eleavtion data

Hi there,

Im trying to get an elevation profile to my track/route, however apparently my base camp does not have any elevation data. My question is, how to get elevation data into base camp so that base camp can plot elevation graphs. Can anyone tell me how I can do this?

Thanks a bunch.

PS: I'm using garmin edge 810 with city navigator Europe NT.

Probably you'll have to buy the appropriate Garmin topographic maps. City Navigator certainly doesn't have altitude information. I don't think there's any way of acquiring just altitude data.

Thank you Schinder for your reply. Unfortunately my life savings are already spend on the edge. Is there not a way to use free altitude data? Google earth has it, and on garmin connect also altitude data is available (unfortunately this doesn't work for longer rides).

I do not know of any free programs that will just add elevation to your trackpoints.

I do have 3 that I paid for that work very well. I have tested the results between them and the overall gain numbers are within 2-3%.

TopoFusion.

Fit File Repair Tool.

Natl Geographic 24K State Series. (the most difficult to use)

Garmin doesn't really do free, and they can be unreasonably restrictive with their maps. But openstreetmap.org does free. I just took a look at the maps for my local area (central Pennsylvania) on their web site and, given the topographic rendering I'm being shown, it looks like they include altitude data. You should check them for the area you're interested in and download the maps and try them on your Edge and in BaseCamp. The only openstreetmap.org maps I have installed locally, the special Fenix versions from http://www.gmaptool.eu/en/content/maps-garmin-fenix, don't seem to include altitude info that BaseCamp can use like it does with my Garmin topo maps, but maybe the European maps do. There are instructions at http://wiki.openstreetmap.org/wiki/Topographic_maps_for_garmin_devices

Only the maps from Garmin that contain DEM data can be used in BaseCamp to add elevation data to a track. The Openstreetmap based maps don't contain DEM data, because nobody (except the people from Garmin) knows how to put DEM into a map...

I do not know of any free programs that will just add elevation to your trackpoints.

JaVaWa RTWtool can add elevation to track points, and it's free.

That is the a really handy tool! However, it does not allow to add elevation data to routes, only to tracks. This would be fine if the edge was willing to navigate tracks, which it is not if the course is longer than +/-100k. Is it even possible to add elevation data to routes, and, if so, how?

To sum up where I am: I now have a track with elevation data and I want to convert it into a route with elevation data. Converting the track with elevation data into a route using basecamp returns a route without elevation data.

Am I correct in understanding that these are elevation data sets projected on an existing map? Are these based on DEM or contours?

TopoFusion has many options including straight DEM and it gives a preview of what the gain will be for each possibility.

Fit File Repair Tool uses DEM from Map Quest. Mathias can correct me if I am wrong.

Natl Geographic does not say how they do it but it will match their 24K topo when finished.

As JaVaWa said above, the ONLY way to get DEM on Garmin is to purchase one of their topo maps. The software used to insert DEM into a garmin map is not available for third party mapmakers. The Garmin 24k maps have high resolution DEM that looks pretty good to me (I would say it is based on the USGS 1/3 arc second NED). I know they're expensive, but if elevation data is important to you then it might be worth it.

Strictly speaking it is possible to add elevation data to via points in routes, but since the software and the devices of Garmin don't do anything with it, it didn't make sense to add that option to RTWtool...

The edge shows an elevation map while riding. This would give me, while riding, a clue how much of the climb is left. However, I need elevation data in the pre-programmed course/track/route. (I believe it is <ele>...</ele> within <trkpt> for tracks, in routes I guess they should be located in <rtept>)

It's not the length of the track that is the limiting factor for the Edge, but the number of track points; I believe the max. is 10,000 (I'm not completely sure about that number).

I do not have a problem with the number of track points, but the edge has a bug where it gives a route calculation error when feeding a long track. For some reason it calculates the to-be-followed-route when feeding it a route without problems. I don't know why, emails to Garmin tell me to turn it off and on again, when reporting that this didn't work all remains quite at the Garmin front.

You can reduce the number of track points with RTWtool; it is also possible to convert a track to a course.

True, but converting from track to route removes the elevation data.

I don't understand why it is not possible to map free DEM data on a navigation map. Especially since a lot of DEM data is free, one might think of ASTER.
