As an extremely large number of such messages have seen the light of day since 2009 and each tweet is marked with a dot, not only the maps but also cities, roads and differences within urban centers can be identified. Even individual busy sea routes become visible. If there are many points at the same location, the color changes. Incidentally, all maps can be displayed on Flickr and can be enlarged to the original size by right-clicking. (hae)
