Brigadier Martin Hotine CMG CBE (17 June 1898 – 12 November 1968) was the head of the Trigonometrical and Levelling Division of the Ordnance Survey responsible for the 26-year-long retriangulation of Great Britain (1936–1962) and was the first Director General of the Directorate of Overseas Surveys (1946–1955).
He served on the North-West Frontier during the First World War and later in the Persian and Mesopotamian campaigns. He has been described as "decisive, ingenious and tough".
Cartography
Hotine was responsible for the design of the triangulation pillars constructed during the Geodetic resurvey of Britain. 6,173 of these were built. They provided a solid base for the theodolites used by the survey teams during the survey, thereby improving the accuracy of the readings obtained. They are sometimes referred to as "Hotine Pillars".
In the 1940s, Hotine developed a map projection for the Malay Peninsula and Borneo that is known as the Hotine oblique Mercator projection.
Personal life
Hotine was married to Kate Amelia Hotine (née Pearson)(1895–1987) whose nickname to family and friends was 'Ajax'.
