Project a point to another spatial reference.
Use case
Being able to project between spatial references is fundamental in GIS. An example of when you would need to re-project data is if you had data in two different spatial references, but wanted to perform an intersect analysis with the
method. This method takes two geometries as parameters, and both geometries must be in the same spatial reference. If they are not, you could first use to convert the geometries so they match.How to use the sample
Tap anywhere on the map. A callout will display the tapped location’s coordinate in the original basemap’s spatial reference
and in the projected spatial reference .How it works
- Call the method, , passing in the original geometry and a spatial reference system to be projected to.

Additional information
In cases where the output spatial reference uses a different geographic coordinate system than that of the input spatial reference, see the
method that additionally takes in a parameter.Tags
