OpenLR™ - Open, Compact and Royalty-free Dynamic Location Referencing
Welcome to the website of the OpenLR™ project. OpenLR™ is an open source software project launched
by TomTom International B.V. in September 2009. This project provides a royalty-free dynamic location
referencing method which enables reliable data exchange and cross-referencing using digital maps of different
vendors and versions. OpenLR™ will help to enhance existing applications and will generate opportunities
for new services.
Since OpenLR™ is open source everyone is invited to contribute to and to enhance the
exististing solution. This website offers a reference implementation of the OpenLR method and also provides a
complete documentation in terms of software documentation and a technical whitepaper. A detailed presentation on OpenLR™ also addresses both,
technical and business issues.
Additonally we offer an open forum where everyone is invited to discuss topics related location referencing in general
and related to OpenLR™ in particular. You can subscribe for free to our OpenLR™ newsletter if you want to get
the latest news, changes and announcements and you can also report and track issues you experienced with the OpenLR™ software.
A FAQ (frequently asked questions) section shall answer common questions but feel free to contact us directly if
you have further questions or remarks.
