitors with route-finding.
Traditionally, cave surveys are produced in two-dimensional form due to the confines of print, but given the three-dimensional environment inside a cave, modern techniques using computer aided design are increasingly used to allow a more realistic representation of a cave system.
Famous quotes containing the words cave and/or survey:
“What difference is there, do you think, between those in Platos cave who can only marvel at the shadows and images of various objects, provided they are content and dont know what they miss, and the philosopher who has emerged from the cave and sees the real things?”
—Desiderius Erasmus (c. 14661536)
“When I survey the wondrous cross
On which the Prince of Glory died,
My richest gain I count but loss,
And pour contempt on all my pride.”
—Isaac Watts (16741748)
