This has been the standard method of survey for sand cays and for small reefs with substantial dry-land areas (Kemp, 1937; Lofthouse, 1940a, 1940b; Stoddart, 1962). Horizontal angles are measured with a prismatic surveying compass, preferably about 10 cm in diameter and either tripod- mounted or hand-held; angles should be read without difficulty to half a degree.
