Method Details

init (self, latlonh, lon=None, height=0, wrap=False, name='', datum=None)
(Constructor)

New LatLon_.

Arguments:

latlonh - Latitude (degrees or DMS str with N or S suffix) or a previous LatLon instance provided lon=None.
lon - Longitude (degrees or DMS str with E or W suffix) or C(None), indicating latlonh is a LatLon.
height - Optional height above (or below) the earth surface (meter, conventionally).
wrap - If True, wrap or normalize lat and lon (bool).
name - Optional name (str).
datum - Optional datum (Datum, Ellipsoid, Ellipsoid2, a_f2Tuple or scalar radius) or None.

Returns:

New instance (LatLon).

Raises:

RangeError - A lon or lat value outside the valid range and rangerrors set to True.
TypeError - If latlonh is not a LatLon.
UnitError - Invalid lat, lon or height.

Overrides: object.__init__

Note: The lat- and longitude values are taken as-given, un-clipped and un-validated.

See Also: latlonBase.LatLonBase for further details.

eq (self, other)
(Equality operator)

Overrides: latlonBase.LatLonBase.__eq__

ne (self, other)

Overrides: latlonBase.LatLonBase.__ne__

intermediateTo (self, other, fraction, height=None, wrap=False)

Locate the point at a given fraction, linearly between (or along) this and an other point.

Arguments:

other - The other point (LatLon).
fraction - Fraction between both points (float, 0.0 for this and 1.0 for the other point).
height - Optional height (meter), overriding the intermediate height.
wrap - If True, wrap or normalize and unroll the other point (bool).

Returns:

Intermediate point (this LatLon).

Raises:

TypeError - Incompatible other type.

toRepr (self, **kwds)

This LatLon_ as a string "class(<degrees>, ...)", ignoring keyword argument std=N/A.

Arguments:

kwds - Optional, toStr keyword arguments.

Returns:

toStr() with keyword arguments (as str).

Overrides: named._Named.toRepr

See Also: latlonBase.LatLonBase.toRepr for further details.

toStr (self, form=`'d'`, joined=', ', **m_prec_sep_s_D_M_S)

Convert this point to a "lat, lon[, height][, name][, ...]" string, formatted in the given format.

Arguments:

form - The lat-/longitude format to use (str), see functions pygeodesy.latDMS or pygeodesy.lonDMS.
joined - Separator to join the lat-, longitude and heigth strings (str or None or NN for non-joined).
m - Optional unit of the height (str), use None to exclude height from the returned string.
prec_sep_s_D_M_S - Optional precision, separator, s_D, s_M, s_S and s_DMS keyword arguments, see function pygeodesy.latDMS or pygeodesy.lonDMS.

Returns:

This point in the specified format, etc. (str or a 2- or 3-tuple

(lat_str, lon_str[, 
          height_str])

if joined=NN or joined=None).

Overrides: named._Named.toStr

See Also: latlonBase.LatLonBase.toStr for further details.

Property Details

datum

Get the datum (Datum) or None.

Get method:: datum(self) - Get the datum (Datum) or None.
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst) - Zap the cached/memoized property value.
