This article describes geocode and traveltime, two commands that use Google Maps to provide spatial information for data. The geocode command allows users to generate latitude and longitude for various types of locations, including addresses. The traveltime command takes latitude and longitude information and finds travel distances between points, as well as the time it would take to travel that distance by either driving, walking, or using public transportation.
