# Introduction

> A ready-to-render map view of the last meters of a delivery.

The **Last Meter Visualisation** API returns, for one of your deliveries, a ready-to-render
picture of the *last meters* of the delivery: where the driver **parked**, the **entrance** that
was used, the **walking path** between them, an optional intermediate **waypoint**, and the
**building** the entrance belongs to.

You request it for a single delivery stop — by giving the **entrance** and **parking** address
identifiers (they may be the same id, or two different ids) — and get back:

* a **GeoJSON `FeatureCollection`** you can drop straight onto a [MapLibre](https://maplibre.org/)
  or [Mapbox](https://www.mapbox.com/) map — the styling hints (colours, line widths, dashes) map
  1:1 to map layer styles, and
* optionally a **rendered PNG image** (`raster`), so you can show a thumbnail without running a
  map renderer yourself — either transparent (to overlay on your own map) or on a street basemap.

## When to use it

* Plot the last-meter geometry of a delivery in your own dashboard or driver app.
* Embed a small map thumbnail of a stop in an email, report or ticket.
* Give dispatchers a quick visual of *where exactly* a parcel was delivered.

## What you get

| Element          | Description                                                      |
| ---------------- | ---------------------------------------------------------------- |
| **Entrance**     | The detected door / delivery point for the address.              |
| **Parking**      | Where the driver parked the vehicle.                             |
| **Waypoint**     | An optional point along the walking route.                       |
| **Walking path** | A dashed line from parking to entrance.                          |
| **Building**     | The building footprint the entrance belongs to (when available). |

All coordinates are returned in **EPSG:4326** (WGS84 longitude/latitude).

## Authentication

Every request is authenticated with your **`x-api-key`**. The key identifies your account, so you
only ever receive your own data — there is no account or customer parameter in the request. Your
key and the base URL are provided by your truemetrics contact.

<Info>
  The identifiers you pass are the same address identifiers you send to truemetrics as metadata
  (your `id_address` / merge id). The entrance and parking may use **different** identifiers — pass
  each to its own parameter (`identifier_entrance` / `identifier_parking`).
