There are several ways to tag landcover with existing tags but if we where to define a new tag for grass along the lines of http://wiki.openstreetmap.org/wiki/Proposed_features/landcover I would think it could look something like this:
I like to take up the possibility to use a landcover-key for grasslands and other areas of low vegetation that are not shrubs. I am influenced by the FAO- landcover scheme and in short they suggest that one determines the dominating lifeform (tree/shrub/herbaceous). If the trees are more than sparse it is some kind of forest, if not and there are more than a sparse layer of shrubs it is some kind of shrubland and if not one of those it is herbaceous. (then they use a lot of more attributes to narrow it down) landcover=herbaceous Herbaceous is a bad word as it is rather hard to spell right. My guess is that it is a fancy latin word for herb-like, so maybe I can use landcover=herb or landcover=herbs instead. I relate herbs mostly to flowers and herbal spices and not soo much of grass. Apparently FAO means low growing vegetation that you could walk through, typically a kind of grasland. Herbs are vegetation that isn´t woody (another biology term) Shrubs and heather are defined as woody. Another approach would be to replace herbs with something more common like grass. landcover grass should then cover all herbaceous vegetation. That might be hard for people to reconcile with in special nature where there are mostly non-grass herbs. Another issue is that FAO makes a difference between managed or cultivated vegetated landcover and other "natural or semi-natural" vegetated landcovers. One of the big good things brought forward in the landcover discussion have been the possibility to get rid of landuse=grass, especially for big managed lawns in urban areas. The reason FAO give for separating them is that the finer granularity of the classification follows different schemes depending on if it is managed, cultivated or if it is more like in the nature. Not that there are missing tags to use for herbaceous areas, look at [[vegetation]], there are especially one broad and general tag http://wiki.openstreetmap.org/wiki/Tag:natural%3Dgrassland has a nice definition: "Natural areas where the vegetation is dominated by grasses (Poaceae) and other herbaceous (non-woody) plants. Excludes cultivated areas and wetlands." I would like to have a similar landcover-tag that does not care if it is natural or not and includes what FAO calls managed lands (lawns, parks as opposed to cultivated lands like farms that are harvested) _______________________________________________ Tagging mailing list Tagging@openstreetmap.org http://lists.openstreetmap.org/listinfo/tagging
