reverse geocoding is always time out

ChiranjeeviGK · ‎01-23-2014

Hi

i am using Locator for geocoding as below

           this.locator = new Locator("http://geocode.arcgis.com/arcgis/rest/services/World/GeocodeServer");             //on(this.locator,"location-to-address-complete", lang.hitch(this,"_reverseGeocodingSuccess"));             //on(this.locator,"address-to-locations-complete", lang.hitch(this,"_geocodingSuccess"));

and i have added a click event listener as below

getAddress : function(/*Point*/ point)         {              this.locator.locationToAddress(webMercatorUtils.webMercatorToGeographic(point),100,              function(address){                 alert(address);             },function(err){                 alert(err);             });         },

Problem

always it says time out,

But from this example code its working fine
Locator sample

ChiranjeeviGK · ‎02-12-2014

in my code the event when the click is happen we have to pass the Point object to locator, with proper spatial reference

so in the code

on(map,"click",function(mapEvent){                 locator.locationToAddress(new Point(mapEvent.x,mapEvent.y),100);             });

we have to pass mapEvent.mapPoint which is having proper spatial reference

on(map,"click",function(mapEvent){                 locator.locationToAddress(mapEvent.mapPoint,100);             });

Will work..

Could your post or provide a link for your full code?

Error i can see is:

Oh I see. You're trying to use the x and y properties provided for your parameter. These are coordinates related to the screen position, not the map coordinates. Instead, use the mapPoint property that is already provided to you through your event params, like this:

on(map,"click",function(mapEvent){
    locator.locationToAddress(mapEvent.mapPoint,100);
});

If you're curious about the diferences in these units, take a look in the ScreenPoint documentation:

https://developers.arcgis.com/javascript/jsapi/screenpoint-amd.html

You can inspect the different values on your javascript console:

console.log(mapEvent.x);
console.log(mapEvent.y);
console.log(mapEvent.mapPoint.x);
console.log(mapEvent.mapPoint.y);

Let me know if this worked for you.

Regards.

This is probably happening because you're clicking on an point that don't have any street or geocode information on the specified range. You will always see this happening, for example, if you click on the ocean.

You'll find a message error explaining what's happening if you inspect the details array of your error object. Try to zoom in at the street level and click over one street. See if the error persists.

Take a look here too see it working.

in my code the event when the click is happen we have to pass the Point object to locator, with proper spatial reference

so in the code

on(map,"click",function(mapEvent){                 locator.locationToAddress(new Point(mapEvent.x,mapEvent.y),100);             });

we have to pass mapEvent.mapPoint which is having proper spatial reference

on(map,"click",function(mapEvent){                 locator.locationToAddress(mapEvent.mapPoint,100);             });

Will work..
