Syntax
public class AlbersEqualAreaConicProjection : ProjectionRemarks
This map projection, presented by Heinrich Christian Albers in 1805, is equal-area, and has true scale on its two standard parallels. Between the standard parallels, features appear too tall and narrow. Outside the standard parallels, features appear too short and fat. (Small features near a standard parallel nearly keep their true shape.)
The projection is used for medium-scale and small-scale maps (showing continents and large countries) that should be equal-area.
