[Tagging] Feature Proposal - RFC - landuse bush

[Vincent van Duijnhoven]

I think landcover=* should not be used at all as an alternative for for example landuse=grass or landuse=bush|shrubs or natural tags. 

I see it in this way. You have tags like natural=*, landuse=* or leisure=garden | park. These are used to tag the use or design (either an_made or natural) of certain features on a piece of earth. That is imo also what carto is trying to render, more the use, design or functionality of a certain piece of land. Every piece of earth has a certain use or feature be it for example landuse=residential, natural=water or natural=scrub. Landcover on the other hand is more a general describing how a piece of land is covered ( e.g. with forest (decidious/ needleleaved), grass(land) or urban). This should therefore not be used on carto to render an area. There are tags like landuse=* and natural=* for. This is a landcover map [1] and imo it should not be confused with what carto and other OSM maps like cycleOSM are displaying. imo, it is perfectly valid to add a landcover tag as a secondary tag to describe the COVER of a piece of land which can then be used to create a separate landcover map of OSM but that should not be on Carto.
