>Osmose QA tool do this job. Perhaps I am not aware of everything that Osmose can do, but my basic understanding is that it provides an in browser view of errors already in OSM. What I was trying to propose in (1) and (2) was a really slick, really simple tool that allows the user to load in two datasets (e.g. original and updated file from a government department, or a government file and an OSM extract) and it shows you the big differences in a really simple intuitive way.
For (3) I am proposing a mobile friendly way of getting people out on the ground to verify data provided by a government and load it in to OSM (either there and then via mobile, or back at home on their computer). Happy to do some mock-ups if you like, but can't help much with (3). Longer term I *might* be able to tackle 1 and 2 but it would take me ages to get to grips with it all. Regards, Rob
