Hi WanMil The following links have addr:interpolation http://www.openstreetmap.org/browse/way/38186936 http://www.openstreetmap.org/browse/way/38143561 There is no hurry with this as I realise the current tool generates some interesting if not inexplicable results, at least on mapsourse. I have a feeling that if a road X has been split, say into 2 chunks,a Mapsource search focuses on the last chunk, as if it can't correctly identify the complete road.ie In the same area, you will find Langaton Lane which has been split because half of it is a bus route. If I enter a street number 1 it points to the lowest of the last chunk, not the lowest of the street. Exeter is festooned with addresses number entries making it easier to evaluate the current tool.
