Map Projections Morph
This visualization shows some of the more common projections that SVS has encountered. Some of these projections have parameters that change the central point of the projection. In those cases, the parameters are animated and shown in the lower left.
Also included in this visualization are circles/ovals that are similar to "Tissot's Indicatrices". These are all circles of the same size on the spherical earth. Map projections distort them depending on the projection. The area of every circle is 1 million km² or about the size of Egypt. With each projection, the distortions of these circles show how shape and area are distorted in different parts of the projection.
The following projections are shown:
- polar stereographic
- lambert azimuthal
- albers equal area conic
- wrapped to a sphere
