Apianus II Projection

Classification

Pseudocylindrical

Identifier

apianus

Graticule

Meridians: Equally spaced elliptical curves converging at the poles.

Parallels: Equally spaced straight lines.

Poles: Points.

Symmetry: About the Equator and central meridian.

Features

Scale is constant along any parallel or pair of parallels equidistant from the Equator, as well as along the central meridian. The Equator is free of angular distortion. This projection is not equal-area, equidistant, or conformal.

Parallels

There is no standard parallel for this projection.

Remarks

This projection was first described in 1524 by Peter Apian (or Bienewitz).

Limitations

This projection is available only on the sphere.

Example

landareas = shaperead('landareas.shp','UseGeoCoords',true);
axesm ('apianus', 'Frame', 'on', 'Grid', 'on');
geoshow(landareas,'FaceColor',[1 1 .5],'EdgeColor',[.6 .6 .6]);
