WPGMappity is a WordPress plugin that allows you to easily insert Google Maps into your posts.
Google Maps is a web mapping service application and technology provided by Google, free (for non-commercial use), that powers many map-based services, including the Google Maps website, Google Ride Finder, Google Transit and maps embedded on third-party websites via the Google Maps API. It offers street maps, a route planner for traveling by foot, car, or public transport and an urban business locator for numerous countries around the world. Google Maps satellite images are not in real time; they are several months or years old
