Slope gradient values?

morgan shared this question ago

Answered

When locus colors a track with a gradient, I believe it has set numeric values in the software to represent actual slope numbers.

Having ridden this track (Ophir pass in CO) and went down 6 times in 1 mile I know it intimately as I lay there in the rocks gasping for air at 11,000 feet.

I do not believe you can enter these values.

Here is my guess as to the colors of the slope:

below 30 degrees=base color, oranges

30=light red

35=red

40=dark red

Does anyone know the correct values used?

In Locus Map (and similar OSM-based engines), the slope gradient is typically calculated as a percentage (%) rather than degrees, which is a crucial distinction for your calculations.

Thanks for the response. if percentage that is "relative" to the entire track. I believe Locus does not do it that way. it is much better to calculate it "Absolute" with values? Can a DEV please answer this definitively???

Hi,

Yes, the slope values are calculated as a percentage.

The coloring on the map is based on the full range of the track. First, the app finds the minimum and maximum slope values. Then, it sets the range so that "0" is correctly in the middle. Finally, it computes the colors. You can set a custom slope range to avoid this dynamic range entirely. Edit the track line style and click the "Pencil" icon on the right. Hope this helps!

Thanks. I had never seen the sub menu change to manual then you can enter % values...but it is only % values so you are doing the same exact same compute just changing the range. What I was hoping for are absolute slope values assigned to colors so level of difficulty is more standardized not based on only the current track.
