HI all
I just stubeled uppon an annoucement [1] that TomTom (make of GPS navigation devices) will launch an OSS project for location aware services/data, called OpenLR [2].
They call it a "universal location referencing technology" and call it "map-agnostic". Not quite sure what's behind it - a collection of data layer? an protocol for supplying and polling such data?
I didn't dig deep, just though it might interest you...
