Fournier Projection

Classification

Pseudocylindrical

Identifier

fournier

Graticule

Meridians: Equally spaced elliptical curves converging at the poles.

Parallels: Straight lines.

Poles: Points.

Symmetry: About the Equator and central meridian.

Features

This projection is equal-area. Scale is constant along any parallel or pair of parallels equidistant from the Equator. This projection is neither equidistant nor conformal.

Parallels

There is no standard parallel for this projection.

Remarks

This projection was first described in 1643 by Georges Fournier. This is actually his second projection, the Fournier II.

Example

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