probably no. Landuse is describing the actual usage of the land. If there is only grass, it cannot be considered industrial, regardless of who owns the land. > Partly this gets back to the debate about whether a map is an abstract > representation, or whether it's essentially a 2D bitmap of the real > world. We can't do different then use abstraction. What you are thinking about is resolution IMHO. Every generalisation should be aware of the scale the map will be printed. As we are trying to create an universal database (i.e. there is no such thing as a fixed scale in OSM, although there is some scale limits like the precision in which we store the coordinates), the finer the data is structured, the more possible maps could be made out of it. cheers, Martin _______________________________________________ talk mailing list [email protected] http://lists.openstreetmap.org/listinfo/talk
