I recall coming across some OSM initiative that was proposing to put US address ranges in the data using TIGER (I think). However, I have seen no such ranges in any of the data I have looked at so far. I am wondering if anyone has noticed this kind of information or can point me in the direction of concrete descriptions of its existence (or lack thereof). If it does not exist, is there a method for extracting address ranges from what is given in nodes and ways? I know the data can be very spotty, but assuming a perfect world of open source data editing, if a way is comprised of nodes that each have an address, could one extrapolate To-From address ranges for the left and right side of the line?
