Gentleness score
Distance, gain, max grade and route shape are weighted first because they can be calculated consistently from geometry and elevation profiles.
Methodology
How Gradient Trail earns trust
The site is designed around calculated terrain metrics, transparent sources and conservative language where safety or accessibility could be misunderstood.
Access signal
Wheelchair, smoothness and surface tags are shown only as signals when available. The site never promises current accessibility.
Source attribution
Geometry attribution belongs to OpenStreetMap contributors. Elevation attribution is separated for USGS 3DEP and Copernicus DEM sources.
