Last week, over the lunch time, I was chatting with some of my colleagues regarding Dynamics AX and Map Integration, Till then, I was not aware of the fact that in Dynamics AX 2009 Address form we already have a "Map" button which invokes the Bing maps as shown here
But, Bing was not able to provide us the proper location for some addresses which Google Maps could provide - Food for thought for the Bing devs/SDE's.
I was curious to see the Code Behind the "Map" button, which led me to the SmmUtility Class > mapIt method.
Then, next step was to find out how to invoke Google Maps by passing query string in the url, My best friend Google never lets me down :-) and I hit upon this wonderful site which shows how to pass different query string parameters in the url http://www.querystring.org/google-maps/google-maps-query-string-parameters
From there on it was pretty straightforward, following code snippet helped me to show up the google maps
Thatz it! Pretty easy, rite? :-).
