                                RDNAP2018v2

Transformer implementing RD NAP 2018 variant 2.

Note: Method RDNAP2018v2.reverse returns geodetic Bessel1841 (RD-Bessel) and not GRS80 (ETRS89) lat-/longitudes.

Instance Methods

__init__(self, a_ellipsoid=None, f=None, raiser=False, **name)
New RDNAP2018v1 or -v2 instance.

forward(self, lat, lon, height=0, raiser=None, name='forward')
Convert geodetic GRS80 (ETRS98) (lat, lon) and height to local (RDx, RDy) coordinates and NAPh quasi-geoid-height.

reverse(self, RDx, RDy, NAPh=0, raiser=None, **name)
Convert a local (RDx, RDy) point and NAPh height to geodetic Bessel1841 (RD-Bessel) (lat, lon, height).

similarity(self, **unused)
Get the forward or reverse datum transform, always None.

Method Details

init (self, a_ellipsoid=None, f=None, raiser=False, **name)
(Constructor)

New RDNAP2018v1 or -v2 instance.

Arguments:

a_ellipsoid - An ellipsoid (Ellipsoid), a datum (Datum) or the ellipsoid's equatorial radius (scalar, conventionally in meter), see f. Default Datums.GRS80.
f - The flattening of the ellipsoid (scalar) if a_ellipsoid is specified as scalar, ignored otherwise.
raiser - If True raise an RDNAPError for lat-/longitudes outside the RD region (bool).
name - Optional name (str).

Raises:

RDNAPError - Ellipsoid (or datum) is not oblate (i.e. is spherical or prolate) or the datum's transform is not unity.

Overrides: object.__init__

forward (self, lat, lon, height=0, raiser=None, name=`'forward'`)

Convert geodetic GRS80 (ETRS98) (lat, lon) and height to local (RDx, RDy) coordinates and NAPh quasi-geoid-height.

Arguments:

lat - Latitude (degrees geodetic).
lon - Longitude (degrees geodetic).
height - Height, optional (meter above geoid) or NAN to ignore NAPh interpolation.
raiser - If True raise an RDNAPError if lat or lon is outside the RD region (bool), if False don't, overriding property raiser.
name - Optional name='forward' (str).

Returns:

An RDNAP7Tuple

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

with local RDx, RDy coordinates and NAPh height.

Overrides: _RDNAPbase.forward

reverse (self, RDx, RDy, NAPh=0, raiser=None, **name)

Convert a local (RDx, RDy) point and NAPh height to geodetic Bessel1841 (RD-Bessel) (lat, lon, height).

Arguments:

RDx - Local RD X (meter, conventionally).
RDy - Local RD Y (meter, conventionally).
NAPh - NAP quasi-geoid-height (meter, conventionally) or NAN to ignore NAPh interpolation.
raiser - If True raise an RDNAPError if lat or lon is outside the RD region (bool), if False don't, overriding property raiser.
name - Optional name='reverse' (str).

Returns:

An RDNAP7Tuple

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

with geodetic lat and lon, height and datum Bessel1841 (RD-Bessel).

Property Details

variant

Get method:: _fget(inst) - Get the property value, only once and memoize/cache it.
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(*unused) - Silently ignored, always.
