It is unfortunate that the suggestion to not aim for introducing an
umbrella tag was not taken into account.
The proposal as is lacks clarity of what it actually suggests and how
this new tag delienates against existing tags. It also lacks
comprehensive practical guidance for the mapper how to identify and
delineate features with this tag based on real world on-the-ground
What you essentially attempt to introduce here is a *residual* tag to
turn the open OSM tagging system consisting of tags that positively
identify specific real world features into a closed land cover
classification system modeled after countless such systems (some of
which you cited).
In OSM we generally think that using an open tagging system where the
tags are narrowly defined in what the positively mean in a locally
verifiable fashion is better for representing the global geography in
all its diversity and to document local knowledge of people than a
closed classification system that assigns the class with the lowest
mismatch in a classification developed from a specific culturally
narrow perspective to every point of the earth surface.
Side note: Measuring percentage of ground cover in an arid/semiarid
context is usually not practically verifiable on the ground, in
particular in areas with strong seasonality. Examples:
We definitely do not want such areas to be engrossed in some
generic 'unvegetated or sparsely vegetated area' classification.
