# Module geodesicw

Wrapper around Python classes `geodesic.Geodesic` and `geodesicline.GeodesicLine` from Karney's Python package geographiclib, provided that package is installed.

The wrapped class methods return a GDict instance offering access to the `dict` items either by `key` or by `attribute` name.

With env variable `PYGEODESY_GEOGRAPHICLIB` left undefined or set to `"2"`, this module, pygeodesy.geodesicx and pygeodesy.karney will use GeographicLib 2.0 transcoding, otherwise `1.52` or older.

Version: 23.04.11

Functions
Geodesic(a_ellipsoid, f=None, name='') Return a wrapped `geodesic.Geodesic` instance from Karney's Python geographiclib, provide the latter is installed, otherwise an `ImportError`. |
GeodesicLine(geodesic, lat1, lon1, azi1, *caps) Return a wrapped `geodesicline.GeodesicLine` instance from Karney's Python geographiclib, provided the latter is installed, otherwise an `ImportError`. |
Geodesic_WGS84() Get the wrapped Geodesic`(WGS84)` singleton, provided geographiclib is installed, otherwise an `ImportError`. |

Function Details

### Geodesic (a_ellipsoid, f=None, name='') |
Return a wrapped `geodesic.Geodesic` instance from Karney's Python geographiclib, provide the latter is installed, otherwise an `ImportError`. Arguments: `a_ellipsoid` - An ellipsoid (Ellipsoid) or datum (Datum) or the equatorial radius a of the ellipsoid (`meter`). `f` - The flattening of the ellipsoid (`scalar`), ignored if `a_ellipsoid`) is not specified as `meter`. `name` - Optional ellipsoid name (`str`), ignored like `f`.

### GeodesicLine (geodesic, lat1, lon1, azi1, *caps) |
Return a wrapped `geodesicline.GeodesicLine` instance from Karney's Python geographiclib, provided the latter is installed, otherwise an `ImportError`. Arguments: `geodesic` - A wrapped Geodesic instance. `lat1` - Latitude of the first points (`degrees`). `lon1` - Longitude of the first points (`degrees`). `azi1` - Azimuth at the first points (compass `degrees360`). `caps` - Optional, bit-or'ed combination of Caps values specifying the capabilities the `GeodesicLine` instance should possess, i.e., which quantities can be returned by calls to `GeodesicLine.Position` and `GeodesicLine.ArcPosition`.
