Clean Cruising has successfully geocoded and mapped the world's cruise paths & ports to be viewed in earth & maps. Individual itineraries are created "on the fly" to display the ocean or river path down to the port mooring. Our current project is to incorporate 3-D models of the world's cruise ships into these paths to provide time-line viewing of virtual cruises by either ship or region.
