# GreenRah
> GreenRah: The cooler way. Shade-aware Heat Smart walking routes and gentler Accessible paths.

GreenRah is a pedestrian routing product for hot cities, starting with Lisbon. Six live data layers (weather, solar position, 3D shadows, elevation and slope, walkable network) fuse in the Thermal Comfort Engine into one street score, then a safer walk. Built on validated science, not assumptions. Public pages are the marketing site, the User Guide, and the map app. Shared trip URLs that include from/to coordinates are session state for a walk, not separate pages.

Prefer these links over scraping the live map, tiles, or APIs.
