Dear Mr Owen, Any solution regarding this problem? Thanks in advance.

Dear Owen, Thanks for your replay, i hope you spend an amazing holiday Actually the objective from having the polygon ID is to have control on it and delete some polygons when we have intersection. Below the steps regarding the scenario. Scenario: - Keep the first one. - Check the second one if intersect delete the second if not keep it. - Check the third one if intersect delete if not keep it. - ... I update the Javascript code using service network area for arcgis online that you can test the result (Working but not deleting the intersection) the problem is i don't know how to check the intersection and deleted from the list. I am using ESRI services you can run the application in your computer in order to check. The part regarding the intersection is mentioned in a commentaire.

Dear Josh, Thank you very very very very very much, you support is very helpful. After looking at the link you send me i think this could be the solution, i didn't know how to move from the existing code to the one you gave me. If you can help me i will be very grateful to you. You can test the code i'am using esri services Thank you a lot in advance.

Dear Josh, Thanks a lot for your replay and your help. Regarding the second proposition, it's not a problem for our solution the objective is to delete the polygon if it intersect with another one. The only part that i believe is messing is when i mentioned in the code : Delete from polys list all polygons that intersect with polys[index] when we delete a polygon from polys -> index--; That part i really don't know how to do it, the code i gave can be run in your machine in order to test (I am using ArcGIS Online services from ESRI) Your support is very helpful Thanks you very much.

Dear Owen, I tried this code to verify if two polygons intersect or not? I changed this part dojo.forEach(solveResult.serviceAreaPolygons, function(serviceArea){ by the code below. It's not working you can have a look on it please. var polys = solveResult.serviceAreaPolygons; for(var i=0; i<polys.length; i++) { // Collect point of the first polygon from the feature list pointPoly = features[polys["attributes"]["facilityId"] - 1] for(var j=i+1; j<polys.length; j++) { // Verify if the polygon polys intersect pointPoly var test = intersect(polys , pointPoly); function intersectionPolygons(polys , pointPoly) { // if yes if(test = true) { // Deleate the polygon from the list polys.splice(j,1); // Reduce the values due to size change in the index table j--; i--; } } // else go to the next iteration } } I really need it urgent thanks a lot for your support

Sorry for the delay of my answer i was sick I am already using a geometry service, and now i know that each polygon have a Id. What i want to do is to keep the first polygon and check the second one if it intersect with the first one i will keep it otherwise i will delete that polygon and go to the next one. This task i really don't know how to proceed if some you can help i will be very greatfull

‎12-17-2014

Thank you for you replay But can i check if two polygon (Drive time polygon) intersect if i use point ID?

‎12-17-2014

Dear Mr Owen, Thank you very much for your replay. Your answer is very helpful. Can i have a control of that Polygon Id because i have to keep only points when polygon do not intersect. Exemple I will keep the first point polygon and add the second one if the polygon of the second one intersect with the first one i delete the second one and go to the other one. Now in the console i am having the same result but i don't know if i can do intersect query on that polygon ?

Dear All, I create a prototype which add a group of point to the map and create the drive time polygon around each point (Based on service area sample). The prototype is creating the polygons in the same time but i cannot control each polygon separately, i would like to create an Id for each polygon created around each point so i can use them for other query like polygon intersect ... Below the code i create if anyone can help i will be grateful: <!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8"> <meta http-equiv="X-UA-Compatible" content="IE=7, IE=9, IE=10">  <meta name="viewport" content="initial-scale=1, maximum-scale=1,user-scalable=no"> <title>Dispatch Algorithm Implementation</title> <link rel="stylesheet" href="http://js.arcgis.com/3.9/js/dojo/dijit/themes/claro/claro.css"> <link rel="stylesheet" href="http://js.arcgis.com/3.9/js/esri/css/esri.css"> <style> body,html,#main{margin:0;padding:0;height:100%;width:100%;} </style> <script>var dojoConfig = { parseOnLoad: true };</script> <script src="http://js.arcgis.com/3.9/"></script> <script> dojo.require("esri.map");

Dear Heiko, Thanks for your replay. I already try that but this will run the area service by click on the map not after a button click. The "AddDTP" is to use the button click, in the body of my code i have: <button onclick="AddDTP();">Test</button> So i want to run the task after a button click your solution will give me the possibility to run it by map click.
