Method Details

init (self, latlons, closed=False, radius=None, wrap=True)
(Constructor)

Handle LatLon points as pseudo-xy coordinates.

Arguments:

latlons - Points list, sequence, set, tuple, etc. (LatLon[]).
closed - Optionally, close the polygon (bool).
radius - Mean earth radius (meter).
wrap - If True, wrap or normalize and unroll the latlons points (bool).

Raises:

PointsError - Insufficient number of latlons.
TypeError - Some points are not base.

Overrides: object.__init__

Note: The LatLon latitude is considered the pseudo-y and longitude the pseudo-x coordinate, likewise for LatLon2Tuple. However, 2-tuples (x, y) are considered as (longitude, latitude).

contains (self, xy)
(In operator)

Check for a matching point.

Arguments:

xy - Point (LatLon, LatLon2Tuple or 2-tuple (x, y)) in (degrees.

Returns:

True if xy is present, False otherwise.

Raises:

TypeError - Invalid xy.

Overrides: _abcoll.Container.__contains__

getitem (self, index)
(Indexing operator)

Return the pseudo-xy or return a LatLon2psxy slice.

Overrides: _abcoll.Sequence.__getitem__

iter (self)

Yield all pseudo-xy's.

Overrides: _abcoll.Iterable.__iter__

len (self)
(Length operator)

Return the number of pseudo-xy's.

Overrides: _abcoll.Sized.__len__

repr (self)
(Representation operator)

Return a string representation.

Overrides: object.__repr__

reversed (self)

Yield all pseudo-xy's in reverse order.

Overrides: _abcoll.Sequence.__reversed__

str (self)
(Informal representation operator)

Return a string representation.

Overrides: object.__str__

count (self, xy)

Count the number of matching points.

Arguments:

xy - Point (LatLon, LatLon2Tuple or 2-tuple (x, y)) in (degrees.

Returns: integer

Count (int).

Raises:

TypeError - Invalid xy.

Overrides: _abcoll.Sequence.count

find (self, xy, *start_end)

Find the first matching point.

Arguments:

xy - Point (LatLon, LatLon2Tuple or 2-tuple (x, y)) in (degrees.
start_end - Optional [start[, end]] index (int).

Returns:

Index or -1 if not found (int).

Raises:

TypeError - Invalid xy.

findall (self, xy, *start_end)

Yield indices of all matching points.

Arguments:

xy - Point (LatLon, LatLon2Tuple or 2-tuple (x, y)) in (degrees.
start_end - Optional [start[, end]] index (int).

Returns:

Indices (iterator).

Raises:

TypeError - Invalid xy.

index (self, xy, *start_end)

Find the first matching point.

Arguments:

xy - Point (LatLon) or 2-tuple (x, y) in (degrees).
start_end - Optional [start[, end]] index (int).

Returns: integer

Index (int).

Raises:

IndexError - Point not found.
TypeError - Invalid xy.

Overrides: _abcoll.Sequence.index

point (self, ll)

Create a pseudo-xy.

Arguments:

ll - Point (LatLon).

Returns:

An Point3Tuple(x, y, ll).

Overrides: _Basequence.point

rfind (self, xy, *start_end)

Find the last matching point.

Arguments:

xy - Point (LatLon, LatLon2Tuple or 2-tuple (x, y)) in (degrees.
start_end - Optional [start[, end]] index (int).

Returns:

Index or -1 if not found (int).

Raises:

TypeError - Invalid xy.
