BGMountains Garmin IMG → native OsmAnd OBF — v0.95

This is the integrated source release. It replaces the v0.92/v0.93 Python pipeline and v0.94 standalone CSVs. Do not combine scripts from older ZIPs: those versions accept different flags and do not apply the 79 name-conditional rules. This archive has one POI config and one line config.

Quick start (Ubuntu/Debian)

sudo apt update
sudo apt install -y cmake g++ make libpng-dev libsqlite3-dev python3 openjdk-21-jre-headless unzip
unzip BGMountains-garmin2osm-v0.95-integrated.zip
cd BGMountains-garmin2osm-v0.95

Use exactly this from the release root (where scripts/ and config/ are):

nohup python3 scripts/build_bgmountains.py \
  --img "$HOME/gmapsupp.img" \
  --poi-config config/BGMountains-native-poi-mapping-v094.csv \
  --line-config config/line-mapping.csv \
  --out bg-mountains-v095-build \
  --download-creator \
  --jobs 8 \
  --java-opts '-Xms512M -Xmx25G' > bg-v095.log 2>&1 &

The --poi-config and --line-config arguments are implemented and tested. Other supported flags: --creator /path/to/OsmAndMapCreator, --bbox W,S,E,N, --prepare-only, --keep-raw, --template, --attach-routes, --disk-headroom-gb N, --ignore-disk-check, --jobs N (default 1).

Check your actual disk space first. Full-country MapCreator compilation has previously required over 25 GiB of temporary disk space in addition to the source OSM (6+ GiB) on your machine. The script uses a conservative estimate max(2 GiB, 5 × native-OSM-size + 1 GiB), unless --disk-headroom-gb requires more. These figures are not upper bounds. Choose an output filesystem with generous free space. -Xmx25G controls heap RAM, not disk usage.

Safe regional test, no Java or extra download

python3 scripts/build_bgmountains.py \
  --img "$HOME/gmapsupp.img" \
  --poi-config config/BGMountains-native-poi-mapping-v094.csv \
  --line-config config/line-mapping.csv \
  --bbox '25.05,42.43,25.16,42.54' \
  --jobs 8 \
  --out ./regional-test \
  --prepare-only

Inspect regional-test/BGMountains-native.osm, semantic-audit.json, route-report.json, extract.log, translate.log, audit.log. The tool must exit nonzero on a failed conversion subprocess. You can instead pass an existing MapCreator with --creator ... (omit --prepare-only) for a small real OBF build.

Two editable configuration files

1. config/BGMountains-native-poi-mapping-v094.csv

1,871 base hex-code entries plus 79 name-specific exceptions (1,950 data rows). Columns include: code, source_count, legend_bg, legend_en, meaning_confidence, osm_tags, label_bg, priority, zoom_hint, action, note, examples, and optional name_contains. For conditional matching, set name_contains in an additional row with the same code. The matcher uses case-sensitive substring matching on the original Garmin name, with rules applied in file order after the base rule. replace changes the converter's semantic defaults; append retains previous tags; raw leaves unspecified features unclassified until private-map fallback; drop discards the feature.

The Python pipeline automatically creates cpp-poi-override.csv and cpp-name-labels.csv inside the build output directory. These are generated intermediates, not third and fourth user configuration files. There is no need to manually supply them or an icon pack to OsmAnd.

Important native examples:

• 0x6414: amenity=drinking_water;man_made=water_tap (legacy v18 dual classification); named dry sources such as (Сух.) remove drinking-water classification and get drinking_water=no.
• 0x6500: man_made=water_intake;amenity=water_point;drinking_water=unknown for private-map index compatibility, not evidence that its water is potable, available or accessible. Named shaft (Шах...) exceptions remove the compatibility alias.
• 0x6511: natural=spring (potability not asserted).
• 0x6402: building=yes by default, explicitly named Заслон or Хижа may become shelter/hut (availability/access not verified).
• 0x661d: agricultural structures remain agricultural unless specifically identified otherwise.
• 0x6600: keep numeric spot height ele=*, no fake settlement.
• Unknown POIs: place=locality, Неуточнено - <stable hash> if unnamed, and bgm:synthetic_fallback=place_locality; this private-map fallback does not guarantee Nearby POI indexing.

priority and zoom_hint are documented classification hints only. They do not force stock OsmAnd to show an icon at zoom 12. Likewise garmin:type remains a provenance tag, not a display rule. Only stock OsmAnd classifications and rendering apply to the resulting OBF.

2. config/line-mapping.csv

50 Garmin line types (20 currently have route_mode=relation, 30 preserve source geometry). Columns include Garmin code, legend, color, osm_way_tags, route_mode, osmc_symbol, network, confidence and priority. Selected source overlay segments are grouped into native type=route;route=hiking relations with osmc:symbol. Garmin source color is preserved as relation colour=*. The script does not create duplicate routable paths from decoration lines. Opt-in --attach-routes matches overlays to real existing path geometries, but can use significant memory; it is off by default. Existing physical path routing remains in the data. Exact phone-side color, icon and at-zoom visibility still depend on stock OsmAnd.

New or unknown IMG maps: generate configuration templates

python3 scripts/build_bgmountains.py --img /path/to/unknown.img \
  --out ./template-newmap --bbox '23.0,42.0,24.0,43.0' --template

Produces poi-mapping.TEMPLATE.csv and line-mapping.TEMPLATE.csv with observed types and sample coordinates. Fill them manually and run with --poi-config ./template-newmap/poi-mapping.TEMPLATE.csv and --line-config ./template-newmap/line-mapping.TEMPLATE.csv. Do not assume Garmin codes have the same meaning in unrelated maps. If you need a complete catalog for a new national map, generate its templates without --bbox, but this can require significant time and intermediate disk space.

Validation and provenance

cmake -S . -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j 4
ctest --test-dir build --output-on-failure

There is also tools/audit_osmand_poi_mapping.py, which takes the official version-matched OsmAnd poi_types.xml and produces a registry compatibility report, not a claim of final icon visibility:

python3 tools/audit_osmand_poi_mapping.py \
  --mapping config/BGMountains-native-poi-mapping-v094.csv \
  --poi-types /path/to/poi_types.xml \
  --report native-poi-audit.csv --json native-poi-audit.json

Tested, and NOT tested

• C++ Release build, 6 CTest test groups, conditional POI CSV generation, CLI options, and simulated MapCreator orchestration passed.
• Original 422 MiB IMG: regional --jobs 8 and serial preparation succeeded with identical 427 POI coordinate/name/tag records and 6 route relations.
• Separate region: (Сух.) water-tap conditional correctly produced man_made=water_tap;drinking_water=no, and no amenity=drinking_water.
• A real OsmAndMapCreator binary was not available here; its host was unreachable. The OBF orchestration unit test uses a mock, so native nationwide OBF compilation and phone rendering are not verified. Do not mistake that mock for real OBF validation.
