The key bond=* can be used to nano map the bond of a brick wall. This can be interesting for historical research or 3D rendering of the building/ wall.
How to map
Important note: Do not analyse the bricks between windows, as the brick layer mostly tried to fill the space as best they could; focus on the areas above and below windows or gable ends instead.
Add building:material=brick or building:facade:material=* to a building or wall=brick to a free standing wall.
Add the key bond=* and one of the following values (list might not be complete, because these depend on the regional tradition of brick layers). It is possible to add several bonds to a building, separated by semicolon.
