Method Details

### __init__(self, x, y, z, h=0, ll=None, name=`'````'`) (Constructor) |
New n-vector normal to the earth's surface. Parameters: `x` - X component (`scalar`). `y` - Y component (`scalar`). `z` - Z component (`scalar`). `h` - Optional height above surface (`meter`). `ll` - Optional, original latlon (`LatLon`). `name` - Optional name (`str`). Overrides: object.__init__ Example:
    >>> from sphericalNvector import Nvector
    >>> v = Nvector(0.5, 0.5, 0.7071, 1)
    >>> v.toLatLon()  # 45.0°N, 045.0°E, +1.00m

### copy(self) |
Copy this vector. Returns: The copy (Nvector or subclass thereof). Overrides: bases.Named.copy

### to3abh(self) |
Convert this n-vector to (geodetic) lat-, longitude and height. Returns: 3-Tuple (lat, lon, height) in (`radians`, `radians`, `meter`).

### to3llh(self) |
Convert this n-vector to (geodetic) lat-, longitude and height. Returns: 3-Tuple (lat, lon, height) in (`degrees90`, `degrees180`, `meter`).

### to4xyzh(self) |
Return this n-vector as a 4-tuple. Returns: 4-Tuple (x, y, z, h) in (`meter`).

### toStr(self, prec=5, fmt=`'``(%s)``'`, sep=`'``,` `'`) |
Return a string representation of this n-vector. Height component is only included if non-zero. Parameters: `prec` - Optional number of decimals, unstripped (`int`). `fmt` - Optional enclosing backets format (`str`). `sep` - Optional separator between components (`str`). Returns: Comma-separated "x, y, z [, h]" (`str`). Overrides: bases.Based.toStr Example:
    >>> Nvector(0.5, 0.5, 0.7071).toStr()  # (0.5, 0.5, 0.7071)
    >>> Nvector(0.5, 0.5, 0.7071, 1).toStr(-3)  # (0.500, 0.500, 0.707, +1.00)

### toVector3d(self) |
Convert this n-vector to a normalized 3-d vector, ignoring the height. Returns: Normalized vector (Vector3d).

### unit(self, ll=None) |
Normalize this vector to unit length. Parameters: `ll` - Optional, original latlon (`LatLon`). Returns: Normalized vector (Nvector). Overrides: vector3d.Vector3d.unit

Property Details

### h Get the height above surface (`meter`). Get Method: h(self) - Get the height above surface (`meter`). Set Method: h(self, h) - Sets height above surface.
