Imported data is rarely touched, even when the quality is low > (ie TIGER). I ran an experiment to see if a local mapper would be willing to re-position a node that can't be seen on an air photo. We already know that armchair mappers are willing to make similar corrections. Here's the experiment: http://www.openstreetmap.org/note/313414 The node was properly moved to the opposite side of the street, by user dchiles. ----------------------- As a crowd sourced map, it should be within reach to find 500 local mappers to validate 500 locations. No commercial effort could match this (the cost of airfare would be prohibitive). In fact it could be seen as a core strength of OSM: the ability to seek local volunteers scattered across the globe. ----------------------- I see a high quality and extensively vetted data set here, with a chance for engagement by local on the ground mappers to correct what are fairly modest imagery/base layer offset issues. Beyond that, this import has already engaged several bike communities, bringing new mappers to OSM specifically in order to map bike repair stations. This is not low quality data: it's high engagement data.
