Classes L{RefFrame}, registry L{RefFrames} and L{TRFError}. Transcoded from I{Chris Veness'} (C) 2006-2022 JavaScript originals U{latlon-ellipsoidal-referenceframe.js<https://GitHub.com/ChrisVeness/geodesy/blob/master/ latlon-ellipsoidal-referenceframe.js>} and U{latlon-ellipsoidal-referenceframe-txparams.js <https://GitHub.com/ChrisVeness/geodesy/blob/master/latlon-ellipsoidal-referenceframe-txparams.js>}. Following is a copy of the comments in I{Veness}' U{latlon-ellipsoidal-referenceframe.js <https://GitHub.com/ChrisVeness/geodesy/blob/master/latlon-ellipsoidal-referenceframe.js>}. Modern geodetic reference frames: a latitude/longitude point defines a geographic location on, above or below the earth’s surface, measured in degrees from the equator and the U{International Reference Meridian<https://WikiPedia.org/wiki/IERS_Reference_Meridian>} (IRM) and metres above the ellipsoid within a given I{Terrestrial Reference Frame} at a given I{epoch}. This is scratching the surface of complexities involved in high precision geodesy, but may be of interest and/or value to those with less demanding requirements. More information U{here <https://www.Movable-Type.co.UK/scripts/geodesy-library.html>} and U{here <https://www.Movable-Type.co.UK/scripts/geodesy-library.html#latlon-ellipsoidal-referenceframe>}. Note that I{ITRF solutions} do not directly use an ellipsoid, but are specified by Cartesian coordinates. The GRS80 ellipsoid is recommended for transformations to geographical coordinates. Note WGS84(G730/G873/G1150) are coincident with ITRF at 10-centimetre level, see also U{here <ftp://ITRF.ENSG.IGN.Fr/pub/itrf/WGS84.TXT>}. WGS84(G1674) and ITRF20014 / ITRF2008 I{"are likely to agree at the centimeter level"}, see also U{QPS/Qinsy<https://Confluence.QPS.NL/qinsy/ en/how-to-deal-with-etrs89-datum-and-time-dependent-transformation-parameters-45353274.html>}. @var RefFrames.ETRF2000: RefFrame(name='ETRF2000', epoch=2005, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.GDA2020: RefFrame(name='GDA2020', epoch=2020, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.GDA94: RefFrame(name='GDA94', epoch=1994, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF2000: RefFrame(name='ITRF2000', epoch=1997, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF2005: RefFrame(name='ITRF2005', epoch=2000, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF2008: RefFrame(name='ITRF2008', epoch=2005, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF2014: RefFrame(name='ITRF2014', epoch=2010, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF90: RefFrame(name='ITRF90', epoch=1988, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF91: RefFrame(name='ITRF91', epoch=1988, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.ITRF93: RefFrame(name='ITRF93', epoch=1988, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.NAD83: RefFrame(name='NAD83', epoch=1997, ellipsoid=Ellipsoid(name='GRS80') @var RefFrames.WGS84: RefFrame(name='WGS84', epoch=1984, ellipsoid=Ellipsoid(name='WGS84') @var RefFrames.WGS84g1150: RefFrame(name='WGS84g1150', epoch=2001, ellipsoid=Ellipsoid(name='WGS84') @var RefFrames.WGS84g1674: RefFrame(name='WGS84g1674', epoch=2005, ellipsoid=Ellipsoid(name='WGS84') @var RefFrames.WGS84g1762: RefFrame(name='WGS84g1762', epoch=2005, ellipsoid=Ellipsoid(name='WGS84') ''' from pygeodesy.basics import map1, _xinstanceof from pygeodesy.datums import _ellipsoid, Transform from pygeodesy.ellipsoids import Ellipsoids, Fmt, Property_RO from pygeodesy.errors import _IsnotError, TRFError from pygeodesy.interns import NN, _COMMASPACE_, _cartesian_, _conversion_, \ _ellipsoid_, _ellipsoidal_, _epoch_, _exists_, \ _float as _F, _GRS80_, _NAD83_, _name_, _no_, _s_, \ _SPACE_, _sx_, _sy_, _sz_, _to_, _tx_, _ty_, _tz_, \ _WGS84_, _0_0, _0_001, _0_01, _0_1, _0_26, _0_5, _1_0 from pygeodesy.lazily import _ALL_LAZY from pygeodesy.named import classname, _lazyNamedEnumItem as _lazy, _NamedEnum, \ _NamedEnumItem, _NamedDict as _XD, _NamedTuple # from pygeodesy.props import Property_RO # from .ellipsoids # from pygeodesy.streprs import Fmt # from .ellipsoids from pygeodesy.units import Epoch, Float from math import ceil __all__ = _ALL_LAZY.trf __version__ = '22.05.12' _0_02 = _F( 0.02) _0_06 = _F( 0.06) _0_09 = _F( 0.09) _366_0 = _F(366) _mDays = (0, 31, 29, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31, 0) _ETRF2000_ = 'ETRF2000' _GDA2020_ = 'GDA2020' _GDA94_ = 'GDA94' _ITRF_ = 'ITRF' _ITRF88_ = 'ITRF88' _ITRF89_ = 'ITRF89' _ITRF90_ = 'ITRF90' _ITRF91_ = 'ITRF91' _ITRF92_ = 'ITRF92' _ITRF93_ = 'ITRF93' _ITRF94_ = 'ITRF94' _ITRF96_ = 'ITRF96' _ITRF97_ = 'ITRF97' _ITRF2000_ = 'ITRF2000' _ITRF2005_ = 'ITRF2005' _ITRF2008_ = 'ITRF2008' _ITRF2014_ = 'ITRF2014' _WGS84g1150_ = 'WGS84g1150' _WGS84g1674_ = 'WGS84g1674' _WGS84g1762_ = 'WGS84g1762' class RefFrame(_NamedEnumItem): '''Terrestrial Reference Frame (TRF) parameters.
