In each of the corners of the map, two of the principle digits are expressed in their full UTM coordinate form. The red dot is found in the center of the grid defined by principle numbers 85 to 86 easting and 57 to 58 northing. It is possible to create maps that are somewhat equidistance. However, even these types of maps have some form of distance distortion. Equidistance maps can only control distortion along either lines of latitude or lines of longitude .
Distance is often correct on equidistance maps only in the direction of latitude.
An example of a large-scale map is a standard topographic map. On these maps measuring straight line distance is simple. Distance is first measured on the map using a ruler. This measurement is then converted into a real world distance using the map's scale. Thus, the actual distance in the real world would be 100,000 centimeters.
