Satellite Map

Yes of course this can be done, but you must alter the JS file directly for the 5x-1x abnd 6x-1x branches in order to add this behaviour.

Note: Altered files will be overwritten when geomap module updates are also done, so always create a patch of a backup of altered files.

Edit the file jquery.googlemaps.js
Anyhwere inside the function $.fn.googleMap add the map type by calling
map.addMapType(G_SATELLITE_MAP)

For a list of other possible types see:
