Albers projection

(mapping) An equal-area projection of the conical type, on which the meridians are straight lines that meet in a common point beyond the limits of the map, and the parallels are concentric circles whose center is at the point of intersection of the meridians.

An Albers projection shows areas accurately, but distorts shapes.

The Albers equal-area conic projection, or Albers projection, is a conic, equal area map projection that uses two standard parallels. Although scale and shape are not preserved, distortion is minimal between the standard parallels.

The Albers projection is the standard projection for British Columbia.^[1] It is also used by the United States Geological Survey and the United States Census Bureau.^[2]
