Package gavo :: Package stc :: Module geo

Module geo

Coordinate systems for positions on earth.

Classes
	WGS84 the WGS84 reference system.

Functions

geocToGeod(long, phip, rho=1, refSys=<class 'gavo.stc.geo.WGS84'>)
returns geodetic coordinates long, phi for geocentric coordinates.

source code

geodToGeoc(long, phi, height, refSys=<class 'gavo.stc.geo.WGS84'>)
returns geocentric coordinates lambda, phi', rho for geodetic coordinates.

Variables
	__package__ = `'gavo.stc'`

Function Details

returns geodetic coordinates long, phi for geocentric coordinates.

refSys defaults is the reference system the geodetic coordinates are expressed in.

This will not work at the poles -- patches welcome.

See Astron. Almanac, Appendix K; we go for the iterative solution discussed there.

returns geocentric coordinates lambda, phi', rho for geodetic coordinates.

refSys defaults is the reference system the geodetic coordinates are expressed in.

height is in meter, long, phi in degrees.
