Hi Eugene, > I have a question, how does the tool determine whether a set of ways is > a "floating island" or not?
The motto of this check is "you can go everywhere from everywhere". There is a set of starting points (highways in the center of big cities that are well connected to many other streets) I picked randomly. The check finds ways that are connected to these ways and thus finds a (bigger) set of ways. This procedure is repeated until no more ways are found. Any way that was not found is a floating island. There are 30 starting points all over the world, one of them in Manila. Please note that the check will follow any highway and ferries are included, so it _should_ find islands as long as there's a ferry connected to a highway on the island. This check works best with a dense network of highways that is almost completely mapped, as we have in Europe. But anyway: First thing to try is add some more starting points. Just give me a location and the map will look cleaner after the next update!
