Private Expeditions is a company founded by Paul and Jane Deakin, that takes people to some of the largest mountains around the world, such as Kilimanjaro, Everest and Machu Picchu, for private expeditions. They’ve recently added narrated videos that heavily feature Google Earth imagery to help show details of each of their routes. A great example is this route map of Mera Peak in Nepal:
From their press release:
The popular company recently launched 3D videos of all its trekking routes. These high-quality videos use Google Earth technology to show potential hikers the exact trails they will take when traveling with Private Expeditions. With a concise narration, graphic trail designation, and added photos of climbing conditions, the 3D videos give viewers a sense of where they are headed when choosing a particular route.
It’s a great use of Google Earth and an excellent way to help show this kind of information. I would hope that they’d release this data in a format that you can explore on your own, such as a KML, but for now it’s simply embedded in their videos.
