Engr. Md. Shahidul Islam, +8801713062224, [email protected] , [email protected] , The original “datum” of the Indian subcontinent is commonly referred to as the Indian Datum of 1916 with origin at Kalianpur Hill where: Φo = 24° 07’ 11.26” N, Λo = 77° 39’ 17.57” East of Greenwich, and the ellipsoid of reference is the Everest 1830 where: a = 6,377,276.345 m, and 1/ f = 300.8017. The original topographic mapping of Bangladesh by the Survey of India was based on the Lambert Conical Orthomorphic projection, India Zone IIB where: the central meridian,λo = 90° E, the latitude of origin ϕo = 26° N, the scale factor at the latitude of origin mo = 0.998786408, and False Easting = 3,000,000 indian Yards, and the False Northing = 1,000,000 Indian Yards. (Note that 1 meter = 1.093619 Indian Yards.) 38. Gulshan Datum Survey of Bangladesh considers the national datum to be the Bangladesh Datum with its origin at Gulshan (in metropolitan Dhaka), where: Φo = 23° 47’ 49.48502” N, Λo = 90° 25’ 06.55270” East of Greenwich, the ellipsoid height, ho = +8.53 m, and the ellipsoid of reference remains the Everest 1830. The local Grid coordinates of Gulshan on India Zone IIB as published by the Survey of Bangladesh (SoB) are: Easting = X = 3,044,611.838 Indian Yards, Northing = Y = 733,492.5266 Indian Yards. Furthermore, the WGS84 coordinates of Gulshan are published by SoB as: ϕ = 23° 47’ 52.02714” N, λ = 90° 24’ 56.34024” E, and ellipsoid height = h = –45.4494 m.
