================

.. py:module:: rhino3dm

.. py:class:: EarthAnchorPoint

   .. py:attribute:: EarthBasepointLatitude

      float: Gets or sets a point latitude on earth, in degrees.
      +90 = north pole, 0 = equator, -90 = south pole.

   .. py:attribute:: EarthBasepointLongitude

      float: Gets or sets the point longitude on earth, in degrees.

   .. py:attribute:: EarthBasepointElevation

      float: Gets or sets the point elevation on earth, in meters.

   .. py:attribute:: EarthBasepointElevationZero

      BasepointZero: Gets or sets a value indicating the zero level convention relating to a location on Earth.

   .. py:attribute:: ModelBasePoint

      rhino3dm.Point3d: Corresponding model point in model coordinates.

   .. py:attribute:: ModelNorth

      rhino3dm.Vector3d: Earth directions in model coordinates.

   .. py:attribute:: ModelEast

      rhino3dm.Vector3d: Earth directions in model coordinates.

   .. py:attribute:: Name

      str: Gets or sets the short form of the identifying information about this location.

   .. py:attribute:: Description

      str: Gets or sets the long form of the identifying information about this location.

   .. py:method:: EarthLocationIsSet()

      Checks if the earth location is set or not.

      :return: Boolean value, True if set else false

      :rtype: bool

   .. py:method:: GetModelCompass()

      Returns a plane in model coordinates whose X axis points East,
      Y axis points North and Z axis points Up. The origin
      is set to ModelBasepoint.

      :return: A plane value. This might be invalid on error.

      :rtype: rhino3dm.Plane

   .. py:method:: GetModelToEarthTransform(modelUnitSystem)

      Gets a transformation from model coordinates to earth coordinates.
      This transformation assumes the model is small enough that
      the curvature of the earth can be ignored.

      :param UnitSystem modelUnitSystem: The model unit system.

      :return: Transform on success. Invalid Transform on error.

      :rtype: Transform
