Brigadier Martin Hotine CMG CBE (17 June 1898 – 12 November 1968)[3] was the head of the Trigonometrical and Levelling Division of the Ordnance Survey responsible for the 26-year-long retriangulation of Great Britain[4] (1936–1962) and was the first Director General of the Directorate of Overseas Surveys (1946–1955).

[5] He served on the North-West Frontier during the First World War and later in the Persian and Mesopotamian campaigns.

[4] Hotine was responsible for the design of the triangulation pillars constructed during the Geodetic resurvey of Britain.

[4] They provided a solid base for the theodolites used by the survey teams during the survey, thereby improving the accuracy of the readings obtained.

In the 1940s, Hotine developed a map projection for the Malay Peninsula and Borneo that is known as the Hotine oblique Mercator projection.
