Classic advertising billboard is 4m width * 3 m > height, and is supported on 3 m legs , therefore the total heigth is 6 m. yes, we'll need a tag for height above ground. There is min_height, but it seems to require a building for some strange reason, and more strangely, to redefine "height": https://wiki.openstreetmap.org/wiki/Key:min_height it really is a pity, it is the analogous problem of building:levels which according to the wiki are not indicating the number of building levels but the number of building levels plus some imaginary, non existent building levels. It's really crazy. Cheers, Martin
