  "_type": "geopoint",
  "lat": 58.63169011423141,
  "lng": 9.089101352587932,
  "alt": 13.37

While the geopoint type is available in Sanity by default, you will probably want to install a plugin that provides a more visual way to input the coordinates. For instance, you could use the @sanity/google-maps-input plugin:

cd my-project
sanity install @sanity/google-maps-input

Then configure ./config/@sanity/google-maps-input.json with your Google maps API key:

  "apiKey": "google-api-key",
  "defaultZoom": 11,
  "defaultLocation": {
    "lat": 58.63169011423141,
    "lng": 9.089101352587932

Make sure the key has access to all of the following APIs:

  • Google Maps JavaScript API
  • Google Places API Web Service
  • Google Static Maps API

You can create such keys and grant API access in the Google Developer Console.
