Munro Bagger

A map-first web app for tracking climbs of Scotland’s 282 Munros. Browse every Munro on a topographic map, open one to see its details and routes up, and tick it off with a date. Your progress lives in the browser (localStorage) — no login.

Status: v1 prototype. All 282 summits are plotted; route data has been derived for a sample of hills (Ben Lomond, plus others in progress). The rest show an honest “no routes sourced yet” state with a link out to Walkhighlands.

Features

• Map — all 282 current Munros on an Esri topographic basemap (MapLibre GL). Blue = to do, green = bagged, gold ring = has route data.
• Details panel — height (m/ft), height rank, grid reference and OS sheet.
• Routes — where derived, real route lines follow the OpenStreetMap foot network, with distance, ascent, Naismith time, and a confidence dot (green = derived from mapped paths, amber = approach approximate, red = no mapped path).
• Tick-off — bag a Munro with a date; the “X / 282” counter and progress bar update.
• Filter — All / To do / Bagged.
• Export — download your tick list as CSV or JSON.

Run it

Any static file server works — the app is plain HTML/CSS/JS with no build step:

cd munro-app
python -m http.server 5178
# open http://localhost:5178

Data

• Munro list — munro-app/data/munros.geojson, derived from the Database of British and Irish Hills munrotab v8.0.1 (current SMC classification, 2021 == "MUN" → 282), with OSGB36 eastings/northings reprojected to WGS84. Licence: CC-BY / OGL.
• Routes — munro-app/data/routes.json, derived from the OpenStreetMap foot network (ODbL) by shortest-path from trailhead to summit. See munro-app/data/derive_routes.py.
• Coverage sense-check — munro-app/data/coverage_check.py / coverage_results.tsv: OSM path coverage across contrasting Munros.
• Basemap — Esri World Topographic tiles.
