Update: I added some app evaluation links below, including Trimble and Backcountry Navigator Pro. Galaxy Note phone is working super well. It feels like marriage, when you know you’ve found “the one.” I took the battery out today to test for swapping in the field, easy but would need to be done in a dry environment as doing so exposes the micro SD and SIM cards. An external battery pack might be a better option, but so kludgy with a cord…the games continue.
I may be involved in a web publishing project that focuses on mapping. So I ramped up my GPS experiments. Focus is now on smartphones, which ones work for “real” backcountry GPS use?
1. Battery Life
2. Screen visibility
3. Use in cold temperatures, possibly with gloves.
4. Works in Europe, with good European maps.
5. Moisture resistance.
6. Overall durability (and available waterproof cases).
Larger screens are better. Battery life is a huge issue. Those two concerns led me through a Motorola Razr HD Max (amazing battery, poor screen viz in bright light) to a Samsung Galaxy Note 2. Now we’re talking. Slightly better screen visibility in bright outdoor ambient light, and the huge LCD (5.5 inch diagonal) is the kind of form factor I’ve long felt was much more appropriate for real-world map use than anything smaller — especially the fingernail sized screens on nearly all hand-held GPS units.
More, Galaxy has a stylus that allows super precise and quick waypoint creation, instead of the blunt finger “move the waypoint” game you’ll play with a smaller screen and fingertip. More, the stylus might be key to precision while wearing gloves.
I just finished my first test of the Galaxy battery life. Definitely good, though I wish they’d added 10 more grams of lithium. Saving grace: Galaxy has battery you can swap in the field, so you can carry a spare or two. The unit has virtually no moisture resistance (evidenced by how easy it is to swap battery), so the waterproof case will make or break this evaluation. (Samsung Galaxy S4 Active is waterproof, as are the Casio G’Zone offerings, so those might be the fallback if Galaxy Note with case is just too huge and heavy).
Comment suggestions on GPS/map apps appreciated. At this time I’m running two applications:
US Topo Maps Pro, clean and simple, but has trouble with finger swipe zooming. Uses raster USGS maps that are slow to load but in many cases more accurate and have more information than efficient vector maps such as Google terrain view.
Gaia GPS, more features and persistent zoom, but might be overly complex and perhaps use more battery. Uses slow loading USGS raster maps by default, but might have a way to use Google terrain view topo maps (again, vector based and super efficient).
Polaris Navivation, free and has killer GPS control features that allow you to do things like changing the sampling rate of your GPS to save battery. But for the life of me I couldn’t figure out how to get it to use topo maps, nor pre-load cache map sets for use without data connection. I emailed their tech support, they said none of their map layers have topo lines, but they may add in a software update (a common rejoinder I’m hearing when I catch various app companies blatantly lacking what should be a basic feature in any nav app). In a word, probably a more “urban” geek app than backcountry oriented.
Backcountry Navigator Pro, recommended by readers here, I’m impressed so far but wondering how well it works for creating routes on the fly. I want something that allows me to draw a track/route with my Galaxy Note stylus instead of tediously making 30 waypoints, then connecting them.
Trimble Outdoors Elite, these guys are part of a big publicly traded GPS company, that can have advantages — or result in corporate inertia. Integration with their website is cool; you can publish routes (they make money off that with associated advertising) or you can keep your routes private. I’m looking forward to a full evaluation of Trimble as it could be the one.
Overall, it is clear that smartphones are beginning to hammer the coffin nails of archaic stand-alone GPS units, same as they’ve decimated the point-and-shoot camera market. More later folks about the phones and the apps, after we wring this thing out.
