The First Responder Geocoder is a web app that can geo-translate / geo-reverse the following types of points:
- Addresses (inc Postcodes)
- Latitude / Longitude
- Grid References – Eastings / Northings
- OS Grid References
The app utilises the following APIs to achieve this.
What 3 Words
What is what3words?
what3words is an easy way to talk about any precise location in the world. It gives every 3m x 3m square a unique combination of three words: a what3words address.///makes.solo.bike is the what3words address for the exact 3m square where you will find a statue of Peter Pan in Hyde Park, London.
A what3words address is more precise than a street address, and many people find three words easier to remember and say than GPS coordinates, grid references or latitude and longitude.
Anyone can use the free what3words app or online map at what3words.com to find, search or share what3words addresses. You can find, search or share a what3words address in over 40 languages to date.
Google Maps API
99% coverage of the world, 1 billion places
Google Maps API is a set of application programming interfaces that lets us talk to its services. It will allow us to build from simple apps to very sophisticated location-based apps across all platforms. Geocoding is a process of converting a street address to geographic coordinates (latitude & longitude).
The Reverse Geocoding is the opposite which coverts geographic coordinates to an actual human-readable address.
