General Discussion / How do you like the new forum?

How do you like the new forum?

I like it! Fast and does not stall. John Sieber, was it you who chose and installed the SMF software? Good going. I expect it saves you a deal of grief.

Members: this forum has many more options and features than we are used to. If it seems bewildering, give yourself a couple of days to get familiar with navigating it.

GPS Discussion / Do you/would you use a basic or a mapping GPSR?
« on: June 15, 2008, 10:15:36 am »
The good folks at Adventure Cycling are considering an update of the GPS database. They revise its content frequently, but its structure and type of data have not changed in its six years of life.

An important choice is whether to support basic non-mapping receivers or mapping receivers that guide you along roads and include listings of lodging, museums, and other points of interest (POI).

The present database is built for non-mapping receivers that navigate in straight lines from one waypoint to the next. They can tell you that your campground is 4.2 miles northwest.

Mapping receivers work very well with the present database and they add more information like turn-by-turn directions including road names to the campground. They might also add that Randy's Quik-Stop is one mile before you reach the campground. Their POI listings contain many--but not all--of the POIs noted in the ACA maps and GPS database.

The difference in price is substantial. $100 will get you a new basic receiver and a handlebar mount. Used receivers are plentiful as people move up to mapping units. Mapping receivers with enough memory for a trans-continental route cost $300 - $550 with a handlebar mount. A set of U.S. maps adds about $100.

The question, then, is whether to continue support for basic GPSRs by including all the POIs in the Adventure Cycling maps in the GPS database as well, or whether to include only the campgrounds, which are not well covered by the mapping GPSRs? If few or none of us use basic receivers, the time would be better spent on other routes and mapping chores.

Please help by replying here.

1. Do you use a GPS receiver on your bike?

2. If so, is it a basic unit or a mapping unit?

3. Do you plan to buy a new (or a different) GPS receiver for cycling?

4. If so, would it most likely be a basic unit or a mapping unit?

Thank you,

Hi Paul, I see you are checking in from the Northern Tier ride. Somewhere in North Dakota by now? I'm enjoying your blog (fond memories) and would like to hear how the GPS is working--or not working--either here or in the blog.



GPS Discussion / Tracks in Wet Forest: Two GPSRs and Three Antenna
« on: August 04, 2004, 02:55:56 pm »
If you ride in the back country or hike with a GPS receiver, this may be of interest.

I made some test tracks in really wet woods to gather evidence under controlled conditions on the perennial topic of tracks under tree cover. The results are not surprising. The executive summary:

1) Typical consumer GPS receivers can record useful tracks under heavy, wet foliage when reception is not obstructed by the user.

2) Forget about carrying the antenna on your body in the forest. Hand-hold it or use an amplified antenna on your hat. (13KB) includes three files. TrailTrack.mps and TrailTrack.gpx contain the tracks in Garmin and GPX formats. TrailTrack.txt is a more detailed report.


GPS Discussion / GPS routes available

GPS routes and waypoints are up on the Routes and Maps page of the web site for three routes:
  Great Divide
  Lewis & Clark

If you have Garmin MapSource or another GPS mapping program, these are a great way to improve a winter evening.


GPS Discussion / Putting waypoints into Street Atlas

How to get waypoints into Street Atlas? The question came up in another venue, but I thought I would bring it here as well.

The free program G7ToWin converts our OziExplorer format files to Street Atlas files. Set it up as described in the GPS Data User Guide, available at

G7ToWin's URL has changed recently. It is now

Hi all,

A database developer and volunteer Adventure Cycling member who rides many miles with GPS, I designed the GPS data files, populated them, and wrote the first drafts of how to use them. I would like to hear your comments, questions, and especially suggestions for improving the GPS database.

The web site and how it delivers the files is not my territory, however. Please contact webmaster Paul Adkins at about it.

Happy cycling,

Fred Hiltz

Litespeed, I removed two of the triplicate messages here as you requested. The third one disappeared along with the second; maybe an operator error but more likely this flaky forum software. Please re-post it if you wish. I am sorry to cause the inconvenience.
