OK, I agree. Clause 4.7 (reverse engineering) though prevents people from recreating the database from a produced work. So if they're just pinning the locations on the paper map, that's fine. But if they are reading off the lat/lon from the margins (or from the pixel coordinates on screen) and recording that, then it would depend entirely on the interpretation of whether what's been done is a "Substantial part" or not. Presumably not in this case, but when it becomes Substantial is not well defined and would probably need a test case. Some guidance to people would probably be helpful (e.g. for the sake of argument, just quoting grid references with reference to a map image is not infringing, even in large quantities, but tracing over the map image is).
