Tools: Tour Segmenter The tour segmenter can split a tour into segments by using different algorithms. Values for distance, time, speed and others are computed for each segement to analyze a tour. The tour segmenter can be opened in the toolbar with  . |  create segments with Douglas-Peucker | 
create segments with ascending/descending altitudeÂ

Create Segments The algorithm, how a tour is segmented can be selected in the Create segments dialogbox. Algorithm
| Description
| by Altitude (with DP)
| creates segments by using Douglas-Peucker (DP) algorithm which finds the min/max values for the altitude. The tolerance (epsilon) can be adjusted with the Tolerance slider. The default value for each tour is 50, a modification is automatically save in the tour. | by Pulse (with DP)
| see above by using the pulse values
| by Distance
| splits the tour into equally sized distance segments, the distance for one segment can be set with the Distance slider | with Markers
| creates segments according to the markers which are created for the tour
| with Ascending/Descending
| this algorithm creates segments by finding ascending/descending areas which have a minimum altitude difference. The minimum altitude difference can be set in the listbox. This algorithm is used to compute the elevation gain for a tour and is available as a segmenter algorithm to visualize how the elevation gain is computed. You can set the default value for computing the elevation gain for all imported or modified tours in this preference page. |
Actions 
| show/hide the segments in all opened tour charts, closing the tour segmenter will hide the segments in the charts | | Save | with the Save action the elevation gain for the selected tour can be saved |
Save elevation gain The computed elevation gain ist displayed beside the Save button: - computed elevation gain for the whole tour by using the selected algorithm and their options
- elevation gain which is currently saved for the tour
- Save action: saves the computed elevation gain into the tour
Altitude difference columns The altitude difference columns have these values: - shows the altitude difference between segment-start and -end
- show the maximum altitude difference within the segement
(these values are displayed when the tour segmenter is using the algorithm Ascending/Descending, otherwise they are set to 0)
