description	Download TILDA Geo dataset exports (GeoJSON, GPKG, FGB) from tilda-geo.de by bbox. Use when the user asks to export or download map data, bikelanes, roads, parkings, or other export tables for a bounding box.

TILDA export download

Download clipped exports from production via /api/export.

Before downloading

1. Bbox — ask the user for a GeoJSON-style bbox: [minlon, minlat, maxlon, maxlat] (WGS84).
2. Dataset — ask which table (e.g. bikelanes, roads, parkings). Allowed values: exportApiIdentifier in app/src/routes/api/export.$regionSlug.$tableName.ts.
3. Format(s) — ask which format(s). Allowed values: app/src/server/api/export/ogrFormats.const.ts (geojson, gpkg, fgb).
4. Output path — ask where to save files (create the directory if needed).

Always use region slug deutschland.

Download

Read ATLAS_API_KEY from repo root .env — do not source .env (some values break the shell):

ATLAS_API_KEY=$(grep '^ATLAS_API_KEY=' .env | cut -d= -f2- | tr -d '"')

URL pattern:

https://tilda-geo.de/api/export/deutschland/{table}?minlon={}&minlat={}&maxlon={}&maxlat={}&format={format}&apiKey=${ATLAS_API_KEY}

Example (bikelanes, geojson + gpkg):

OUTDIR=~/Downloads/my-export
BBOX="minlon=7.765700&minlat=49.315500&maxlon=10.585600&maxlat=51.646700"
BASE="https://tilda-geo.de/api/export/deutschland/bikelanes"

mkdir -p "$OUTDIR"
curl -fSL --retry 3 -o "$OUTDIR/bikelanes.geojson" "${BASE}?${BBOX}&format=geojson&apiKey=${ATLAS_API_KEY}"
curl -fSL --retry 3 -o "$OUTDIR/bikelanes.gpkg"    "${BASE}?${BBOX}&format=gpkg&apiKey=${ATLAS_API_KEY}"

Large bboxes can take 30s+. Use curl -f so HTTP errors fail loudly. Response filename is in Content-Disposition (e.g. bikelanes_2026-07-19.geojson).

Auth note

apiKey bypasses session/membership checks (compareApiKeyTimingSafe). Without it, the route requires region membership or admin.
