[Geomoose-users] Extension of GM/OpenLayers Google capabilities?

Johan,

   GeoMOOSE also supports OpenLayer's XYZ layer type, but I don't think that 
will help.

   I couldn't find much info on Google Earth Enterprise and the API, other than 
Google's note about "extending the familiar Google Maps API" 
(http://www.google.com/enterprise/earthmaps/deployment_options.html).

I expect accessing your Google Earth Enterprise server (using it's native tiling 
mode, not WMS) would require something like:

- setting up your HTML to load the Enterprise server's API javascript
- enhancing OpenLayers to have a .GoogleEnterprise layer type (sub-class of the 
existing .Google layer type?) to access the appropriate functions in the API
- enhancing GeoMOOSE to use this layer type, including setting the URL of the server

And there's the question of authentication.  Since each of your users has a 
unique username/password, they'd have to be able to enter those at each session. 
  Perhaps Google's "extented" API would handle that; if not, you'd have to do 
that in your JavaScript.

Sounds exciting!

Best Regards,
Brent Fraser

Currently GM only supports WMS, MapServer, Google, ArcGIS Server REST API and Bing layer types.  We have a client that is paying us to add tilecache this month.  If the State is publishing the layers in the standard google tile format then you should be able to use it right out of the box.  I don't know much about the google earth server to know if it publishing tiles in a 2D or 3D tile format.
