Key:material

material=* – describes the main material of a physical feature.

It is most commonly used to describe the material of monuments, memorials, statues, walls, fences, but can be used for any other physical object except those listed below, which use other tags:

• building façade → building:material=*
• roof of a building → roof:material=*
• surface of roads → surface=* for values such as surface=asphalt or surface=mud
  • For surface=paving_stones there is paving_stones:material=* tag
  • For surface=sett/unhewn_cobblestone and other similar you can add detailed material like material=concrete/granite - do not use surface=granite/marble/etc. as it blocks adding standard surface=* denoting their shape
• what is inside, for example a storage tank → content=*.
