Geocoder Ariadna on ElasticSearch with OpenStreetMap

This is the open-source geocoder built on top of ElasticSearch for fast geocoding and providing better search for CIS countries.

You could find more information about Ariadna designing in our blog.

What's a geocoding?

Geocoding is the process of transforming input text, such as an address, or a name of a place—to a location on the earth's surface.

What can the Ariadne geocoder search for?

• Street + housenumber;
• Road intersections;
• Points of interest;
• Microdictricts;
• Addresses in microdistricts;
• Nearest villages and towns;
• Search with auto replace from dictionary;
• Reverse geocoding.

What's reverse geocoding?

Reverse geocoding is the opposite, it transforms your current geographic location in to a list of places nearby.
