TravelMappingUserMap

Lightweight browser app that renders a Travel Mapping user's traveled highway segments on a Leaflet map.

This is deployed as a GitHub page! Access the app here: https://yqt1001.github.io/TravelMappingUserMap/

What it does

• Takes a Travel Mapping username.
• Loads compact local per-user JSON generated from the TravelMapping master graph.
• Draws that user's traveled graph.
• Supports shareable links with ?user=<username>.

How it works (high level)

1. Generate compact data/tmg-users/<username>.json from the traveled TMG file.
2. Enter that username in the app.
3. App decodes and renders polylines in batches (worker-enabled when available).

Run locally

From the project root:

1. Generate local user data:
   • node scripts/build-tmg-user-json.mjs --user=<username>
2. Start a local web server (not file://):
   • python -m http.server 8080
3. Open:
   • http://localhost:8080

Advanced build script details are in scripts/README.md.
