@geoalgeria/mosquees

The mosques of Algeria, as data you can install.

20,759 geocoded mosques across all 69 wilayas of Algeria, every one with coordinates, most with Arabic and/or French names, and commune/wilaya linkage. A community-maintained composite of Wikidata and OpenStreetMap, framed honestly against the Ministry of Religious Affairs (MARW) national count of ~18,449. Shipped as JSON, CSV, GeoJSON, and TypeScript. Part of GeoAlgeria.

npm install @geoalgeria/mosquees

import mosquees from "@geoalgeria/mosquees";

const all = mosquees.mosquees();   // 20,759 geocoded mosques

// Mosques in a wilaya (joins GeoAlgeria's wilaya_code)
const inSetif = all.filter((m) => m.wilaya_code === "19");

// Only the named ones, with a French label
const named = all.filter((m) => m.name_fr);

What you can build

• Mosque maps & locators – coordinates on all 20,759 records, ready for a map or distance sorting.
• Bilingual directories – 15k+ Arabic names and 7k+ French names, side by side.
• Coverage analysis – count or rank mosque density per commune/wilaya across the whole country.

What's inside

| Dataset | Count | Coordinates | Notes | | --- | --- | --- | --- | | Mosques | 20,759 | ✅ all | 19,783 named, 69 wilayas |

By source

| Source | Count | Meaning | | --- | --- | --- | | wikidata | 13,200 | from Wikidata only | | wikidata+osm | 5,897 | in both, matched within ~150 m (OSM lends a French name / denomination / refs.osm) | | osm | 1,662 | mapped in OpenStreetMap, not yet in Wikidata |

This is a composite, not an official registry. Wikidata gives near-complete national coverage (~19k geocoded mosques, close to the MARW figure of ~18,449); OpenStreetMap adds precise coordinates, French names, denomination, and mosques Wikidata lacks. Counts move as both projects are edited, each rebuild reflects the current state of the sources.

Formats

The npm package ships the JSON (importable directly):

import mosquees from "@geoalgeria/mosquees/data/mosquees.json" with { type: "json" };
// or via CDN, no install:
// https://cdn.jsdelivr.net/npm/@geoalgeria/mosquees/data/mosquees.json

The loaders and record shapes are fully typed, TypeScript definitions ship in the package:

import mosquees, { type Mosquee } from "@geoalgeria/mosquees";
const all: Mosquee[] = mosquees.mosquees();

CSV and GeoJSON are in the repo under data/ and bundled in every GitHub Release:

data/
  mosquees.json              # 20,759 mosques (array)
  metadata.json              # sources, counts, coverage, updated
  csv/mosquees.csv           # repo + Release bundle (not in npm tarball)
  geojson/mosquees.geojson   # Point features

Record shape

{
  "id": "16-0914",
  "name": "مسجد عبد الحميد بن باديس",
  "name_fr": "Mosquée Ibn Badis",
  "name_ar": "مسجد عبد الحميد بن باديس",
  "wilaya_code": "16",
  "commune_code": "1607",
  "commune": "Casbah",
  "lat": 36.779365,
  "lng": 3.05949,
  "geo_precision": "approximate",
  "geo_method": "osm_relation",
  "source": "wikidata+osm",
  "refs": {
    "wikidata": "Q28717404",
    "osm": "relation/15870867"
  },
  "denomination": "sunni"
}

id is a stable {wilaya_code}-{seq} key synthesized by GeoAlgeria, unique within mosquees.json. refs.wikidata and refs.osm link back to the upstream objects. name is the best available display name (French preferred, else Arabic) and is null for the unnamed OSM points. wilaya_code joins to GeoAlgeria's wilaya_code.

Commune/wilaya linkage is derived, not from the sources. Neither Wikidata nor OSM carries Algerian administrative codes. GeoAlgeria attaches wilaya_code, commune_code, and commune by a nearest-centroid join against the geoalgeria commune set. Wilaya assignment is effectively exact; commune is best-effort (centroid proximity, not polygon containment).

Need the administrative divisions too?

For wilayas, dairas, and communes, use the main geoalgeria package, it's how you turn a mosque's commune_code into a polygon or centroid. Use @geoalgeria/mosquees when you only need the mosques.

Source & method

Run npm run fetch to regenerate every output. It:

1. queries Wikidata (SPARQL) for every item that is an instance of a subclass of mosque (Q32815) located in Algeria (P17 = Q262) with a coordinate (P625), the comprehensive base;
2. queries OpenStreetMap (Overpass) for amenity=place_of_worship + religion=muslim inside Algeria;
3. merges them, an OSM mosque within ~150 m of a Wikidata mosque is folded into that record (lending its French name, denomination, and refs.osm); OSM mosques with no match become their own records;
4. attaches commune/wilaya by nearest commune centroid.

Raw source pulls are cached under research/mosquees/.
