Hi Fernando, What I'm afraid of is how a new quality-scale should be used by arbitrary mappers around the world. Let's assume the scale is from 1 to 5 (like tracktype is now).
For a city boy in the US who never left it's city the gravelled highway malenki posted in this thread would be a bad road, probably only worse with a few small holes in it. On the other hand only a perfectly paved asphalt or beton street, smooth and flat would be a great road. For someone living in Tanzania, Africa, who has been once in his live in a bigger city, there may be something like asphalt somewhere on the world, but a well compacted dirt road where you can travel by bike and non 4x4 cars is a great road, connecting states and provinces. How should a single scale be documented and described that you get comparable values into it, especially if you mix different atomic properties to one? Travelling a way by bike is easy even if it's smooth only on the sides while there's much higher grass in the middle. Travelling it with a sports car might be impossible, for a 4x4 car it might depend on the height of it's bottom. So what's the purpose of a single "quality" scale, if quality cannot be determined for any mode of transportation for any street? Of course a single tag simplifies the handling by software and renderers - but I fear, that's on cost of quality and information, if there's no really good property to check on the ground before choosing the appropriate tag value. regards Peter Am 03.01.2014 20:42, schrieb Fernando Trebien: > I don't think that unifying them all into a single tag is a bad idea. > It would be easier while editing the map (only 1 choice to make, > instead of 5), easier to describe to users (instead of 5 different > tags), to consume in applications (such as the renderer, but also in > routers), and it would also use less database space.
