downhill ski guiding) to full whiteout navigation (traverses across icefields). The end result is a route plan that will be much more useful than one created with an NTS map for anything from onsight navigation in complicated terrain (e.g. Google Earth (GE) is extremely accurate and allows for precise route planning that, like Ozi Explorer, is as easy as point and click but with the benefits of 3D View and many organisational tools.

This article doesn’t have a lot of detail, but despite being dated it gives a valuable overview that should help you link the high-tech features of Google Earth and Smartphones with the old(er)-school robust reliability and performance of a Garmin GPS unit. This summer’s Disaster in the Alps, is a perfect case study: 10 skiers, led by a mountain guide, got lost in a whiteout as a result of relying on a Smartphone that failed to perform. However, just as GPS units did not render a paper map and compass obsolete, neither do Smartphones, despite their convenience, render GPS units obsolete. A lot has changed over the years with respect to digital mapping technology, most notably the usability of smartphones as navigational tools. This document was used as a handout for several Continuing Professional Development sessions I conducted for the ACMG, 2012-15.
