Track color based on altitude?
Answered
Hello, i've just discovered Locus Maps and i'm testing the free version.
i would like to use it for MTB rides and i'm not sure if it's possible to have the track (not the map!) colored by slope levels... it's very useful function (seen it on other map aps)
is this option available? (tried a search on forum but found only old discussions)
Thx and sorry for my english :P
The same question
Somewhere on this forum, there's an Idea for improving how a track's altitude is displayed (but I can't find it).
If I'm not mistaken, it currently works in "relative" mode. It shows the steeper portions, relative to the less steep areas in the track. In other words, the part you see colored "red" isn't necessarily very steep but just steeper than other parts such as the ones shown in "green". If everything is shown in green, then it means most of the route has about the same steepness. It sounds like you want to emphasize the changes in gradient. I'm not certain but I don't believe Locus Map offers this ability.
The problem with "relative" mode is it is not useful if you wish to compare one track to another. The Idea was to provide an option to have it work in "absolute" mode. In this mode, red would represent a specific range of gradients (like 30-35%). In absolute mode, the color is not relative to other parts of the track but to a fixed scale. This allows you to compare one track to another.

Yes, the option is available and it is called "Mode" in the track's "Line Style".

Awesome thanks!
Quite "hidden" option but once you know it... :P
Seems really nice program so far, i'll test it in next rides, would buy Pro version if expectations will be satisfied!

Update: tried the "change of elevation" that, if i'm understanding it right, should color the track more towards red if direction is bringing me uphill or towards blue if downhill, but seems not working too well most parts are just green despite the zoom....
The same track loaded in oruxmaps shows altitude variation way better so it's not a GPX file problem.
Is there some other setting i'm missing?
thanks a lot

Oh so not available atm.... :(
Thx for the explanation!

I support this idea of absolute rendering

See coloring mode. In menu select display by slope than tap the pencil -> opens the relative/absolute menu.

Great! Just another little question: do colors by slope follow track direction? i mean the same track should change colors not only by slope but even by direction
Thanks

Seems to me it is still relative ... I am using Slope 5%-max on these 2 tracks, and the colours are quite different ...

Michal, not sure I understand your explanation, but even for more complex tracks, I don't get the same colours for parallel sections of different tracks. My expectation would be that all sections starting at elevation x and ending at elevation y should be of a the same colour, right?

Hello Gergy,
as Michal already wrote: "test it on some real tracks or routes - two point routes may sometimes return different values".
My test, first image with relative slope values and second with defined limit 0 - 20%. All is correct. App do some optimization of altitude values and in case of less then, let's say 10 points, values may not be reliable. An algorithm needs more points to get some usable results and have to 2 points on the whole hill is possible maybe on the couch, but definitely not in real terrain.

OK, thanks for the explanation
