Hello all I work at a BC Ski-hill... what I need is a method to quickly but accurately measure the depth of dense snow (man-made snow, some might call it ice). Traditional method of mechainically boring through to ground is slow, inaccurate & messy. New GPS based methods require detailed gps mapping & a benchmarked local gps transmit station ($$$). The goal is to be able to quickly & accurately survey the snowdepth of a wide area. Sonic is no good, since density of the snowpack may vary widely, with interspersed ice layers. Q1: Can a radar or other RF reflective measure quickly & accurately measure the depth of dense snowpack? Typical range 30 - 200 cm. Q2: Any existing product relevant information would be appreciated.
