Actually these two points well illustrate an important difference - something is missing because someone misses it - this is a subjective criterion. Much of the discussion in this thread revolves around the question of differences between locals missing data and non-locals doing so and what conflicts might arise from this difference. So showing prominently that something is missing from a certain subjective perspective is always touchy, especially if it is the perspective of someone with a broader agenda like a foreign aid organization or a company. The first point on the other hand is probably fairly undisputedly a good idea, i.e. indicating quality issues from an objective perspective. We already have a lot of tools in that area of course, address lists for example that are used to indicate where addresses are missing. But there is a real lot of potential there, like for example rather than importing external data using it to find and indicate differences to what is in OSM. There is much free data out there that could be used to very specifically indicate inaccuracies and errors in OSM data but not a lot of ressources are used at the moment to make use of this. -- Christoph Hormann http://www.imagico.de/ _______________________________________________ talk mailing list talk@openstreetmap.org https://lists.openstreetmap.org/listinfo/talk
