Hi Forum, Thanks for supporting to me, I just solved the problem this one was made by using esri.geometry.geographicToWebMercator( shape ) The better for you. Carlos Can you post a screen shot of what your data looks like when added to a Google map? Posting the code to do so would also be helpful. One thing I'd like to point out is that your data is in geographic coordinates (latitude and longitude) but you're probably using web mercator basemaps. We plan to simplify this, but until we do, you need to convert your geographic data to web mercator. You can use esri.geometry.geographicToWebMercator to do this. Regarding specific support for multipolygons in the JS API, yes, they are supported. See a previous discussion I participated in on gis.stackexchange: Esri JSON Polygon Ring Orientation.

Hi Forums Team, I am going to review the info related to WebMercator, because my code is not using that. Any ways if you can send me an example about how to adjust that into my code , it will be very appreciated. I attach the information requested. 1. The screenshot of the map plotted on google map which works fine. 2. The source code in order to see if I am making a mistake. ( I just probed using differents wkid: 102100 and 4326 ) I am really happy by using ArcGIS but I would like to complete that to show the work and let know to my friends and coworkers about the benefits by using ArcGIS. thanks in advance.

Hi everyone!, I am newbie working on ArcGIS, I was working with google maps days ago but I came across with the need to apply new feaute which Google Maps does not have. So I migrated my project to ArcGIS. But Unfourtunally I got a problem: 1. I am trying to show polygons from JSON data. but no shape appear. The same JSON data from Google Maps is show. 2. I copy the JSON structure over an online Geometry Visualizer tool in order to find any problem, but the same problem persists no shape is shown neither. Please, anyone may help me ASAP about this issue? what is the different between Google Maps and ArcGIS why does it work for one YES and the another NO ?? I attached JSON data as a zip file. Thanks in advance! Carlos
