Meta Box Geolocation is an extension of the WordPress Meta Box plugin which interacts with Google Maps Geocoding API and automatically populates location data into your fields such as postcode, state, country.
When developers have to enter the information for a shop or a restaurant, there must have much information like address, state, suburb, post code, latitude, longitude, etc. It is a slow and time-consuming work. Meta Box Geolocation provides a better way to enter these data automatically and properly.
With Meta Box Geolocation, no more complex work with Google Maps API. The only work you should do is just registering your desired fields (address, postal code, country, etc.) as normal fields in Meta Box. Whenever users enter an address, all the information for that location will be pulled from Google Geolocation and filled in other fields automatically.
And due to the google large database, it will be the exactly correct.
