![]() Grids like this work best for determining the coordinates of a mark on the map. For example on a 1:24,000 scale USGS topo map the UTM grid lines are 1000m apart. But Datum for both projections is the same Ellipsoid, Everest. The UTM grid overlays are useful to interpolate one decimal place beyond the grid interval on the map. UTM maps are based on Cylindrical Projection while Lambert maps are based on Conical Projection. For nationwide coverage, (1134)map sheets at 1: 50,000 scale, (322)map sheets at 1: 100,000 scale and(93)map sheets at 1:250,000 scale were completely published. ![]() In such condition, UTM mapping system is suitable for Myanmar. Myanmar is a State where extent of North- South direction is larger than that of East-West direction. Topographic Maps that have been used since pre World War II time were based on Lambert Conical Projection.
