Thanks!!!

Hi Davide,

Technically, it is possible to embed Google Maps data into the Viewer. However, from a legal/licensing standpoint the answer is a little more complicated.

Please see this great blog post from Rex Hansen (of the ArcGIS API for Silverlight Dev team) on the topic:
Using Google Maps with ArcGIS Silverlight

Hope this helps,

Hi Derek,
Thank you for your reply!

The solution proposed in the Rex Hansen article is very interesting and useful for mobile applications but too limited for a web application (ex. image size 640 x 640) as he highlighted in his article.

What about the use of ArcGIS JavaScript Extension for Google Maps to take advantage of interoperability provided by this API? This is certainly legal. But possible?

Thank you!!!!

Hi Davide,

The ArcGIS JavaScript Extension for Google Maps does work with Google Maps data, but can't really be integrated within the ArcGIS Viewer for Flex.

Hope this helps,

if you want to see a sample application you can look at the http://www.cbsmerkezi.com/esrigoogle. But I dont know anythink about licensing constraints for usage of google maps api.

Hello, if he could take over the project . Simply can not find the path to the google map server.
If you have any ideas, please let me know ....

Thanks

there is no problem for google map server. if you using a gmaps map object on
http://example/project/gmapobject.html you must get google api key for http://example/project
or I cant understand you 🙂

Well, i'm not able to share the whole project with you but i can mention about how it is done. There exist two map objects in a canvas which Esri map object is over the Google map object. Any extend modification of the Esri map object updates the Google map object, too. To provide these extend transformations, you can use Esri' s project method of geometry service and WebMercatorUtil.geographicToWebMercator function which is in Esri Flex library.

That is a nice piece of work. Is there some manner to configure a single Google basemap into the Flex viewer? Is sounds to me like there is a significant level of customization involved with creating the dropdown lists.

Thanks,
Mike

We are currently using Bing Maps or ERSI online as base maps for our Flexviewer 2.4 app. However, for those regions we are focusing on Google provides most detailed data. We would therefore appreciate to be able to implement Google maps as our base map.

How may we implement this. License should not be an issue. what we need is simple help for the technical solution. How would the code line for using Google as a base map in Flexviewer 2.4 look like and where should a license key be located?

Any assistance is highly appreciated. I have seen the flex sample by izambakci. May you provide the explanation how this was implemented. We don't need sharing the entire project, just the implementation of Google base map.

Thanks,

Thanks Ismail,

for your fast reply and assistance. We are in urgent need of implementing Google as base map for our data in Flexviewer 2.4 and would really regret to quit flexviewer in order to have Google as a base map. There must be a solution, but how...

I wonder if the ESRI flexviewer team has any intention of including Google Maps as one of the options for Flexviewer base maps.

Thanks,

Hi Ivan...

I would like to incorportate Google maps as well in my Flexviewer... Were you able to get it working? If so, would please share your knowledge and code..

Hi Nasif,

I did not yet get closer to get Google basemap for Flexviwer 2.4 to work. Got some fxp and fxpl code from Ismail Zambacki but I am not familiar with that format. I think we need some support from the ESRI flexviewer team on this issue. Hope we may manage with joint efforts.Great to know that others have the same requirement.

Stay in touch,

Ivan & Nasif,

You guys will not be receiving support from esri on this as stated in the first couple of posts there are legal constraints applied by Google that will not allow you to use their data outside of their APIs and products. So even if you are able to get this to work you as putting your organization at risk for lawsuits.

Just to both contradict and confirm Robert's answer 🙂

As a Flex Developer, it should be possible to either (a) extend the tile layer together with the Google Static Maps API - this is the option mentioned in Rex' blog post (see Derek's entry on this thread). Optionally, and with less limitations, (b) is to (similarly) extend the TiledMapServiceLayer and wrap it with the Google Maps API for Flash. Both of these solutions should be doable and OK.

Re: Flex Viewer and Google Maps

RobertScheitlin__GISP — Sat, 17 Sep 2011 01:42:08 GMT

Bjorn,

Thanks for clarifying. The issue with your option b (less limitations) is that the Google Map API for Flash is being depreciated. And the Issue with option a is that the map size would be limited to 640 x 640. Many of the people on the forum that are asking for this ability to use Google Maps as a basemap are not developer and would not know how to extend a DynamicMapServiceLayer or a TiledMapServiceLayer. So maybe every one will understand that though it is doable by a developer there limitations in capability as well as legality to deal with.

Re: Flex Viewer and Google Maps

IvanBaehr — Mon, 19 Sep 2011 09:07:45 GMT

Thanks Robert,

for referring to the legality issue. This is a crucial issue. We have a project partnership with Google Map Maker. The legal issue may find a solution through this partnership. We may look into Bjørn's suggestions although I am not a developer.

Thanks to both for your input.

Hi everybody,

Actually, I have two questions to ask :
[INDENT]1. Is Google Maps API for Flash usable despite the fact that it has been deprecated ?
2. Could anyone please specify the conditions in details for Google Maps use in The Flex context ? and is there legal constraints that prohibit using Google Maps on Flex ?
[/INDENT]

Regards.
