Pair slope
Girdi profile=road distance=120m deltaElevation=18m uphill
Çıktı 15.0%, 8.5°, uphill 1:6.7, danger
Ormancılık Road Slope Denetleyici
Calculate slope from two puan or from a route puan list, then highlight hazardous segments.
Built for quick checks on forest roads, skid trails, and cable yarding routes around the world.

Safety Notice
- This tool is for quick slope checks. Local conditions, soil, surface condition, vehicle tür, 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
- Choose either pair mode or route-puan-list mode.
- Choose a distance unit and a profile.
- Enter the distance and elevation change, or enter the puan list.
- Review the hazard segments, then copy the result or the paylaşım URL if needed.

Glossary
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-puan segments.
skid trail
A trail used to move felled kayıts to the landing. Terminokayıty varies by region.
cable yarding
A yarding method that uses a cable or skyline sistem. Slope matters, but slope alone is not enough.
Formulas
grade = rise / run
grade% = grade * 100
angle° = atan(grade) * (180 / π)
1:n = 1 : (run / |rise|)
total ascent = Σ max(Δelevation, 0)
SSS
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 puan?
Enter cumulative horizontal distance in increasing order. Each puan 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 tasarım or equipment tasarım.
Important Notlar
- Profiles are starting puan. They are not fixed operating standards.
- Enter route puan 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.
