Method Project
Project(Geometry, SpatialReference)
Projects the given geometry from its current spatial reference system into the given spatial reference system.
Declaration
public static Geometry Project(this Geometry geometry, SpatialReference outputSpatialReference)Parameters
| Type | Name | Description |
|---|---|---|
| Geometry | geometry | The geometry to be projected. |
| SpatialReference | outputSpatialReference | The spatial reference to which geometry need to be projected. |
Returns
| Type | Description |
|---|---|
| Geometry | The geometry projected into the given SpatialReference. If the input
geometry has a |
Remarks
A default best-choice DatumTransformation is applied to the project operation. To control the specific transformation used, use the Project(Geometry, SpatialReference, DatumTransformation) overload.
If the geometry parameter has z-values, those z-values are also be transformed,
if both the SpatialReference of that geometry, and the
outputSpatialReference parameter, have a vertical coordinate system.
Supports true curves. Projecting curves located at poles and coordinate system horizons using this API may give results that differ slightly from other ArcGIS software because it uses a different geometry projection function.

Project(Geometry, SpatialReference, DatumTransformation)
Projects the given geometry from its current spatial reference system into the given output spatial reference system, applying the datum transformation provided.

Remarks
Use this overload to project a geometry if the difference between the input geometry's
SpatialReference and the outputSpatialReference involves
a change of datum, and you do not wish to use the default datum transformation used by
Project(Geometry, SpatialReference).
Using a HorizontalVerticalTransformation also transforms the
z-values of the geometry (if the geometry has them) if both the SpatialReference
of the geometry and the outputSpatialReference have a vertical coordinate system set.
Supports true curves. Projecting curves located at poles and coordinate system horizons using this API may give results that differ slightly from other ArcGIS software because it uses a different geometry projection function.
