GPS on Android - Backcountry Navigator

Permalink I've never owned a GPS device. Heck, I've never even really used one, other than a couple times in various peoples' vehicles. But when I recently became the owner of a Samsung Galaxy S Captivate (from original iPhone), I couldn't help but wonder how I could use the GPS built into my phone for purposes other than finding my wife the nearest Starbucks.
With little fanfare, I installed the demo version of Backcountry Navigator. A quick rundown of the features told me it would do offline map caching, for use off of the data network (basically, all the time I would actually want it), allow me to mark waypoints, record tracks, and even download USGS aerials. Better yet, the demo version was completely free, and was full featured - allowing full use of the application for the demo period - 16 days. Its quite simply the best demo arrangement I've seen in the Android marketplace (or iOS App Store for that matter). No ads, no features removed, just 16 days to decide if you like it.
As a flyfisherman, I've always wanted to have some of these functions. There are several drainages, for example, which I have fished from different access points, of curiosity of course, is the space that has remained out of range between the two - having a GPS mapping solution takes out the guesswork of 'How close am I to where I fished up to last week?', or 'How far to the next tributary?'
So on to the app itself: The interface is simple, basic, and altogether a bit on the boring side (Read: All about function). I will take the liberty of assuming your use of the app will be similar to mine: Download maps of the general area you plan on hiking/fishing, then use on-stream for navigation. I'll start out with an overview of the basic functional flow.
You'll first take a wide-zoom look at the area you want to capture maps, tap to open the "Select tool" and create a large box (figure larger than you need) to download the maps for this area.
Clicking the download button will allow you to select your map source (mytopo.com is default) and the detail level (15 is more detail, 6 is less - I have absolutely no idea what the numbers represent). Clicking start download will being the process of pulling those maps down from the servers - and that brings me to my first beef with this software (or all software that is pulling from these data sources) - the map servers are slow. This isn't something you want to do on the side of the highway while you put your waders on and prepare for a hike. This is something to do ahead of time, download huge swaths of map tiles for areas you fish, and never worry about download speed at the time you go to use the software.
Once downloaded (or even technically on the data network if you're at home), the maps offer the same level of detail you've come to expect with Topo Maps from various sources (as i am quite certain they all pull the tiles from the same sources).
Tapping the menu key will allow you to select even more options, such as putting the app into "Saved Maps Only" mode, marking waypoints, recording tracks, or entering full screen mode which will hide your notification bar.
As a whole, this app does, at least for a fly fisherman, exactly what I would expect it to do. The maps are stored forever (unless you delete from your phone's memory) and work very quickly and smoothly from local storage.
There are a couple other apps that do similar functions. I'll admit to having not used them much, largely because the Backcountry Navigator had the best demo period, and it did everything I asked of it.
Backpacker Magazine has an app called "Backpacker GPS Trails", though it doesn't offer a free trial that I can tell. There is also an app called "Gaia GPS", which is available for both Android and iOS. The demo version of these apps are both ad supported, and do restrict the amount of map downloads you can make.
Backcountry Navigator does have a few quirks that I would like to see improved, however. The ambiguity of some of the numbers is a bit bizarre, for example, when downloading the maps, it’s not made clear which is a finer detail, 6 or 15 (other map sources have different scales also). Additionally, when downloading the maps, the notification bar indicates a percentage complete of a number, but what that number represents is never mentioned (4% of 6032 downloaded). Numbers should have units of measure - whether that is KB, MB, or Tiles... I would like to know what that large number is that I am downloading. Finally, I would like to see a periodic check-in tracking option, instead of continuous tracking, purely from a battery standpoint, specifically, I would like to tell the app to Turn on GPS ever "XX" Minutes for "X Minutes" and record the track in a series of points or vectors, rather than a battery-draining continuous track.
But other than those minor qualms, I have little reason not to recommend this app to friends and family who have an Android, or who may be considering one.
Search for it in the Market, or use your barcode scanner to grab it on AppBrain.
