OSM-Lücken als Aufgaben

The viewer reads names, addresses, storeys and listing from OSM and heights and footprints from the official LoD2. Where the two disagree or OSM is silent, the viewer guesses (storeys and windows from the height, ADR 0010) or shows a nameless building. Those gaps are tasks for mappers — people who look on site or on sources OSM may use. This skill finds and lists them; it never edits OSM, not even an obvious one: OSM's import and automated-edits rules forbid it, and a hint is not a survey.

Run

The Stadtwissen must be published (bun dev or bun run build once, or bun scripts/prepare-sites.ts — without arguments: with one site it prunes the others' public/data).

bun scripts/osm-gaps.ts dresden            # one site: run it for each
bun scripts/osm-gaps.ts dresden --top 30

It writes osm-gaps/<site>/ (gitignored): one GeoJSON per kind — wahrzeichen-ohne-name, geschosse-fehlen, denkmal-ohne-name — each feature a point with its instruction and links (the shape MapRoulette takes for a challenge), and aufgaben.md, the counts and the first N of each kind, highest first.

Report

1. Run it for every committed site (data/<site>/ exists).
2. Compare with last month's comment on the open issue labelled osm-gaps in mdugue/bridge: how many closed since (mappers did them), how many new. A gap that closed is the good news; say it first.
3. Comment once, in German: per site the counts and their change, the first ten of „Wahrzeichen ohne Namen“ and „Geschosszahl fehlt“ with their links, and how to make a MapRoulette challenge from the GeoJSON (the maintainer uploads it; it is his account). Create the issue, titled „OSM-Lücken“, only if none is open.
4. Something the twin itself gets wrong (a landmark matched to the wrong building, a listed building that is not one) is a finding about the bake, not a mapper's task: name the bake step (landmarks.py, osm_buildings.py) in a line of its own.

Never

• edit, upload to or comment on OpenStreetMap, or create a MapRoulette challenge yourself;
• copy anything from Google Maps/Street View into a task (OSM may not use it): the tasks' sources are the official LoD2 and Wikidata.
