The original street may have been traced from a different source, or added as the result of a GPS track, but the user can identify which street it is by looking at the line of it because it is overlaid on our map. If the PhotoMap wasn't visible under the trace, I would agree that source=nearmap isn't as valid, but because the map is an essential part of the context that allows the user to confirm which street it is, I'd argue that adding (rather than replacing) source=nearmap reflects what's actually happening; the data is being *partially derived* from the map. And setting source=nearmap for adding housenumber nodes is even more appropriate :) Or would you argue that source isn't the correct tag to track the derivation history of OSM data?

The more fields to fill in, the more complex the interface and the less suitable for general users (i.e., those who are not mappers and don't really care very much about mapping). We might do this (as you suggest, it's a good way to emphasise the "do not copy" rule), but that's still under discussion. > If that's not feasible, I hope you use some other technique to make it very > clear to users that they must not copy street names from a non-free map. We understand this point very well :) Cheers b -- Ben Last Development Manager (HyperWeb) NearMap Pty Ltd
