The thing I am tagging is not a dam. It is a series of flood basins, one of which is a "reservoir". They are made by levees that surround the rivers, but in a very complicated way. They eventually return all the water back to the river, shortly after it is captured. I explain that below, if y

So, summing up the ideas expressed so far, in the example case of a stop sign on a two-ways way (not an all-ways stop), we have: 1- highway=stop+direction=forward node on the way to an intersection - Advantages: simple, uses the well-known direction=* tag, easy for routers to interpret - Disadva
