GPS units for recording rides?
Greetings,
Not even sure if this can be done with a GPS, but I'm going to ask anyway..... Most of the areas we've been biking recently aren't mapped in any way, shape or form. Consequently, it's a bit of a lottery when we decide to try a new area, re the length/condition of the trails etc. I figure if that's the way it has to be, then at least we could map the areas ourselves as we ride them. So, what I'd like to know is: - Does anyone use a GPS to map their trails (can a GPS even be used to do this)? - If so, is there one that is particularly 'good' for what I want to use it for? Ideally, I'd like to be able to dock the unit with my PC and download the data to turn it into a map of waypoints etc afterwards. I can get aerial photomaps of most of the areas around here that we've been so far. They're to scale, so I'd be able to mark out our route on these for future reference......for us and anyone else who wants to ride the area. Thanks for any advice that might be forthcoming :-) MrBonk www.mrbonk.com |

Pretty much all GPS receivers allow you to save your tracks and waypoints. I use DeLorme's Topo USA 5.0 to create my own maps. You will need to make several runs over trails to get the most accurate readings because of the inherent error in any GPS receiver. The weather, trees, mountains, buildings, etc. will affect the GPS's reception. Even the time of day will cause reception errors because the satellites' positions are constantly changing. Topo 5.0 also has a feature that enables you to buy aerial and satellite images from the company, which you can then place on top of the maps. -- Ryan |

If you've got the $$$, the best I've seen is the Garmin ETrex Vista.
The Legend is a cheaper option. Pretty much all decent GPS units will record waypoints as you ride, and allow you to download them to your PC, and plot the route over a topo map or sattelite photo. With the Garmin units, if you want to download detailed topo info to the GPS, you need the Garmin software... but once the data is on your PC, there are lots of mapping options. The results with National Geographic topo USA are pretty cool -- not only do you get a trail on a topo map, but you can also plot your elevation profile and get a summary of total feet climbed, etc. Wissenbach Map3D is also pretty cool, and free. The Vista has a barometric altimeter, which is more precies than GPS, for instantaneous readings on the trail. Once you plot your course on a topo map, the Nat Geo software seems to give accurate readings as well. The Garmin units seem to better for trail use, as compared to some which are more suited for cars and city navigation. For those who haven't seen it, check out www.terraserver-usa.com It's cool how you can switch back and forth between topo and sat photo maps for the same location/scale. Justen |

GPS units for recording rides?
good info in the thread already ... but i'll throw a link to gpsbabel:
http://gpsbabel.sourceforge.net/ very handy because it lets you translate between many formats, including proprietary ones. i actually hope tools like this will drive vendors into supporting open standards (like gpx?). i use gpsbabel to download from my eTrex, and then use a stupid/simple program i wrote to find the total gain for a ride. someday i might improve it to do time-to-distance and time-to-elevation charts. i've also got national geographic topo ... but just use that for printing maps (including routes i've downloaded from trail guide sites). |

Gee, you mean that someone with orienteering skills might be able to do better with a paper topographical map? Whoda thunk? JD |

- Does anyone use a GPS to map their trails (can a GPS even be used to do
this)? Trees are going to be the biggest problem. A GPS unit will track a certain number of satellites. When you get close to trees the signal gets deflected or obscured and will cause you problems. a combination of aerial photos and GPS is better. You can get aerial photos at terrafly.com - If so, is there one that is particularly 'good' for what I want to use it for? I use ESRI ArcPad for mapping. You can download the demo version at www.esri.com, which will run for 20 minutes before timing out. If you search around the Internet you can find a crack for the software which will allow you to run it in full registered mode. ArcPad works with several different GPS units. I use a cheapo Delorme Earthmate, but ArcPad supports most protocols. The upside of using something like ArcPad is that the files you create are standard shapefiles, or AutoCAD dxf files, and are easy to work with in just about any software. |

After the first couple of responses, I went looking on the Garmin site and
actually thought the 201 looked pretty good, so I might get myself one of those. I really don't need anything more than that, even for the other uses I had in mind (kitesurfing etc). Altitude would be nice, but certainly not essential. Will the 201 record my max speed, average speed etc? Some of the GPS units I've seen mentioned in other forums do this.
