Introducing theodolites for mapping in Norway
Christopher Hansteen, professor of applied mathematics at the University of Oslo, was appointed as a part-time director of geodesy at the Geographical Survey of Norway in 1817. He quickly realized that previous measurements of angles using geographical circles did not produce data of required quality for geodetic surveying. Using archival sources, the article describes how Hansteen acquired a theodolite from Germany and applied it to demonstrate …
