Re: [Tagging] landuse=grass = natural=grass
2014-09-18 11:44 GMT+02:00 Pieren pier...@gmail.com: I think the consensus is to stay as simple as possible and use only one tag to say that there is grass on this piece of land. I think the consensus is to describe any property you like in OSM. Using only one tag to summarize a lot of aspects is hardly ever a good idea, because it limits the way to use the data and makes contributors life more complicated and not easier (because they have to weight a lot of aspects instead of directly tagging what they see). cheers, Martin ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

I use landuse=grass in urban areas (Grünstreifen am Straßenrand), for grass areas that are not a garden but there usage is just to have a (nicht-versiegelte Fläche; whatever that means in English) green spot there. Another usage: eine Böschung (whatever that means in English? batter?). Those are man-made, not natural. And landuse makes no sense there, for instance a 1m x 1m landuse of grass around a tree. /al ceterum censeo landusem esse delendam ;) (for all the neo-Romans here ;) ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
Re: [Tagging] landuse=grass = natural=grass
Hi! 2014-09-17 23:44 GMT+02:00 Daniel Koć daniel@koć.pl: We (in Polish forum) think, that changing landuse=grass into natural=grass would make better tagging scheme, since grass is seldom a landuse (like the tree is natural=tree, not the amenity or something else). How do you find this idea? Not good. Contrary to other people I think that the readability of tags is most important, otherwise we could simply use tags like ptn=pnx or road=flying_saucer and define that those tags mean grass. Both could be processed perfectly fine but obviously doesn't make any sense at all. A while ago I wrote down some thoughts about a cleanup of landuse/natural/surface with the intention of clearly separating those tags and make it more easy to understand their meaning. I have to admit that I lost interest in this area so my writing just sits there and waits for someone to adopt it: http://wiki.openstreetmap.org/wiki/User:Imagic/landcover . The first section When to use ... would be the most important in your case. Therefore I would recommend landcover=grass in your case. If this area is also used to e.g. produce hay I would also use landuse=meadow. Best regards, Martin ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Most of the contributors don't care if the magic keyword is landuse or natural or surface or landcover for that and most of them wouldn't agree to draw different polygons or use several key to make such small subtleties.

Land is never covered by trees alone. Trees are usually accompanied by bushes, grass and other herbs, moss, algues, insects, etc. Alternatively, all of these (including trees) could be considered part of the land. In this case, landcover can only be hydrosphere and/or atmosphere. So what's your definition of land and landcover? -- Friedrich K.

How do you find this idea? Fine, but landuse=grass, landuse=meadow, natural=grassland and surface=grass are all in use. No need for just another synonymous tag. Consider tags as codes as in a programming language. It's fine if they are self-explanatory, but more important is a clear definition and consistent usage. 1.
