EarthAnchorPoint
ReferencesContains information about the model's position in latitude, longitude, and elevation for GIS mapping applications.
Constructors
public EarthAnchorPoint()
Initializes a new instance of the EarthAnchorPoint class.
Finalizer
~EarthAnchorPoint
#~EarthAnchorPoint()
Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().
Properties
Gets or sets the long form of the identifying information about this location.
Gets or sets the point elevation on earth, in meters.
Gets or sets a value indicating the zero level convention relating to a location on Earth.

obsoletePlease use EarthBasepointElevationCoordinateSystem property
Gets or sets a value indicating the zero level convention relating to a location on Earth.
Gets or sets a point latitude on earth, in degrees. +90 = north pole, 0 = equator, -90 = south pole.
Gets or sets the point longitude on earth, in degrees.
Gets Keyhole Markup Language (KML) orientation heading angle in degrees.
Gets Keyhole Markup Language (KML) orientation heading angle in radians.
Gets Keyhole Markup Language (KML) orientation roll angle in degrees.
Gets Keyhole Markup Language (KML) orientation roll angle in degrees.
Gets Keyhole Markup Language (KML) orientation tilt angle in degrees.
Gets Keyhole Markup Language (KML) orientation tilt angle in degrees.
Corresponding model point in model coordinates.
Methods
public void Dispose()
Actively reclaims unmanaged resources that this instance uses.
Dispose
#For derived class implementers.
This method is called with argument true when class user calls Dispose(), while with argument false when the Garbage Collector invokes the finalizer, or Finalize() method.
You must reclaim all used unmanaged resources in both cases, and can use this chance to call Dispose on disposable fields if the argument is true.
Also, you must call the base virtual method within your overriding method.
Parameters:
| disposing (bool) | true if the call comes from the Dispose() method; false if it comes from the Garbage Collector finalizer. |
Checks if the earth location is set or not.
Returns: Boolean value, true if set else false
Returns the earth anchor plane
Parameters:
| anchorNorth (out Vector3d) |
Returns: A plane value.
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.
Returns: A plane value. This might be invalid on error.
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.
Remarks: If M is a point in model coordinates and E = model_to_earth*M, then E.x = latitude in decimal degrees E.y = longitude in decimal degrees E.z = elevation in meters above mean sea level Because the earth is not flat, there is a small amount of error when using a linear transformation to calculate oblate spherical coordinates. This error is small. If the distance from P to M is d meters, then the approximation error is latitude error <= longitude error <= elevation error <= 6379000*((1 + (d/6356000)^2)-1) meters In particular, if every point in the model is within 1000 meters of the m_model_basepoint, then the maximum approximation errors are latitude error <= longitude error <= elevation error <= 8 centimeters.
Parameters:
| modelUnits (LengthUnit) | The model length unit. |
Returns: Transform on success. Invalid Transform on error.
