Geocoding¶
DKAN’s native Datastore offers a geocoder which can add a “lat” and “lon” field to resources that have plain-text address information. This will allow users to provide map coordinates and a map preview for selected resources.
To use the geocoder, click “Manage Datastore” on a resource that has a csv file uploaded to it with address fields.
