Method Details

### __init__ (self, array, ilat=0, ilon=1, LatLon=None) (Constructor) |
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__ Example:
    >>> 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'>

### isNumpy2 Is this a Numpy2 wrapper? Get method: isNumpy2(self) - Is this a Numpy2 wrapper? Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.
