Class Numpy2LatLon

Handle a NumPy array as a sequence of LatLon points.

Arguments:

• array - NumPy array (numpy.array).
• ilat - Optional index of the latitudes column (int).
• ilon - Optional index of the longitudes column (int).
• LatLon - Optional LatLon class to use (LatLon_).

Raises:

• IndexError - If array.shape is not (1+, 2+).
• TypeError - If array is not a NumPy array or LatLon is not a class with lat and lon attributes.
• ValueError - If the ilat and/or ilon values are the same or out of range.

Overrides: object.__init__

>>> type(array)
<type 'numpy.ndarray'>  # <class ...> in Python 3+
>>> points = Numpy2LatLon(array, lat=0, lon=1)
>>> simply = simplifyRDP(points, ...)
>>> type(simply)
<type 'numpy.ndarray'>  # <class ...> in Python 3+
>>> sliced = points[1:-1]
>>> type(sliced)
<class '...Numpy2LatLon'>
