Provjera nagiba šumskih cesta

Izračunajte nagib iz dvije točke ili iz popisa točaka rute, a zatim označite opasne segmente.

Izrađeno za brze provjere na šumskim cestama, skider trasama i trasama za kabelsko izvlačenje širom svijeta.

Safety Notice

  • This tool is for quick slope checks. Local conditions, soil, surface condition, vehicle type, load, and machine method can change the decision.
  • Whether it is a forest road, skid trail, or cable yarding route, final decisions should follow local standards and on-site checks.
  • Cable yarding cannot be judged by slope alone. Check skyline and equipment conditions separately.
  • Hazard labels are warnings, not proof of approval or compliance.

How to Use

  1. Choose either pair mode or route-point-list mode.
  2. Choose a distance unit and a profile.
  3. Enter the distance and elevation change, or enter the point list.
  4. Review the hazard segments, then copy the result or the share URL if needed.

Output Highlight hazard segments in the table and profile chart

Pojmovnik

grade

The ratio of elevation change to horizontal distance. Percent is grade x 100.

chainage

Cumulative horizontal distance along the route. It becomes the reference for route-point segments.

skid trail

A trail used to move felled logs to the landing. Terminology varies by region.

cable yarding

A yarding method that uses a cable or skyline system. Slope matters, but slope alone is not enough.

Formule

grade = rise / run
grade% = grade * 100
angle° = atan(grade) * (180 / π)
1:n = 1 : (run / |rise|)
total ascent = Σ max(Δelevation, 0)

Česta pitanja

Why do you use horizontal distance?

Because slope is defined against horizontal distance, not route length or surface length.

How do I enter chainage for route points?

Enter cumulative horizontal distance in increasing order. Each point must be greater than the one before it.

How far does metric/imperial support go?

The tool switches the distance and elevation units. The calculation itself stays the same; only the display is localized.

Are the thresholds universal?

No. Profiles are starting values. Switch to custom and tune them for the local conditions and machine method.

Can I use it for cable yarding?

Yes, for organizing slope data. It is not a substitute for skyline design or equipment design.

Važne napomene

  • Profiles are starting points. They are not fixed operating standards.
  • Enter route points in increasing chainage order. If the order breaks, segment slope calculations break too.
  • GPS or map auto-import is not part of v1. If needed, clean the data elsewhere and paste it in.
