ChainShop TN

ChainShop TN, a 5-store network in Greater Tunis, uses the TMaps Isochrone API to calculate 15-minute reachable zones and detect neighborhoods without coverage. This data guides the opening of new sales points.

Code Example

// Zones de chalandise — API TMaps
const zones = await Promise.all(
  stores.map(async (store) => {
    const res = await fetch(
      'https://api.tmaps.tn/routing/isochrone',
      {
        method: 'POST',
        headers: { 'Authorization': 'Bearer YOUR_KEY' },
        body: JSON.stringify({
          origin:   { lat: store.lat, lng: store.lng },
          contours: [{ time: 15 }], // 15 min en voiture
          profile:  'driving',
        }),
      }
    );
    return res.json(); // → GeoJSON Polygon
  })
);

How It Works

🏪 Sales point geocoding

Each store address is converted to GPS coordinates to be accurately positioned on the map.

GET /geocoding/forward

🎯 Isochrone calculation

The Isochrone API generates a polygon representing the area reachable from each store within 15 minutes by car.

POST /routing/isochrone

🗺️ Visualization & gap analysis

Coverage zones are displayed on the TMaps map; areas without intersection reveal expansion opportunities.

GET /maps/tiles/{z}/{x}/{y}
