Pipeline

High-resolution LiDAR point clouds are processed into digital terrain models (DTM). Slope angles are then calculated, color-coded, and rendered as tiles for zoom levels 10–16. Three resolution tiers are available: 2 m (UHD), 3 m (HD), and 5 m (MD).

LiDAR → DTM → Slope → Color Coding → Tiles

Color Scale

Slope angles are color-coded: yellow from 30°, through orange and red to magenta in very steep terrain. In extreme terrain, the color shifts to violet and blue — where fall risk dominates.

Tiles with custom color scales can be provided on request.

Hosting

All tiles are stored as static PNG files on Cloudflare R2 — a global CDN with over 300 locations worldwide. There are no dynamic servers: everything is static and fast.

API

Tiles are available via a standard XYZ schema and can be integrated into Leaflet, MapLibre, QGIS, and other mapping applications. Access is granted on request. Details are governed by the Terms of Use.
