                       Transform7Tuple

7-Tuple `(tx, ty, tz, s, sx, sy, sz)` Helmert transformation with translations `tx`, `ty` and `tz` in `millimeter`, scale `s` in `ppb` and rotations `sx`, `sy` and `sz` in `milliarcseconds`.

Method Details

### __new__ (cls, tx=0.0, ty=0.0, tz=0.0, s=0.0, sx=0.0, sy=0.0, sz=0.0, name='') Static Method |
New Transform7Tuple. Arguments: `tx` - Optional X translation (`millimeter`). `ty` - Optional Y translation (`millimeter`). `tz` - Optional Z translation (`millimeter`). `s` - Optional scale (`float`), ppb. `sx` - Optional X rotation (`milliarcseconds`). `sy` - Optional Y rotation (`milliarcseconds`). `sz` - Optional Z rotation (`milliarcseconds`). `name` - Optional name (`str`). Returns: a new object with type S, a subtype of T Raises: `LenError` - Unequal number of positional arguments and number of item `_Names_` or `_Units_`. `TypeError` - The `_Names_` or `_Units_` attribute is not a `tuple` of at least 2 items. `ValueError` - Item name is not a `str` or valid `identifier` or starts with `underscore`. Overrides: object.__new__

Class Variable Details

  ### _Names_ Tuple specifying the `name` of each `Named-Tuple` item. Note: Specify at least 2 item names. Value:
      ('tx', 'ty', 'tz', 's', 'sx', 'sy', 'sz')

  ### _Units_ Tuple defining the `units` of the value of each `Named-Tuple` item. Note: The `len(_Units_)` must match `len(_Names_)`. Value:
      (<class 'pygeodesy.units.Float'>,
       <class 'pygeodesy.units.Float'>,
       <class 'pygeodesy.units.Float'>,
       <class 'pygeodesy.units.Float'>,
       <class 'pygeodesy.units.Float'>,
       <class 'pygeodesy.units.Float'>,
       <class 'pygeodesy.units.Float'>)
