cartopy.geodesic.Geodesic¶
- class cartopy.geodesic.Geodesic(radius=6378137.0, flattening=0.0033528106647474805)[source]¶
Define an ellipsoid on which to solve geodesic problems.
- __init__(radius=6378137.0, flattening=0.0033528106647474805)[source]¶
- Parameters
radius (float, optional) – Equatorial radius (metres). Defaults to the WGS84 semimajor axis (6378137.0 metres).
flattening (float, optional) – Flattening of ellipsoid. Setting flattening = 0 gives a sphere. Negative flattening gives a prolate ellipsoid. If flattening > 1, set flattening to 1/flattening. Defaults to the WGS84 flattening (1/298.257223563).
Methods
__init__([radius, flattening])- param radius
Equatorial radius (metres). Defaults to the WGS84 semimajor axis
circle(lon, lat, radius[, n_samples, endpoint])Find a geodesic circle of given radius at a given point.
direct(points, azimuths, distances)Solve the direct geodesic problem where the length of the geodesic is specified in terms of distance.
geometry_length(geometry)Return the distance (in physical meters) of the given Shapely geometry.
inverse(points, endpoints)Solve the inverse geodesic problem.
