# Offline place directory and map

The PRL directory is an original curated selection of 600 actual place/POI facts, covering all 25 Sri Lankan districts. It is not copied from a cab/rental directory. Names and WGS84 coordinates came from © OpenStreetMap contributors, via Geofabrik's Sri Lanka extract downloaded 2026-11-05: https://download.geofabrik.de/asia/sri-lanka-latest.osm.pbf . OSM data is licensed under ODbL 1.0, **not CC0**: https://www.openstreetmap.org/copyright and https://opendatacommons.org/licenses/odbl/1-0/ . This curated derivative database is supplied under ODbL 1.0. Individual record source identifiers and language provenance are in research/M8-GAZETTEER-AUDIT.json. Node positions are source points; way positions are approximate mean-vertex centres, never an entrance/routing guarantee.

District assignment uses point-in-polygon checks against OCHA's Sri Lanka district boundaries via geoBoundaries gbHumanitarian, revision9469f09, https://github.com/wmgeolab/geoBoundaries/tree/9469f09/releaseData/gbHumanitarian/LKA/ADM2 (CC BY3.0 IGO; OCHA/Survey Department Sri Lanka). No boundary geometry is shipped in the gazetteer. Check exact pickup with the customer, especially at district borders.

The small Sri Lanka outline is the main island from Natural Earth 1:10m Admin 0 data (v5.1.2), simplified to 130 points: https://www.naturalearthdata.com/about/terms-of-use/ (public domain), https://github.com/nvkelso/natural-earth-vector/blob/v5.1.2/geojson/ne_10m_admin_0_countries.geojson . Only a simplified outline is shipped, not a road map.

English names/coordinates/types are factual source records. Weliwita (Colombo district, Kaduwela area; 6.9313, 79.9627) is GeoNames record 1223618, downloaded from https://download.geonames.org/export/dump/LK.zip on 2026-11-05, © GeoNames, CC BY 4.0 (https://www.geonames.org/export/). This is an area point, not the client’s entrance. Compact public IDs map to original source IDs in the audit. Western Province has 329 entries. Sinhala/Tamil tags are retained where available; otherwise original draft transliterations/translated generic descriptors are supplied, with explicit draft flags. The UI retains the locale draft disclosure. These are search aids, not certified postal addresses or fluent-language translations. Input may always be free text. Common city/airport aliases are original editorial additions. No fictitious hospitals, airports, malls or capacities were generated.

Gazetteer loads from the same origin on first place-field focus. No runtime geocoding/routing/places service, trackers, cookies, localStorage or third-party API requests are added. Geolocation requires the customer's explicit button press/browser permission; coordinates remain in memory and are used only in the editable message and its approximate visual/estimate. No location is written to disk or browser storage. Map links are text links in the manual draft.
