Intersect tool for javascript

TimMcCurdy

Hello,

I am looking to work out the lengths of polyline (road) intersections on a polygon (user selection). It looks like something the Intersect tool would be perfect for, but I cannot find it for javascript.

Is this feature present for the javascript API? If not is there any plans to add it? Can it be emulated using code already in the API, or will I have to write my own?

Thanks
Tim

try the intersect method of the geometry task. we don't have any sample applications which call this method, but it would probably be helpful to check out our other geometry service samples here.

where I can review sample intersect method, I want to make a method that interceste a service layer and a point specified by the user

glad to hear it 🙂

Thanks that's what I was looking for. Didn't show up on a search.

Had to push all of my features into a geometry array for the input:

               if (identifyResults.length > 0) {
                  var geometryStack = [];
                  for (var k = 0; k < identifyResults.length; k++) {
                     geometryStack.push(identifyResults.feature.geometry);
                  }
                  var geoService = new esri.tasks.GeometryService("http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Geometry/GeometryServer");
                  geoService.intersect(geometryStack, geometry, onCompleteFunc, onErrorFunc);
