Package pyrdnap :: Module rd0

Module rd0

(INTERNAL) RijksDriehoeksmeting _RD and reference _RD0 constants and classes RDNAP7Tuple and LqRD.

Version: 26.08.18

Classes
	Datum Ellipsoid and transform parameters for an earth model.
	Similarity Similarity transformation.
	Ellipsoid Ellipsoid with equatorial and polar radii, flattening, inverse flattening and other, often used, cached attributes, supporting oblate and prolate ellipsoidal and spherical earth models.
	RDNAP7Tuple 7-Tuple `(RDx, RDy, H, lat, lon, height, datum)` with local `RDx`, `RDy` and (orthometric) height `H`, geodetic `lat`, `lon`, (ellipsoidal) `height` and `datum` with `lat` and `lon` in `degrees` and with `RDx`, `RDy`, `H` and `height` in `meter`, conventionally.
	LqRD Like pygeodesy.LqRD but with methods `forward` and `reverse` returning an RDNAP7Tuple with `H` replaced by local `z`, the perpendicular distance to the local tangent plane (LTP).
	RDxyHeight3Tuple 3-tuple `(RDx, RDy, H)` with orthometric height `H`, all in `meter`.
	RDxyheight3Tuple 3-tuple `(RDx, RDy, h)` with ellipsoidal height `h`, all in `meter`.
	RDxyNgeoid3Tuple 3-tuple `(RDx, RDy, N)` with geoid height `N`, all in `meter`.
