Small scale maps have distortions
WebDec 19, 2024 · Conic projections are good for small-scale maps such as road maps. How can a map be misleading? Flattening Earth’s image requires that parts of it be extensively stretched, in width and height, resulting in four highly significant distortions: size, shape, direction and distance. WebA conformal projection will have distortion ellipses that vary substantially in size, but are all the same circular shape. The consistent shapes indicate that conformal projections (like this Mercator projection of the world) preserve shapes and angles.
