Brigadier Martin Hotine CMG CBE (17 June 1898 – 12 November 1968)[1] was the head of the Trigonometrical and Levelling Division of the Ordnance Survey responsible for the 26-year-long retriangulation of Great Britain[2] (1936–1962) and was the first Director General of the Directorate of Overseas Surveys (1946–1955).[3]

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".[2]

Cartography

Hotine was responsible for the design of the triangulation pillars constructed during the Geodetic resurvey of Britain.[2] 6,173 of these were built.[2] They provided a solid base for the theodolites used by the survey teams during the survey, thereby improving the accuracy of the readings obtained.[2] 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.[4]

Personal life

Hotine was married to Kate Amelia Hotine (née Pearson)(1895–1987) whose nickname to family and friends was 'Ajax'.[1]
