Large scale map projection (ca. 20 km) in pyproj results in wrong distance
Hiking & ActivitiesWhat does it mean when a map projection distorts the earth? A map that preserves shape is conformal. Even on a conformal map, shapes are a bit distorted for very large areas, like continents. A conformal map distorts area—most features are depicted too large or too small. The amount of distortion, however, is regular along
