GPS Discussion / Help Us Improve Digital Map and Data Offerings
« on: March 13, 2014, 11:45:09 am »
The Routes & Mapping staff of Adventure Cycling have started a program to improve its offering of digital data and maps that will help with navigation using GPS and mobile devices using:
  • Higher resolution tracks that follow roads & trails. They will offer a clear representation of the routes to follow with little or no processing after downloading it from our library.
  • Digital copies of our popular paper maps that are tagged with their geographic location. On compatible GPS & mobile devices, you can see your location on the maps.
Would you like to help us test these new digital products along the Northern Tier Route? Learn more about the program & apply at Geopoints Bulletin announcement.

I think you are making the best of what you have.

Here are some options to consider:
  • Have the unit correct itself with Automatic Routing turned on. As you ride, take those roads that have bicycle signs on them. The unit will recalculate the route to make sure you are still going in the general direction of your destination. This will not be most optimal route, but will improve on earlier selection.
  • Supplement the first option with another map on smart phone or paper map. Use this other map to get a general idea of the best routes back home. Take these routes as you ride. The unit will recalculate to give you detailed routing & turn prompts, while making sure you ultimately reach your destination.
  • Change the map set. Download OpenFietsMap map sets for example. These are free. You can just experiment with them. I understand that Garmin is using them, or some version of them, on their Edge Touring unit.

Are you trying to create routes while on a trip or in advance?

What are you using to create the routes? Is that on the GPS unit itself or BaseCamp?

Take a look at Revelate Designs for various frame, seat, & handlebar bag options.

Once you have downloaded the OSM, how long is the compile process (for garmin device) and is it fully automatic?
No compilation process. You download OSM in IMG file. You copy it to the unit. It just works. Magic! Review my earlier post and another from BikingBrian for download instructions.

You are making a good choice with the Edge Touring. Once you have it, play with it and come back to this forum to share your experience with this new unit.

I like to record all aspects of my trips including performance, temperatures, split times, etc.

I have the Edge 510—see my earlier comments about this powerful little thing. I use it with just about all my activities: hike, run, bicycle, paddle, & walk in the park.

To confirm, once I have the Garmin device (hopefully edge touring) and copied the maps over
The Garmin Edge Touring device already come with "preloaded Garmin Cycle Map". These are based on Open Source Map.

It may only have maps of your regions, if you are outside the US. In that case, you will need to add the US maps.

(providing I can pick up signal)?
I cannot think of any place in the United States where you cannot pick up the signal, rain or shine, unless you are in a cave. It will take a few minutes when you first turn on the device to locate the satellites.

There are no subscriptions or any other associated costs?
Correct, GPS signal is courtesy of paid taxes ;)

All the areas I looked at in Northeast USA seems to be well mapped. Check the map for the areas you are interested in directly at

I recommend minimum 4GB SD memory card, preferably 8GB. The file size I used last was close to 3.5GB. I would leave extra for additional files to store on the card.

Yes to all of the above. In fact, Garmin is now shipping Edge Touring model with OSM.

Take a look at earlier discussion for instructions and test results.

The recommendation above from SlowAndSlower should work with a text editor. That would be the way I do it as well.

Another option is to use Garmin's BaseCamp software:
  • Open the GPX file in BaseCamp
  • You will notice the file contains waypoints and routes. The routes are usually at the bottom of the list
  • Select each route and "Create Track from Route"
  • Once you have the tracks, select all of them and select to "Join Tracks"
  • Export or save the final track
This option gives you the opportunity to edit the route in the software while you are at it.

Note that "Tracks" are different from "Routes" in GPX language, especially with Garmin, as there are limits to each. In general Tracks work more universally and reliably. Routes are more suitable for devices with maps to give navigation prompts.

You can convert between both as you need.

Any clues on how to resolve this?
What is it you are trying to do?

For each ACA Route, there are multiple GPX files, each file contains multiple sections.

Have you found an alternative to Google Latitude
  • With Find my Friends, the iPhone locator is always on. I exchange location with a few close family & friends. They know my location at any time.
  • While on a ride, I always use Garmin Live Track with the Edge 510:
    • The data is updated constantly showing accurate location at all times. I find other apps to lag behind in showing the location and tend to be slow in retrieving the information.
    • Live Track shows the route taken along with other information about the ride such as speed, distance, and elevation.
    • Minimum impact on battery. In a test I did a few weeks ago, while temperature was hovering around freezing, after three hours of riding, with normal use of phone for a few text messages, phone call, etc, including Live Track, the iPhone 5s was still at 55%. Other apps drain the battery much quicker as they use the phone GPS. During that test, as soon as I turned the phone GPS on, the battery drained fully in about 40 minutes.
  • Life360. I have not used it but read recommendations about it.
The app store shows many options when searched for "share location".

Please share other options that you find.

GPS Discussion / Re: ACA GPS files on Google Earth problem
« on: December 03, 2013, 09:32:24 pm »
Here is a sample file of GPX track of Section 1. Import that into Google Earth. It should work. Remember that the distance is still not the same.

I followed these steps to create this file:
  • Edited the original GPX file from ACA to remove all Waypoints. Only the Routes remained. This is because Waypoints are irrelevant to the Route.
  • Edited the file from Step 1 above to merge all the Routes into one route. This is to make sure that the track is rendered in the correct order.
  • Converted the file in Step 2 above from Route to Track using GPSies web site

Do you have any idea why when I enter ACA data into Google Earth, it displays all the waypoints, but for some sections it displays only about 1/3 of the route (for example, WE 1 and 4) while for others it displays the entire route (WE 2 and 3)?
Not really. I can only take a guess.

The original GPX file from ACA was created with a very different purpose in mind using Garmin software to use on (mostly Garmin) GPS devices. It has much more data than a basic KML file would contain. It seems that Google Earth struggled in converting the GPX file into the KML format it needs.

Tracks, meanwhile, are a simpler format that maps more closely to KML. That seems to have done the trick.

I'm trying to get maps with elevation profiles of some ACA routes.
Your best bet is to use the paper maps published by ACA. They include an elevation profile.

First I tried using the ACA GPS files.
This is one  way to get a general idea about the elevation profile. Once you have the GPX file, load it onto your favorite web site tool such as Ride with GPS or GPSies. Both sites will show you the elevation profile and total elevation gain.

The accuracy of elevation data generated on web sites is frequently disputed and vary greatly by web site. I have seen it vary by 50% when calculating the elevation gain. Nevertheless, the profile can give you a general idea about the route.

With Section 2, it seemed to map the whole route and give an elevation profile, but the distance it shows is only 300 miles, much less than the ACA says it is.
This is expected. The GPX file posted on the ACA web site (at the time of this post) is a general representation of the route. It has a series of route points that could be > 10km apart, connected by a straight line, instead of exactly following the route. Therefore, the straight line is expected to be shorter than the meandering actual road.
