reverse-geocoding

Flask WSGI web application for geocoding

Meaning

"Reverse geocoding is the process of back (reverse) coding of a point location (latitude, longitude) to a readable address or place name." Wikipedia

"Nominatim (from the Latin, 'by name') is a tool to search OSM data by name and address (geocoding) and to generate synthetic addresses of OSM points (reverse geocoding)." OpenStreetMap Wiki

#1 Implementation

The application listens on /api/v1/reverse and takes lat, lng and app_name as HTTP GET arguments. It then returns reverse geolocation for the given latitude and longitude point. Application name is used as an identifier for OpenStreetMap API.

Setup

Please refer to Flask documentation

Example

Query:

$ curl "http://localhost:5000/api/v1/reverse?lat=52.509669&lng=13.376294&app_name=my_application"

Will return:
