Remarks

The result of a reprojection is a collection of features. Usually the collection will contain exactly one object which is a copy of the original feature, except that the geometry is defined in the target coordinate reference system specified.

The result can also be an empty list if the reprojection is not possible. For example, if the target Crs has an orthographic projection, which at most can show a single hemisphere, and the feature is located on the backside of the Earth. See the example maps on the OrthographicProjection page where the polygon representing Australia has disappeared.

The result can also contain two or more new features, which represent parts of the original one. For example, splitting occurs if the feature crosses the border of the visible hemisphere of an orthographic target, so that many distinct parts are visible. In the example maps shown on the OrthographicProjection page, the polygon for the entire American continent has been reprojected to two small parts. Also, splitting occurs if the feature crosses the interrupted meridian of a cylindrical target (LongLat, Mercator, Miller Cylindrical, or Equidistant Cylindrical); that is, the meridian that is antipodal to the central one. In the example map shown for Wgs84LongLat, you can see how the Russia polygon has been split along meridian 180°. Finally, splitting occurs if the feature crosses the interrupted half of the equator of a transverse cylindrical target. In the example map shown in on the TransverseMercatorProjection page, you can see how the Borneo polygon has been split along the equator. Its north half in the upper right corner, and its south half in the lower right corner.

Remarks

This method projects a feature into another coordinate reference system as ProjectTo but takes an additional ProjectParameters parameter that can be used to customize some aspects of the operation.
