barefoot - Java library for integrating the map into software and services with state-of-the-art online and offline map matching that can be used stand-alone and in the cloud
An open source Java library for online and offline map matching with OpenStreetMap. Together with its extensive set of geometric and spatial functions, an in-memory map data structure and basic machine learning functions, it is a versatile basis for scalable location-based services and spatio-temporal data analysis on the map. It is designed for use in parallel and distributed systems and, hence, includes a stand-alone map matching server and can be used in distributed systems for map matching services in the cloud. Barefoot consists of a software library and a (Docker-based) map server that provides access to street map data from OpenStreetMap and is flexible to be used in distributed cloud infrastructures as map data server or side-by-side with Barefoot's stand-alone servers for offline (matcher server) and online map matching (tracker server), or other applications built with Barefoot library. Access to map data is provided with a fast and flexible in-memory map data structure. Together with GeographicLib  and ESRI's geometry API , it provides an extensive set of geographic and geometric operations for spatial data analysis on the map.
