google earth exhibit?

[Matt Gilbert]

On the Gogle Earth API site it says "If you have an existing Maps API
site, you can 3D-enable your page with as little as one line of
code." (http://code.google.com/apis/earth/)

Has anyone tried this on a Google Maps Exhibit? Seems possible.

Hi Matt,

Yes, this is rather easy to do, at least just to get your map
Earth-enabled. And it looks pretty cool. I haven't tried anything
sophisticated yet with the GE plugin. One of these days....


There are several ways to do it but I've only tried one. First, add a
mapConstructor function to your map view

ex:mapConstructor="newMapConstructor"

Then, add the javascript function newMapConstructor() somewhere on your
page. Since you are now constructing your own google map from scratch,
you need to add a few lines that Exhibit normally does for you. Here's
something that works well

function newMapConstructor(mapDiv){
map = new GMap2(mapDiv);
map.setCenter(new GLatLng(39.2,-75.4), 8);
map.addControl(new GLargeMapControl());
map.addControl(new GHierarchicalMapTypeControl());
map.addMapType(G_SATELLITE_3D_MAP);
return map;
}

The "G_SATELLITE_3D_MAP" control enables the Google Earth plugin (which
must be installed on the client to work.)

You can also add any of the map controls listed in
http://code.google.com/apis/maps/documentation/reference.html#GControlImpl


Hope this helps.

David,

What do you think about adding the Google Earth plugin button as a map view settings?   Yes, I know it's another setting but I don't think that's necessarily bad.

Seems like a simple edit in Exhibit.MapView.prototype._constructGMap (in map-view.js) is all that's needed (outside of the adding the additional setting spec), adding something like the following at the end of that function.

if (settings.earthPlugin) {
      map.addMapType(G_SATELLITE_3D_MAP);
}

Thanks! That totally worked!

I'm hoping to do some more advanced stuff, generating polygons
(hopefully server-side) in a KML. I wonder if you or anyone else could
help point to a place where I can intercept and manipulate the data
that Exhibit is making. (is it/can it be in KML form?) If you're
curious, what I'm working on is a more dynamic and faceted in-browser
version of this:

Thanks!
