Overview

880 Protection Civile units across every wilaya, straight from the DGPC's own dataset (dgpc.dz), each unit with an Arabic name, an address, phone and fax, a status tier (statut), and a real DGPC coordinate. This is an official-primary dataset: the DGPC is the authoritative "this unit exists here" source.

Installation

npm install @geoalgeria/protection-civile

Quick start

import {
  units,
  unitById,
  unitsByWilaya,
  unitsByStatut,
  metadata,
} from "@geoalgeria/protection-civile";

units().length; // 880

// Everything in Alger (code 16)
unitsByWilaya(16).length;

// One tier, and a single record
unitsByStatut("UNITE PRINCIPALE").length;
unitById("16-001")?.commune;

metadata().wilayas_covered; // 69

What you can build

• A civil-protection / fire & rescue locator or map layer for Algeria
• An emergency-response coverage analysis by wilaya
• A base layer to join against live DGPC bulletins

What's inside

Dataset	Count	Coordinates	Notes
protection-civile	880	all 880	DGPC (dgpc.dz), geocoded, post-2026-reform wilaya linkage

By status tier (statut): UNITE SECONDAIRE 444 · POSTE AVANCE 146 · UNITE DE SECTEUR 132 · UNITE PRINCIPALE 62 · SIEGE DE DIRECTION WILAYA 58 · POSTE DE SECOURS ROUTIER 20 · UNITE MARINE 15 · U.N D'INSTRUCTION ET D'INTERVENTION 1 · DIRECTION GENERALE 1 · CELLULE DE SECURITE 1

Every unit carries tel, fax and address; 780 communes were matched by name, the rest by nearest centroid.

How the data is built

Downloaded from the DGPC's own GeoJSON (dgpc.dz/dgpc2/unite.geojson). Coordinates come from each feature's decimal x/y. wilaya_code is derived by point-in-polygon against the repo's 69 post-2026-reform wilaya boundaries, then reconciled against the DGPC's own cod_wilaya (which is pre-reform, codes "01".."58"): units now inside the 11 new 2026 wilayas carry their correct new code (geometry 59..69), but where geometry and the DGPC code disagree among pre-reform codes, a border unit misfiled by a ~150 m-simplified outline, the DGPC's official code wins and the commune is re-matched there. The DGPC code is preserved verbatim in refs.dgpc_wilaya as a receipt. Commune is best-effort, the Arabic commune_1 name is matched against the geoalgeria commune set within the resolved wilaya (nearest-centroid fallback). Rebuild with npm run fetch (or --cache to rebuild from the cached pull). See research/protection-civile/ in the monorepo.

Known risk, carry keys. Stable public ids are carried across rebuilds by the DGPC objectid (refs.dgpc), an ArcGIS-style surrogate the DGPC could renumber on their side. The rebuild logs a carry-hit count; a sudden drop from ~880 means the surrogate was renumbered, diff the ids before committing rather than letting them re-mint.

On accuracy & coverage

This is the DGPC's complete published unit network, 880 units. Every unit carries a real DGPC coordinate; a few coincident points are honestly marked approximate (geo_precision), the rest exact. There is no French name in the source, so name_fr is not derived, nothing is machine-translated. Commune is name-matched best-effort; wilaya is boundary-derived, then cross-checked against the DGPC's own code: conflicts among pre-reform codes (a border unit misfiled by a simplified outline) resolve to the DGPC's official code.

The DGPC's original cod_wilaya is pre-2026-reform and is kept only as refs.dgpc_wilaya. Use wilaya_code (the geometry-derived, post-reform code) for any wilaya join.
