Method Details

### PointsIter (self, points, loop=0, dedup=False) |
Return a points iterator. Arguments: `points` - The path or polygon points (`LatLon`[]) `loop` - Number of loop-back points (non-negative `int`). `dedup` - Skip duplicate points (`bool`). Returns: A new `PointsIter` iterator. Raises: `PointsError` - Insufficient number of `points`.

### __init__ (self, lat, lon, name='', height=0, datum=None) (Constructor) |
Creat a new, mininal, low-overhead LatLon_ instance, without height and datum. Arguments: `lat` - Latitude (`degrees`). `lon` - Longitude (`degrees`). `name` - Optional name (`str`). `height` - Optional height (`float` or `int`). `datum` - Optional datum (Datum, Ellipsoid, Ellipsoid2, a_f2Tuple or scalar radius) or `None`. Raises: `TypeError` - Invalid `datum`. Overrides: object.__init__ Note: The lat- and longitude are taken as-given, un-clipped and un-validated .

### __repr__ (self) (Representation operator) |
repr(x) Overrides: object.__repr__ (inherited documentation)

### __str__ (self) (Informal representation operator) |
str(x) Overrides: object.__str__ (inherited documentation)

### classof (self, *args, **kwds) |
Instantiate this very class. Arguments: `args` - Optional, positional arguments. `kwds` - Optional, keyword arguments. Returns: New instance (`self.__class__`).

### copy (self, deep=False) |
Make a shallow or deep copy of this instance. Arguments: `deep` - If `True` make a deep, otherwise a shallow copy (`bool`). Returns: The copy (`This class` or subclass thereof).

### heightStr (self, prec=-2) |
Return a string for the height `height`. Arguments: `prec` - Optional number of decimals, unstripped (`int`). See Also: Function hstr.

### isequalTo (self, other, eps=None) |
Compare this point with an other point, ignoring height. Arguments: `other` - The other point (`LatLon`). `eps` - Tolerance for equality (`degrees`). Returns: `True` if both points are identical, ignoring height, `False` otherwise. Raises: `UnitError` - Invalid `eps`.

### others (self, *other, **name_other_up) |
Refined class comparison. Arguments: `other` - The other instance (any `type`). `name_other_up` - Overriding `name=other` and `up=1` keyword arguments. Returns: The `other` if compatible. Raises: `TypeError` - Incompatible `other` `type`.

### points (self, points, closed=False, base=None) |
DEPRECATED, use method `points2`. Decorators: `@deprecated_method`

### points2 (self, points, closed=False, base=None) |
Check a path or polygon represented by points. Arguments: `points` - The path or polygon points (`LatLon`[]) `closed` - Optionally, consider the polygon closed, ignoring any duplicate or closing final `points` (`bool`). `base` - Optionally, check all `points` against this base class, if `None` don't check. Returns: A Points2Tuple`(number, points)` with the number of points and the points `list` or `tuple`. Raises: `PointsError` - Insufficient number of `points`. `TypeError` - Some `points` are not `base`.

### to2ab (self) |
DEPRECATED, use property philam. Decorators: `@deprecated_method`

### toNvector (self, h=None, Nvector=<class 'pygeodesy.nvectorBase.NvectorBase'>, **Nvector_kwds) |
Convert this point to `n-vector` (normal to the earth's surface) components, including height. Arguments: `h` - Optional height, overriding this point's height (`meter`). `Nvector` - Optional class to return the `n-vector` components (`Nvector`) or `None`. `Nvector_kwds` - Optional, additional `Nvector` keyword arguments, ignored if `Nvector is None`. Returns: The `n-vector` components `Nvector` or if `Nvector` is `None`, a Vector4Tuple`(x, y, z, h)`. Raises: `TypeError` - Invalid `Nvector` or `Nvector_kwds` argument.

### toRepr (self, **kwds) |
This LatLon_ as a string "class(<degrees>, ...)". Arguments: `kwds` - Optional, keyword arguments. Returns: Class instance (`str`).

### toStr (self, form=`'``d``'`, prec=6, sep=', ', **kwds) |
This LatLon_ as a string "<degrees>, <degrees>". Arguments: `form` - Optional format, F_D, F_DM, F_DMS for deg°, deg°min′, deg°min′sec″ (`str`). `prec` - Optional number of decimal digits (0..8 or `None`). `sep` - Optional separator to join (`str`). `kwds` - Optional, keyword arguments. Returns: Instance (`str`).

### toStr2 (self, **kwds) |
DEPRECATED, used method toRepr. Decorators: `@deprecated_method`
