.. _aeqd:
Azimuthal Equidistant Projection
================================
The shortest route from the center of the map
to any other point is a straight line in the azimuthal
equidistant projection.
So, for the specified point, all points that lie on a circle around
this point are equidistant on the surface of the earth on this projection.
The specified point ``lon_0, lat_0`` shows up as a black dot in the center of the map.
Here's an example using the width and height keywords to specify the map region.
.. plot:: source/users/figures/aeqd.py
If both the width/height and corner lat/lon keywords are omitted, the whole world is
plotted in a circle.
