If you have a net savey audience that will enjoy viewing a
3d model of the earth complete with terrain, 3d buildings
and draped with aerial imagery the
Google Earth is the ultimate. The basic version of
the program is free to download and once your viewers have
it installed they can download a file from your website i.e.
(Narragansett Bay Marine
Layers) that will put place markers in their map layers
that will link to interactive content such as panoramas,
high resolution overlays or 3d buildings modeled in
Sketchup. We can even set up the file so that as
more content is added their layers will update without any
additional downloads.
