AlbersProjection Class

The Albers projection: an equal-area conic projection, for the maps of a country or a continent. The distortion is smallest between its two standard parallels. The defaults are those of maps of the contiguous United States.

public sealed class AlbersProjection : GeoProjection

Remarks

The longitudes are measured from AlbersProjection.CentralMeridian: a region that spans the opposite meridian is cut in two, so use it for regional maps, not for world maps.
