Contour
Discover the world's most iconic driving roads — scenic coastlines, mountain passes, rally stages, and historic circuits, mapped from real OSM geometry.
Driving enthusiasts collect legendary roads in scattered YouTube playlists and forum threads. There was no single place to browse iconic routes with real map geometry, categorize them (rally / scenic / circuit / gaming), and save the ones you actually want to drive.
Built a content-first mobile-shaped web app with a strong hero, location-aware 'roads near you', and tag-based filtering. Routes are imported from OpenStreetMap via a custom Overpass importer that matches by road ref and stitches the longest connected polyline — so the map geometry is real, not hand-drawn.
A browsable library of curated driving roads with Explore, Saved, Profile, and an admin review flow behind Supabase auth + role-based RLS. The OSM importer turned route curation from manual GeoJSON work into a repeatable script.
- Mobile-first layout with bottom tab nav (Home / Explore / Saved / Profile)
- Geolocation-aware 'Roads near you' with graceful fallback when permission is denied
- Multi-tag filtering: rally, scenic, circuit, city, gaming
- Route detail pages with real OSM polylines and 'Ride Mode' full-screen view
- Saved routes per user, Google sign-in, admin role gated by Supabase RLS
- Custom Overpass / OSM importer script for repeatable route ingestion
