Bangladesh Transverse Mercator (BTM) A projected coordinate system has a flat, 2D surface with constant lengths, angles, and areas across the two dimensions. Which makes it easier to calculate properties  like area, distance of a object in map. UTM (Universal Transverse Mercator) is a widely used projected coordinate system which divides the Earth into sixty zones, each in six-degree interval. As Bangladesh lies between UTM Zone 45N and 46N, FAP19 has adopted a Transverse Mercator projection for Bangladesh. Parameter of this projection are NAME BANGLADESH TRANSVERSE MERCATOR (BTM) Projection Transverse_Mercator False_Easting 500000 False_Northing -2000000 Central_Meridian 90 Scale_Factor 0.9996 Latitude_Of_Origin 0 Linear Unit Meter (1.0) Geographic Coordinate System GCS_Everest_1830 Angular Unit Degree (0.0174532925199433) Prime Meridian Greenwich (0.0) Datum D_Everest_1830 Spheroid Everest_1830 Semimajor Axis 6377299.36 Semiminor Axis 6356098.35...
