Albers Equal Area Conic

The Albers Equal-Area Conic projection is a map projection in which the parallels are unequally spaced arcs of concentric circles spaced closer to each other near the north and south edges of the map. The meridians are equally spaced and intersect the parallels at right angles.

The Albers Equal-Area Conic projection is used for equal-area maps of regions with predominant east-west expanse, such as the United States. It is used exclusively by the USGS for sectional maps of all 50 states.

The "Albers Equal Area Conic" projection uses the following parameters:

• Northing at false origin

• Easting at False Origin

• Longitude of false origin

• Latitude of false origin

• Latitude of 1st standard parallel

• Latitude of 2nd standard parallel
