Color-coded tracks

In QV you can color-code a track according to:

  • Speed (horizontal or vertical)
  • Acceleration
  • Altitude
  • Slope
  • Age

Thus, color-coding is a highly valuable tool to analyse your trips.

To do so you can either plot the track(s) first and change the style options later on or you make your Trackcolor definitions first and then click the Show in map image1356962108.jpg icon.

You can access this function by marking the track(s) of interest in the QV X-Plorer and click the Style image1829313433.jpg icon.

Choose the Trackcolors tab and you will see the following window:

Several options are available in order to control the plotting style of the track:

Normal The track will be plotted as solid line with the selected Linestyle options.
Speed Altitude Acceleration Vertical Speed Alterating Slope Age of Trackpoint User The track line will be color-coded according to the magnitude of the selected parameter at the given trackpoint, i.e. speed or altitude, etc. When choosing Alterating, the track will be plotted as dashed line with the selected and background color alternating. Color selection is done in the Linestyle tab. When selecting the Slope option, the track will be color-coded according to the steepness of the track. Ascending and descending segments are shown in different colors. This option requires a DEM with an adequate resolztion. When selecting Age of Trackpoint, a time interval can be specified and the track will be color-coded according to the age of the trackpoint. Please note that this option is only meaningful during online mode and multitracking applications. The setting User is for user-defined color-coding definitions, a function which ist still to be completed.

Through the color bars on the righthand side of the window and the two sliders you can define the color range to be used and the colors which correspond to the minimum and maximum values. The minimum value has to be entered in the From field and the maximum value in the To field, respectively. By enabling the min/max Auto function, QV will automatically set the values for minimum and maximum according to the values in the corresponding X-Plorer column. The corresponding color spectrum is predefined and reaches from black over blue - cyan - green - yellow - orange - red to pink where black codes the minimum and pink the maximum value. When activating the Smooth gradient function, the colors will fade with a gliding spectrum instaed of using discrete colors.

Following you find some examples using the same track in a 2D map window (the function is also possible using a 3D window).
