new GeographicProjection
A simple map projection where longitude and latitude are linearly mapped to X and Y by multiplying them by the Ellipsoid#getMaximumRadius. This projection is commonly known as geographic, equirectangular, equidistant cylindrical, or plate carrée. It is also known as EPSG:4326.
Parameters:
| Name | Type | Argument | Default | Description |
|---|---|---|---|---|
ellipsoid |
Ellipsoid |
<optional> |
Ellipsoid.WGS84 | The ellipsoid. |
Methods
-
getEllipsoid
-
Gets the Ellipsoid.
Returns:
Ellipsoid The ellipsoid. -
project
-
Projects a set of Cartographic coordinates, in radians, to map coordinates, in meters. X and Y are the longitude and latitude, respectively, multiplied by the maximum radius of the ellipsoid. Z is the unmodified height.
Parameters:
Name Type Argument Description cartographicCartographic The coordinates to project. resultCartesian3 <optional>
An instance into which to copy the result. If this parameter is undefined, a new instance is created and returned. Returns:
Cartesian3 The projected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned. -
unproject
-
Unprojects a set of projected Cartesian3 coordinates, in meters, to Cartographic coordinates, in radians. Longitude and Latitude are the X and Y coordinates, respectively, divided by the maximum radius of the ellipsoid. Height is the unmodified Z coordinate.
Parameters:
Name Type Argument Description cartesianCartesian3 The coordinate to unproject. resultCartographic <optional>
An instance into which to copy the result. If this parameter is undefined, a new instance is created and returned. Returns:
Cartographic The unprojected coordinates. If the result parameter is not undefined, the coordinates are copied there and that instance is returned. Otherwise, a new instance is created and returned.
