This projection was developed to provide a conformal map of Alaska with less scale distortion than other conformal projections. A set of mathematical formulas defines a conformal transformation between two surfaces (Snyder, 1993).
Modified planar. This is a sixthorder equation modification of an oblique Stereographic conformal projection on the Clarke 1866 spheroid. The origin is at 64° N, 152° W.
Conceptual point of tangency at 64° N, 152° W.
None
Distortion becomes severe away from Alaska.
Conformal mapping of Alaska as a complete state on the Clarke 1866 spheroid or NAD27. This projection is not optimized for use with other datums and spheroids.
Projectionspecific parameters are set by the software.
