I make maps and think about these resolution issues a lot. Not unusual for roads to be off by 300 feet on Garmin’s 100k topo’s. In fact, it wouldn’t be unusual to be off by more than 100 feet.

Yes, it would not be at all unusual to be off by more than 30 feet. 🙂 If you’re using a map application on your computer, and it has inaccurate data, then that’s what you will transfer to the GPS. Well there’s no way around “garbage in, garbage out”. This data provides shaded terrain and 3d views in real Garmin maps, and can add elevation data to tracks. There are some things which we haven’t figured out, such as how Garmin uses DEM (digital elevation model)data.

The free maps are made with third party tools that have reverse-engineered the Garmin format. They will not provide any support for third party maps, but will help if you have problems with their own products. You also need to understand that Garmin considers their map format proprietary and has never disclosed it. Of course, my own maps are better than Garmin’s 😉

Since they’re free, the best way to compare is to just download the ones that interest you and decide for yourself. The free maps are created by many different people who have varying levels of experience, different goals and using different datasets. I am one of the authors of the free maps at GPSFiledepot, and it’s pointless to attempt to compare them with Garmin’s products.

The older National Parks series maps have very limited coverage. Don’t confuse with US TOPO 24K National Parks In my testing, the POIs (and number of POIs) in this product were comparable to those found in Garmin’s City Navigator product. And it’s very nice to be able to use them on your new toy tool.

Now I know most readers probably don’t own an entire stable of GPS receivers, but many of you do upgrade from time to time. The DVD and micro-SD TOPO US 24K products are not locked to a single device, allowing you to move maps with routable roads from one Garmin handheld to another ( downloads are locked to a single device). And since many trails are missing, this feature isn’t nearly as useful as it could be. gpx tracks onto a newer Garmin handheld, the advanced track navigation feature offers many of the advantages of routable trails. The one thing trailwise that TOPO US 24K has going for it is that the trails are routable. gpx file from a trusted source, but another good option is Jim Bensman’s free MyTrails map (or NW Trails if you live in the Pacific Northwest). Those screenshots above? The Appalachian Trail runs that ridge, but it’s missing from both Garmin mapsets! The surest way to get good trail coverage is to download a. But truth be known, both products are really bad. Indeed, you can see it in the images above. Many people have reported that there is less trail coverage in Garmin’s 24K maps than their 100K products, and I have found this to be the case in spot checks of various areas. Still, with plenty of free topos at GPS File Depot, this just doesn’t rank as a reason to buy Garmin’s product. In this case, common in the eastern US, the 24K map shows 40’ contour intervals vs. In the images below, a 100K scale Garmin map is shown at top, with TOPO US 24K below it. The TOPO US 24K maps give you greater detail, with more closely spaced contours. Sure, you won’t hear audible directions, but you don’t have to transfer waypoints to a second device (like a nuvi) just to navigate to the trailhead. This means that if you have a waypoint for a trailhead, you can mount the GPS receiver on your dash and get turn-by-turn directions on compatible Garmin handhelds (as shown at right). The other is that these roads are routable. TOPO US 24K maps use the more accurate NAVTEQ road data however, just like Garmin nuvis. People look at their unit and think it’s a GPS accuracy issue, but it’s just that the road is misplaced on the map. Garmin’s 1:100,000 scale topo products utilize TIGER data for roads, which are almost invariably off from the road’s true location. Strangely enough for a topo product, this is one of the best reasons to buy TOPO US 24K. Let’s go over the different features, one by one: Accurate and routable roads
