Module css

Cassini-Soldner (CSS) projection.

Classes CassiniSoldner, Css and CSSError requiring Charles Karney's geographiclib Python package to be installed.

Version: 24.07.25

Classes

CSSError
Cassini-Soldner (CSS) conversion or other Css issue.

CassiniSoldner
Cassini-Soldner projection, a Python version of Karney's C++ class CassiniSoldner.

Css
Cassini-Soldner East-/Northing location.

EasNorAziRk4Tuple
4-Tuple (easting, northing, azimuth, reciprocal) for the Cassini-Soldner location with easting and northing in meters and the azimuth of easting direction and reciprocal of azimuthal northing scale, both in degrees.

EasNorAziRkEqu6Tuple
6-Tuple

(easting, northing, azimuth, reciprocal, equatorarc, 
        equatorazimuth)

for the Cassini-Soldner location with easting and northing in meters and the azimuth of easting direction, reciprocal of azimuthal northing scale, equatorarc and equatorazimuth, all in degrees.

LatLonAziRk4Tuple
4-Tuple (lat, lon, azimuth, reciprocal), all in degrees where azimuth is the azimuth of easting direction and reciprocal the reciprocal of azimuthal northing scale.

Functions

toCss(latlon, cs0=None, height=None, Css=<class 'pygeodesy.css.Css'>, **name)
Convert an (ellipsoidal) geodetic point to a Cassini-Soldner location.

Variables

__all__ = _ALL_LAZY.css

Function Details

toCss (latlon, cs0=None, height=None, Css=<class 'pygeodesy.css.Css'>, **name)

Convert an (ellipsoidal) geodetic point to a Cassini-Soldner location.

Arguments:

latlon - Ellipsoidal point (LatLon or LatLon4Tuple).
cs0 - Optional, the Cassini-Soldner projection to use (CassiniSoldner).
height - Optional height for the point, overriding the default height (meter).
Css - Optional class to return the location (Css) or None.
name - Optional Css name=NN (str).

Returns:

The Cassini-Soldner location (Css) or if Css is None, an EasNor3Tuple

(easting, northing, 
          height)

Raises:

CSSError - Ellipsoidal mismatch of latlon and cs0.
ImportError - Package geographiclib not installed or not found.
TypeError - If latlon is not ellipsoidal.
