General Description From 1905 to 1946, under the British rule, all the surveying works were undertaken by the Survey of India. At the end of World War II, the British government separated surveying works from Survey of India. On 1 st November 1946 Survey Department was established.
Old Triangulation Series Old Geodetic Datum: Indian Datum on Everest 1830 ellipsoid with Lambert conical orthomorphic projection. Topographic maps at scales of (1 inch =1 mile, 1 inch =2 miles, 1 inch = 4 miles) Maps were published in 1935-1944.
Lambert Projection One Inch Map (1 inch = 1 mile) Sample Map Sheet
Lambert Projection Half Inch Map (1 inch = 2 mile) Sample Map Sheet
Lambert Projection Quarter Inch Map (1 inch = 4 mile) Sample Map Sheet
Organization Survey Department is fully responsible for production of National Topographic Maps and Ground Control Points (GCP) establishment for the entire country. Main Objectives of Survey Department: - To produce National Topographic Maps - To demarcate the national boundary with neighboring countries

Establishment of Myanmar Datum 2000 The following factors are the main causes to reproduce the National Topographic maps with UTM (Universal Transverse Mercator) Projection 1) Most of the maps were produced last 70 years ago. 2) The old projection system of Myanmar, Lambert, was suitable only for the nations whose East-West extent is longer than North-South extent. 3) The units used in old map were in British System and not suitable for the modern mapping practice. 4) UTM Projection is widely accepted and used in the mapping world today. 10
Myanmar Datum 2000 Establishment of Transformation Parameters Identification and selection of (9) Primary Triangulation stations whose Indian coordinates are known and evenly distributed over the area of country to form a new primary horizontal network. They are:- 1) Myitkyina (Maru bum) 2) Kale (Hkwe-u taung) 3) Meikhtila (Taungpila) 4) Sittwe (U-Gin taung) 5) Kengtung (Loi Hsu Khan) 6) Yangon (Ngweya taung) 7) Kyaikkami 1 (Amherst Base Line, -near Htonman village) 8) Kyaikkami 2 (Kyaikkami) 9) Myeik ( Nattalin taung)
