A local tangent plan LTP, a sub-class of `LocalCartesian` with configurable ECEF converter and without optional rotation matrix.

Method Details

### __init__ (self, latlonh0=0, lon0=0, height0=0, ecef=None, name='') (Constructor) |
New `Ltp`. Arguments: `latlonh0` - Either a `LatLon`, Ltp, Ecef9Tuple or `scalar` latitude of the (goedetic) origin (`degrees`). `lon0` - Optional `scalar` longitude of the (goedetic) origin for `scalar` `latlonh0` (`degrees`). `height0` - Optional origin height (`meter`), vertically above (or below) the surface of the ellipsoid. `ecef` - Optional ECEF converter (EcefKarney, l{EcefFarrell21}, EcefFarrell22, EcefSudano, EcefVeness or EcefYou instance), overriding default EcefKarney`(datum=Datums.WGS84)`. `name` - Optional name (`str`). Returns: New instance (`Ltp`). Raises: `LocalError` - If `latlonh0` not `LatLon`, Ecef9Tuple, `scalar` or invalid or if `lon0` not `scalar` for `scalar` `latlonh0` or invalid or if `height0` invalid. `TypeError` - Invalid `ecef`. Overrides: object.__init__

Property Details

### ecef Get this LTP's ECEF converter (`Ecef...` instance). Get method: ecef(self) - Get this LTP's ECEF converter (`Ecef...` instance). Set method: ecef(self, ecef) - Set this LTP's ECEF converter. Delete Method: _fdel(inst) - Zap the cached/memoized `property` value.
