```cs
public class EarthAnchorPoint : IDisposable
```

Contains information about the model's position in latitude, longitude, and elevation for GIS mapping applications.

## Constructors

- [EarthAnchorPoint](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/ctor.md): Initializes a new instance of the [EarthAnchorPoint](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint.md) class.

## Finalizer

- [~EarthAnchorPoint](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/finalize.md): Passively reclaims unmanaged resources when the class user did not explicitly call Dispose().

## Methods

- [Dispose](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/dispose.md): (2 overloads) Actively reclaims unmanaged resources that this instance uses.
- [EarthLocationIsSet](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/earthlocationisset.md): Checks if the earth location is set or not.
- [GetEarthAnchorPlane](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/getearthanchorplane.md): Returns the earth anchor plane
- [GetModelCompass](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/getmodelcompass.md): 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.
- [GetModelToEarthTransform](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/getmodeltoearthtransform.md): (2 overloads) 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.
- [ModelLocationIsSet](https://developer.rhino3d.com/api/rhinocommon/type/rhino.docobjects.earthanchorpoint/modellocationisset.md): Checks if the model location is set or not.
