Geometry Service Project a point

CaseyBentz

I am trying to project an array of points from a custom coordinate system the web mercator.  I am using the geometry service project method and am coming up blank with how to set the input spatial reference for the geometries. The rest endpoint has a property for input spatial reference and output spatial reference, but the project parameters support class does not.

private function gpResult(event:GeoprocessorEvent):void{
 var geometriesToProject:Array = new Array();
                
 for each(var result:ParameterValue in event.executeResult.results){
  for each(var g:Graphic in result.value.features){
   geometriesToProject.push(g.geometry);                                
  }    
 }
 if(geometriesToProject.length > 0){
  var wkid:Number = 102100; 
  var projectionSR:SpatialReference = new SpatialReference(wkid);
  var projectParams:ProjectParameters = new ProjectParameters();
                    
  projectParams.geometries = geometriesToProject;
  projectParams.outSpatialReference = projectionSR;
  geometryService.project(projectParams);
 }
}

Casey,

   When ever I needed to use a WKT in a geometry service projection it has always worked fine. I do this in my Shapefile widget as there is now way to compare if a WKT from the shapes .prj file is the same as the maps WKID. This is what I am doing. Nothing real different from yours just less lines and if I don't have a WKTstr then just use the maps WKID.

const shpSpatialRef:SpatialReference = (WKTstr) ? new SpatialReference(Number.NaN, WKTstr) : map.spatialReference;
