The OpenLR data package comprises interfaces for OpenLR location references and also interfaces for encoding and decoding the internal data into a defined physical format and the other way round.

The binary package consists of classes for reading and writing binary location reference data. The OpenLR encoder uses this package to create a binary representation of a location reference.

The decoder package holds the reference implementation for the OpenLR decoder. It takes a (map-agnostic) location reference as input and finds back a corresponding (map-dependent) location reference.

The encoder package holds the reference implementation for the OpenLR encoder. It takes a (map-dependent) location as input and generates a corresponding (map-agnostic) location reference.

This library provides a command line interface for use with the OpenLR reference implementation and the Tele Atlas OpenLR Access Layer for SQLite.
