ArcGIS API for Google Maps

From Google Maps Mania Blog:

The ArcGIS JavaScript Extension for Google Maps allows map developers to extend the Google Maps API to use ArcGIS Server services. With the extension, you can add your own data to a Google Map and embed this map in your own page.

ESRI have a number of examples of what can be achieved using their new API. Examples and reference for the API can be found here. Using the API you can:

  • Display your own maps on top of a Google Maps base map.
  • Execute a GIS model and display the results in Google Maps.
  • Search for features in your GIS data and display the results on Google Maps.
  • Find addresses using your own address locator and display the result on Google Maps.
  • Display attributes from your GIS data on the map using the Google Chart API.
  • Allows others to add GIS functionality from your server as a Google Mapplet.

On the surface, it seems like this news would only be of interest to GIS professionals and geeks like me. But the truth as I see it is that this development for extending the popular ArcGIS platform to the internet will lead to a whole host of new online applications and mashups that will be both fun and useful.
