Completely agree. I was thinking along similar lines given that I want the new data to be useful, instead of making a royal mess of what we've already got. I would be extra sweet to be able to do a a comparison between the OSM layer and data layer so that we can highlight new/different stuff (eg in 3 months we get a new data set and want to easily spot the new stuff to import).

And not doing it that way. I'd personally prefer if if this kind of data wasn't even to be merged straight away. If it were made available in a format JOSM can overlay, actual humans could then go over it in the same way we currently do with Yahoo! imagery. Benefits: * Crowdsource the import task. * Humans have a better idea as to how the data should be portrayed in OSM. * In already populated areas, humans are better at working out what should be merged. * It's better to build the map from the bottom up, rather than the top down. (By this I mean, it's better to import the data slowly and surely, rather than using import tools and having to go through and fix it all.) Drawbacks: * Takes time, not that we don't have it. * Takes more effort, but with a greater result. Just a thought. :) Ash.
