  • 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 one of the standard projections for British Columbia. It is also used by the United States Geological Survey and the United States Census Bureau. Snyder describes generating formulæ for the projection, as well as the projection's characteristics. Coordinates from a spherical datum can be transformed into Albers equal-area conic projection coordinates with the following formulas, where λ is the longitude, λ₀ the reference longitude, φ the latitude, φ₀ the reference latitude and φ₁ and φ₂ the standard parallels: where
