                                        LqRD

Like pygeodesy.LqRD but with methods forward and reverse returning an RDNAP7Tuple with NAPh replaced by local z, the perpendicular distance to the local tangent plane (LTP).

This quasi-RD transformer does not implement any RD NAP specification and does not provide Netherlands' Normaal Amsterdams Peil (NAP) quasi-geodetic-height.

Instance Methods

forward(self, lat_latlonh, lon=None, height=0, **name)
Convert geodetic (lat, lon, height) to local quasi-RD (x, y, z).

reverse(self, x_xyz, y=None, z=None, **name)
Convert local quasi-RD (x, y, z) to geodetic (lat, lon, height).

Method Details

forward (self, lat_latlonh, lon=None, height=0, **name)

Convert geodetic (lat, lon, height) to local quasi-RD (x, y, z).

Arguments:

lat_latlonh - Scalar (geodetic) latitude (degrees) or a local quasi-RD RDNAP7Tuple.
lon - Scalar (geodetic) longitude (degrees) iff lat_latlonh is scalar, ignored otherwise.
height - Optional height (meter, conventionally) perpendicular to and above (or below) the ellipsoid's surface, iff lat_latlonh is scalar, ignored otherwise.
name - Optional name=NN (str).

Returns:

An RDNAP7Tuple

(RDx, RDy, NAPh, lat, lon, 
          height, datum)

with NAPh set to local z.

Raises:

LocalError - If latlonh not scalar, LatLon, Ltp, Ecef9Tuple or invalid or if lon not scalar for scalar latlonh or invalid or if height invalid.

Overrides: pygeodesy.ltp.LocalCartesian.forward

See Also: pygeodesy.LqRD.forward for more information.

reverse (self, x_xyz, y=None, z=None, **name)

Convert local quasi-RD (x, y, z) to geodetic (lat, lon, height).

Arguments:

x_xyz - Local quasi-RD x coordinate (scalar) or a local quasi-RD RDNAP7Tuple.
y - Local quasi-RD y coordinate (meter) iff x_xyz is scalar, ignored otherwise.
z - Local z coordinate (meter) iff x_xyz is scalar, ignored otherwise.
name - Optional name=NN (str).

Returns:

An RDNAP7Tuple

(RDx, RDy, NAPh, lat, lon, 
          height, datum)

with NAPh set to local z.

Raises:

LocalError - Invalid xyz or scalar x or y and/or z not scalar for scalar xyz.

Overrides: pygeodesy.ltp.LocalCartesian.reverse
