Using spatial references

This tutorial demonstrates how the API uses a spatial reference.


The /geocode endpoint has an optional at parameter which is usually used to set the current location for location-based search. In this case, the city name normally should be omitted from the query.

For example, a free-form text query for address 32 Tremont st, with at position in downtown Boston and the maximum number of results limited to one is formulated with the following:


The following parameters are used:

  • q - Enter a free-text query.
  • at - Specify the center of the search context expressed as coordinates.
  • limit - Maximum number of results to be returned.
  • apiKey - Your API key.


This request uses API key authentication. For more information about authentication options on the HERE platform, see the Identity & Access Management Guide.

The response to the above request contains a single result in downtown Boston and looks like the following:

  "items": [
      "title": "32 Tremont St, Boston, MA 02108-3201, United States",
      "id": "here:af:streetsection:bTM9lA13maMMGHDXOCPTRA:CgcIBCC225AkEAEaAjMyKGQ",
      "resultType": "houseNumber",
      "houseNumberType": "PA",
      "address": {
        "label": "32 Tremont St, Boston, MA 02108-3201, United States",
        "countryCode": "USA",
        "countryName": "United States",
        "stateCode": "MA",
        "state": "Massachusetts",
        "county": "Suffolk",
        "city": "Boston",
        "district": "Downtown Boston",
        "street": "Tremont St",
        "postalCode": "02108-3201",
        "houseNumber": "32"
      "position": {
        "lat": 42.35852,
        "lng": -71.05977
      "access": [
          "lat": 42.3586,
          "lng": -71.06
      "distance": 280,
      "mapView": {
        "west": -71.06099,
        "south": 42.35762,
        "east": -71.05855,
        "north": 42.35942
      "scoring": {
        "queryScore": 1,
        "fieldScore": {
          "streets": [
          "houseNumber": 1

The response for each item in this case contains the field distance, which is the distance in meters from the at position to this result.
