Illustrate the dip of the segments of the tracks

Gaël Mauron shared this idea 9 years ago
Gathering feedback

Hi Menion,


While I am preparing a tour (mountain bike or hiking tour), I've noticed that it is difficult to appreciate on the profile/elevation graph the dip of segments of the tracks (for instance 30°, 45°,…), and thus the difficulty of the tour. This especially because the scale change in order to use the total space of the window (which is good). Therefore it could be an idea to draw the segments (lines between two points) in different colours in function of the dig of the segment on the elevation graph (and why not on the map).


For example :

Green < 10°

10° < Orange < 20°

20° < Red < 30°

Blue > 45°

Good day Gael,


I think, that such feature is already available in Locus ;)


Tap on track, in first tab is style, how track is drawn. Tap on this style, disable! "Style from folder" and here is advanced settings for styling your track on map. Between all options is also possibility to colorize track by altitude values.


If your track do not have altitude values (manually planned), use "Fill altitude" function in bottom menu of track on main screen.


Works?

Hi Menion,


I haven't seen that you answered to my question…Oups!


Thanks for your answer. I did try the option to colorize depending on the altitude and it works well. Nevertheless I meant to colorize the track depending on the dig of the slope (between two points). I discussed this with friends and they told me that it would be also very interesting for ski tours planning. Because avalanche's risks depend on the dip of the slope (especially < 30°, <35°, <40°).


Let me know if you integrate among the other options.

Hello Gael,


if I undnerstand correctly, this option is also there. Try to colorize not by "Altitude" option but choose "Change of altitude". It should be what you are looking for.

Hi Menion,


Thank you

for your quick answer. You're right, it is what I was looking for! Just

a last question : Where can I find the legend of the colors. For exemple :


Green < 10°


10° < Orange < 20°


20° < Red < 30°


Blue > 45°


Would it be possible to colorize the profile/elevation graph

in the same way? This, because it is difficult to appreciate on this graph the

dip of the segments of the tracks. This especially because the scale change when

you turn the device from the horizontal position to the vertical one.


I would like to tell you again how much I appraciate your

App and how good and serious is the support you provide us.

Gaël

Hello,


you are welcome :)


Legend for a coloring isn't anyway in Locus. You may vote for this feature here in this topic http://help.locusmap.eu/topic/ability-to-view-somehow-small-legend-for-coloured-tracks .


Coloring of chart also isn't a simple task for now, but I'll keep it in my mind. Thanks for idea.

Hi Gael!

Let me also point you to this idea: http://help.locusmap.eu/topic/slope-shading-in-different-colours-30-35-40

This would also help a lot with planning bike & ski trips, as you could see the (dangerous) slopes directly on the map...

Hi Menion,

Thanks

for the answer. I actually don't need it in Locus but could I find the legend anywhere

(especially for altitude difference, dip of the slopes) or should I recalculate it

for each color?

Legend is always unique. It is simply computed relative to min and max values in current track

Hi Menion,


Therefore it means that in the "Change of altitude" mode for the same dip of the slope the color could be once dark red for example if the altitude gap is 10 meters between two points (because I was quick) and then blue because the altitude gap is 5 meters (because I was slower)?!?


From my point of view it would really make sense to create a new "Dip of the slope" scale. This scale would have the big advantage to be fixed between 0° and 90° anyway and really usable! You could create a 10° step with nine different colors for example. The formula would be :


Dip [°] = tan-1(Delta_Atlitude[m]/Delta_Horizontal_Distance[m])


Let me know if you will create it.

The existing implementation is some how a relative mode, whereas what Gaël requests is more an absolute mode.

Both modes make sense in my opinion.

Hi Menion,


I've seen

that you updated something in the new release around the "altitude

change" option. Nevertheless I haven't seen the option "dip of the

slope". Do you think about implementing it? From my point of view it would

be a very interesting (and important) feature for a lot of people who plan tracks

(Mountain biking, ski tours, etc).


Let me know

if you plan to implement it.

Gaël

Hi Menion,


How are you doing? I guess that you have

a lot of new features to implement but do you have any planning to consider

implementing the "dip of the slope" option for the track colour?


Let me know.

Good day Gaël,

we made after long discussion with guys in this topic: http://help.locusmap.eu/topic/improve-change-of-altitude-track-style-mode a lot of, more or less, minor modifications in coloring gradient of track on a map. And to be true, this is maximum time I'm able to invest into this topic now, as I'm sure, final implementation is quite useful to give general overview about gradient on a track.

Hi Menion,


Do you have any news about my above proposal?

Hello Gael, as I wrote above, there is currently no plan to invest more time into this feature, sorry.

Hi Menion,

I find your App amazing and I recommended it to a lot of friends (who bought it by the way).

Nevertheless I don't understand why you don't want to implement this very useful functionality. It is not right that the implementation is time-consuming. The formula is simple and is as following.

Dip [°] = tan-1(Delta_Atlitude[m]/Delta_Horizontal_Distance[m])

Please reconsider my proposal.

Good day,


compute of values is of course quite easy so it may be a work on a few hours, anyway coloring of chart based on these values is a lot long-term task, because chart is currently made for a single coloring.


As I see by number of votes of this topic, there is not so big interest in this feature. So sorry, for now this is not planned, as I wrote before.
