Convert CLLocationCoordinate2D (geographic degrees WGS84) to UTM - wkID: 102100

Hi all

I am allowing users to collect points when they are offline using the iPhone GPS sensor. When users are back to online (3G or WIFI) the application has to load the points in an AGSMutable point and added to a FeatureService.

The issue is that I get geographic coordinates in degrees (WGS84) from CoreLocation and in order to add them to the Feature Service I need to convert them to UTM and Spatial Reference 102100.

Has somebody of you face this conversion?

Thanks in advance

Alberto

I think you can do it with AGSGeometryEngine's projectGeometry:toSpatialReference:

If you use self.mapView.gps.currentPoint then it'll be in map's spatial reference and not in WGS 1984.

Thanks a lot for your answers, solved it with self.mapView.gps.currentPoint
