So I fired up the phone and courtesy of a Vodafone Femto Cell which gives 3G coverage in the middle of nowhere, we used Google Maps to virtually walk down Bath Street and stand outside the restaurant, noting its name and phone number. Job done. <a title="Pea soup with a wild camp. Ben Avon and Beinn a’Bhuird" href="http://stravaiger.com/blog/2008/09/21/pea-soup-with-a-wild-camp-ben-avon-and-beinn-a039bhuird">Rewind</a> a couple of years to where I met a bloke near the summit of Beinn a&rsquo;Bhuird who had a phone he kept looking at and I&rsquo;m sure he had earphones dangling too. So I suspect he was using an early form of GPS, probably a Nokia as they were popular back then but strangely he had joined me on the edge of the cliffs. I was there to take a bearing where the cliff edge turned south, so I knew exactly where I was for an accurate bearing to the summit on the featureless plateau but he had a GPS and only now I&rsquo;m wondering why on earth he ended up at the same spot as me. Why didn&rsquo;t he navigate straight to the summit? Leaving aside such questions, I think I was witnessing the birth of smartphone based navigation. A topic much in the news these days and tipped to knock GPS units into the void. But just how accurate and reliable are GPS&rsquo;s?</p> http://stravaiger.com/blog/2008/06/14/the-electronic-hills/ Sat, 14 Jun 2008 00:00:00 +0000 http://stravaiger.com/blog/2008/06/14/the-electronic-hills/ <p>Sometimes I wonder if I&rsquo;ve lost the plot. I used to just grab a map, yellowing and weather beaten, from the shelf and head up the hill. As long as I had the compass and a couple of rolls, that was me for the day. Now it&rsquo;s computers computers computers!</p> <p>I should be out on the hill today but I&rsquo;ve just finished marking my students&rsquo; TMA submissions, on the computer and moved on to the next task, coming up with a quiz for one of the evening entertainments when I&rsquo;ll be leading for the HF, on the computer. Google and Google Earth instead of Cuillin and real earth beneath my boots. Not to mention loading up the GPS with route info for the trip.</p>
