Lambert Azimuthal Equal Area Projection

The Lambert azimuthal equal-area projection is a map projection used in cartography. It accurately represents area in all regions of the sphere, but it does not accurately represent angles. The Lambert azimuthal equal-area projection is used for navigation, thematic and USGS maps.

Azimuthal equal-area projections are able to present the whole Earth in a single map and with constant radial scale (distances increase linearly from the center of projection). Like the superficially similar azimuthal equidistant, the Lambert azimuthal projection strongly distorts shapes in the boundary of a worldwide map. However, the radial scale is not constant: in the polar aspect, parallels (circles of latitude) get closer together towards the border, just enough to preserve areas.
