==== Zoom Level Applied: 0~19 ====
Landcover polygons representing the physical material at the surface of the earth and the use of the land by humans. It corvers the "land use (https://wiki.openstreetmap.org/wiki/Key:landuse\" and "landcover (https://wiki.openstreetmap.org/wiki/Proposed_features/landcover\" in OpenStreetMap. The 'ice' is from [[http://www.naturalearthdata.com/http//www.naturalearthdata.com/download/10m/physical/ne_10m_glaciated_areas.zip|Natural Earth]].The polygons are sorted by the area of their geometries to make sure we don't show small polygons at some zoom levels. At lower zoom levels, "class" column is used for styling the landuse layer. At higher zoom levels, "subclass" can be used for more details.

===== Columns =====
==== geometry field ====
''geometry'' type : polygon

==== name field ====
^Field   ^Description^
|''name''   |The name (or names) used locally for the place.|
|''name_en''|English (if available, otherwise same as name)|
|''name_zh''|Chinese (if available, otherwise same as name)|
|''name_ar''|Arabic (if available, otherwise same as name)|
|''name_de''|German name ''name_de'' if available, otherwise ''name'' or ''name_en''.|

==== class & subclass ====
We use ''class'' to assign natural colors for landcover and the ''subclass'' is more precise landcover, eg: vineyard.
