Constructors
| EPSG3857 | Creates a new instance of the EPSG3857 class. |
Properties
| Projection |
Gets the projection used by the CRS.
(Overrides CoordinateReferenceSystemProjection) |
| Transformation |
Gets the transformation used by the CRS.
(Overrides CoordinateReferenceSystemTransformation) |
Methods
| Distance |
Returns the distance, in meters, between two geographical coordinates.
(Inherited from Earth) |
| Equals | Determines whether the specified object is equal to the current object. (Inherited from Object) |
| Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object) |
| GetHashCode | Serves as the default hash function. (Inherited from Object) |
| GetType | Gets the Type of the current instance. (Inherited from Object) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object) |
| Scale |
Returns the scale used when transforming projected coordinates into
pixel coordinates for a particular zoom. For example, it returns
256 * 2^zoom for Mercator-based CRS.
(Inherited from CoordinateReferenceSystem) |
| ToString | Returns a string that represents the current object. (Inherited from Object) |
| Translate(GeoCoordinate, Double) |
Translates the given geographical coordinate
to a cartesian point at the given zoom level.
(Inherited from CoordinateReferenceSystem) |
| Translate(Point, Double) |
Translates the given cartesian point to a
geographical coordinate at the given zoom level.
(Inherited from CoordinateReferenceSystem) |
| Zoom |
Returns the zoom level corresponding to the given scale factor.
