An Azimuthal Equidistant projection

This projection provides accurate angles about and distances through the central position. Other angles, distances, or areas may be distorted.

Kwargs:

• central_longitude - The true longitude of the central meridian in

  degrees. Defaults to 0.

• central_latitude - The true latitude of the planar origin in

  degrees. Defaults to 0.

• false_easting - X offset from the planar origin in metres.

  Defaults to 0.

• false_northing - Y offset from the planar origin in metres.

  Defaults to 0.

• globe - An instance of cartopy.crs.Globe. If omitted, a

  default globe is created.

LambertConformal

class cartopy.crs.LambertConformal(central_longitude=-96.0, central_latitude=39.0, false_easting=0.0, false_northing=0.0, secant_latitudes=None, standard_parallels=None, globe=None, cutoff=-30)

A Lambert Conformal conic projection.

Kwargs:

• central_longitude - The central longitude. Defaults to 0.

• central_latitude - The central latitude. Defaults to 0.

• false_easting - X offset from planar origin in metres.

  Defaults to 0.

• false_northing - Y offset from planar origin in metres.

  Defaults to 0.

• standard_parallels - Standard parallel latitude(s).

  Defaults to (33, 45).

• globe - A cartopy.crs.Globe.

  If omitted, a default globe is created.

• cutoff - Latitude of map cutoff.

  The map extends to infinity opposite the central pole so we must cut off the map drawing before then. A value of 0 will draw half the globe. Defaults to -30.

• min_latitude - the maximum southerly extent of the projection.

  Defaults to -80 degrees.

• max_latitude - the maximum northerly extent of the projection.

  Defaults to 84 degrees.

RotatedPole

class cartopy.crs.RotatedPole(pole_longitude=0.0, pole_latitude=90.0, central_rotated_longitude=0.0, globe=None)

Defines a rotated latitude/longitude projected coordinate system with cylindrical topology and projected distance.

Coordinates are measured in projection metres.

Create a RotatedPole CRS.

The class uses proj4 to perform an ob_tran operation, using the pole_longitude to set a lon_0 then performing two rotations based on pole_latitude and central_rotated_longitude. This is equivalent to setting the new pole to a location defined by the pole_latitude and pole_longitude values in the GeogCRS defined by globe, then rotating this new CRS about it’s pole using the central_rotated_longitude value.

Args:

• pole_longitude - Pole longitude position, in unrotated degrees.

• pole_latitude - Pole latitude position, in unrotated degrees.

• central_rotated_longitude - Longitude rotation about the new

  pole, in degrees.

Kwargs:

• globe - An optional cartopy.crs.Globe.

  Defaults to a “WGS84” datum.
