Azimuthal Equidistant

Options

Note

All options are optional for the Azimuthal Equidistant projection.

+guam

Use Guam elliptical formulas. Only accurate near the Island of Guam (\(\lambda\approx 144.5^{\circ}\), \(\phi\approx 13.5^{\circ}\))

+k_0=<value>

Scale factor. Determines scale factor used in the projection.

Defaults to 1.0.

+lat_ts=<value>

Latitude of true scale. Defines the latitude where scale is not distorted. Takes precedence over +k_0 if both options are used together.

Defaults to 0.0.

+lat_0=<value>

Latitude of projection center.

Defaults to 0.0.

+lon_0=<value>

Longitude of projection center.

Defaults to 0.0.

+x_0=<value>

False easting.

Defaults to 0.0.

+y_0=<value>

False northing.

Defaults to 0.0.

+ellps=<value>

See proj -le for a list of available ellipsoids.

Defaults to “WGS84”.

+R=<value>

Radius of the sphere given in meters. If used in conjunction with +ellps +R takes precedence.
