You can use Refine to translate street addresses to lat/lng coordinates to plot data on maps. While there is no native geocoding command in Refine, you can still accomplish this task calling HTTP-based geocoding services using the command Add Column by Fetching URLs and then parsing the returned HTTP responses to extract the lat/lng coordinates.
