Route Packager — OsmAnd + Google KMZ

This package contains route_packager.py, a Python CLI for the scraped route archive tree in v4-scrape-675.tar.gz.

What it does

Scans the canonical downloads_by_hash/ folder by default, avoiding retry/failure duplicate folders.
Extracts ZIP, RAR, 7Z payloads.
Imports GPX, KML, KMZ routes directly.
Converts Garmin GDB to GPX when gpsbabel is installed.
Carries over scrape metadata from *.source.json into route descriptions and reports.
Carries over small text files into route descriptions.
Embeds image files into the KMZ and OSF package under media/... and references them from descriptions.
Writes machine-readable report.json and routes.csv for validation/pre-push review.

Outputs

Default command creates all of these:

<name>.osmand-tracks.osf — OsmAnd package/zip containing normalized GPX tracks.
<name>.all-routes.gpx — fallback aggregate GPX for OsmAnd if the OSF package import is not accepted by a particular build.
<name>.google-earth-maps.kmz — binary zipped KML package for Google My Maps / Google Earth.
<name>.google-earth-maps.kml — plain KML fallback.
<name>.report.json — full import/skip/warning report.
<name>.routes.csv — route list with source archive, point count, distance, bbox, etc.

Install extraction/conversion tools

The script itself is stdlib-only for ZIP/KML/KMZ/GPX. RAR and GDB need external tools:

sudo apt update
sudo apt install p7zip-full unrar-free gpsbabel

If unrar-free fails on some RAR versions, install one of unrar, unar, or bsdtar depending on your distro.

Full run

python3 route_packager.py \
  --input ./v4-scrape-675.tar.gz \
  --out ./route-out \
  --target both \
  --name bg-mountain-routes \
  --verbose

Google My Maps one-file safe mode

Google My Maps has a small uncompressed KML/KMZ import ceiling. For a single importable KMZ, use safe mode. It simplifies only the Google output; OsmAnd keeps full GPX detail.

python3 route_packager.py \
  --input ./v4-scrape-675.tar.gz \
  --out ./route-out-google-safe \
  --target google \
  --name bg-mountain-routes \
  --google-my-maps-safe

Manual geometry cap if needed:

python3 route_packager.py --input ./v4-scrape-675.tar.gz --out ./out --target google \
  --google-max-points-per-route 500 --google-lean-descriptions

ZIP-only validation without RAR tooling

python3 route_packager.py \
  --input ./v4-scrape-675.tar.gz \
  --out ./route-out-zip-only \
  --target both \
  --skip-rar \
  --name bg-mountain-routes-zip-only

Strict CI/pre-push mode

python3 route_packager.py \
  --input ./v4-scrape-675.tar.gz \
  --out ./route-out \
  --target both \
  --name bg-mountain-routes \
  --strict

--strict exits non-zero if RARs/GDBs fail to import.

Validation commands

python3 -m py_compile route_packager.py
python3 route_packager.py --input ./v4-scrape-675.tar.gz --out ./out --target both --skip-rar --name smoke
python3 - <<'PY'
from pathlib import Path
import zipfile, xml.etree.ElementTree as ET
out = Path('./out')
for name in ['smoke.osmand-tracks.osf', 'smoke.google-earth-maps.kmz']:
    with zipfile.ZipFile(out / name) as z:
        assert z.testzip() is None, name
ET.parse(out / 'smoke.all-routes.gpx')
with zipfile.ZipFile(out / 'smoke.google-earth-maps.kmz') as z:
    ET.fromstring(z.read('doc.kml'))
print('OK')
PY

Format note

There is no arbitrary custom binary route format for Google Maps imports. KMZ is the practical binary container because it is zipped KML and can include images/media. For OsmAnd, the script emits an OSF-style package plus a GPX fallback because GPX is OsmAnd's most predictable track import path.
