Know everything about your track
Each Track has its own page, you may access them with several urls (in these examples, 123 is the number of the track) :
- the short url : http://tracedetrail.fr/trace/123 ou http://tracedetrail.com/trace/123
- the url which specifies the language (you can replace "fr" by "en") : http://tracedetrail.fr/fr/trace/trace/123 ou http://tracedetrail.com/fr/trace/trace/123
This page is divided in to two parts, a block recapitulating all the information on your track and the map in 2D, which you will have to post by means of the button situated bottom right on small screens :
The functions on the map
Because, to us it seems important to be able to see the track on you map and your profile at the same time, Trace de Trail offers you a profile superimposed on the map, but you can choose whether to see them together or not.
Otherwise, the profile and the map are dynamically linked : you move on the map? Your position is shown on the profile ! You move on the profile ? Your position is shown on the map !
You can also show the list of layers (button top left of the map) to choose a suitable map base, but also to modify the symbols of your track (colour and thickness). This list is usable even when you look at the map in “full screen” mode.
Know that... two functions which maybe you don't know :
- Use your keyboard's Shift key to limit the scope of your zoom !
- Use the keys Alt + Shift to pivot your map !
The essentials at a glance
Next to the customisable image of your track, you will find your track's main data :
- The distance, which takes in to account the ascent/descent
- The maximum and minimum altitudes
- The longest ascent and descent, understanding that an ascent of less than 1000m is interrupted by a descent representing 10% of the ascent in progress with a minimum of 10m; beyond 1000m, a descent of 100m interrupts the ascent. The principle is the same for the calculation of the longest descent.
For a same track, the data can vary according to the calculation method and parameters used for calculating the profile.
The features of your track
You will find the following features :
- The location of the start : town and region or country.
- The location of the finish in relation to the start : if they are positioned less than 1000m apart, the track is considered to be a circuit.
- The majority of the terrain encountered : road, path (more than 1m wide) or footpath. Be careful, a track using only roads will not be posted publicly on Trace de Trail, except in the particular case of urban trail-races.
- The access code if the track is private (optional)
- The number of points of making up the track, as well as the average distance between two points which acts as a quality indicator for the track (a smiley is there to help you to interpret this value !)
- Origin of the altitudes : altitudes of a track can be taken by a digital elevation model (DEM) or measured by a GPS
- Ascent/descent threshold : the minimal difference of ascent/descent between two points so that this is accounted for in measuring ascent/descent. An increase of this value tends to decrease the ascent/descent calculated.
- Distance threshold: the value used for retesting the points on a track. If two points are placed at a distance greater than the threshold, intermediary points are added to calculate the ascent/descent. An increase in this value tends to diminish the ascent/descent and the distance calculated.
- Smoothing : if, over three points, there is an inversion of the direction of the variation in altitude, the difference in altitude taken in to account is divided by two.
This part is includes a descriptive text that you must complete upon the creation or modification of tracks, and the table of passage.
By default the table of passage includes only the start and finish points. You can add intermediary points by activating the option “ Post in the table of passage” when you add points of interest to your track.
Discover who added this track, as well as the last tracks that they have added. You may contact another Trace de Trail user by going to their page, then by using the button “Send an email” or by adding a remark on one of their tracks.
You can not only download gpx or kml files of your track for transferring to your GPS, the profile in the form of an image, but also recuperate the code necessary for inserting the cartographic window of your track on to you own website..
On each track you have the possibility of adding realisations for sharing your times and informing other trail-runners about the conditions you encountered.
You wish to contact the owner of a track very quickly? Leave a remark, they will be alerted by email as you will be if they answer you (if you have not deactivated this option on your profile !)
Know that... On certain tracks you can find other optional information blocks which allow you :
- to see the photos of a route as a slide show
- to discover certain alternatives to the route
- to obtain itinerary details with main changes of direction
- to add a remark which will be sent to the manager of a permanent route. The latter will inform you when your remark has been taken into account !
