Reverse geocode a point

Reverse geocoding goes the other way: a longitude and a latitude become the nearest place. Results are ordered by real-world distance, not by relevance.

import { Unmap } from "@unmap/sdk";

const unmap = new Unmap({ key: "um_live_..." });

const here = await unmap.geocoder.reverse(-114.0719, 51.0447);

Pass longitude first. The answer is still an array. A downtown point usually comes back as an address; a point in a park or on the water comes back as whatever is nearest in the corpus.

There is no cross-border reverse lookup. A coordinate in the United States returns whatever Canadian row is nearest, which is the wrong answer, or an empty array.

The Geocoding API documents the reverse endpoint.
