The theory of EDM-height traversing is summarized and the necessary formulae are given. A practical test executed in Australia is discussed in detail, and the results of investigations in other countries are reviewed. In the Australian Test; a standard deviation for 1 km of reciprocal EDM-height traversing of ±4.3 mm was achieved. It is found that EDM-height traversing fulfils easily the specifications for third-order levelling and that it should replace geodetic levelling in many cases on economical grounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
