Module rd0

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

Version: 26.07.31

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.

Bounds4Tuple
4-Tuple (latS, lonW, latN, lonE) with the bounds' lower-left (LatS, LonW) and upper-right

(latN, 
        lonE)

corner lat- and longitudes.

LatLon2Tuple
2-Tuple (lat, lon) in degrees90 and degrees180.

LatLon3Tuple
3-Tuple (lat, lon, height) in degrees90, degrees180 and meter, conventionally.

LatLon4Tuple
4-Tuple (lat, lon, height, datum) in degrees90, degrees180, meter and Datum.

PhiLam2Tuple
2-Tuple (phi, lam) with latitude phi in radians[PI_2] and longitude lam in radians[PI].

PhiLam3Tuple
3-Tuple (phi, lam, height) with latitude phi in radians[PI_2], longitude lam in radians[PI] and height in meter.

PhiLam4Tuple
4-Tuple (phi, lam, height, datum) with latitude phi in radians[PI_2], longitude lam in radians[PI], height in meter and Datum.

Vector2Tuple
2-Tuple (x, y) of (geocentric) components, each in meter or the same units.

Vector3Tuple
3-Tuple (x, y, z) of (geocentric) components, all in meter or the same units.

LatLonN3Tuple
3-tuple (lat, lon, N) with geoid height N in meter, conventionally.

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).
