Boundary types
boundary	aboriginal_lands		A boundary representing official reservation boundaries of recognized aboriginal / indigenous / native peoples.

boundary	border_zone		A border zone is an area near the border where special restrictions on movement apply. Usually a permit is required for visiting.
boundary	forest		A delimited forest is a land which is predominantly wooded and which is, for this reason, given defined boundaries. It may cover different tree stands, non-wooded areas, highways… but all the area within the boundaries are considered and managed as a single forest.

boundary	hazard		A designated hazardous area, with a potential source of damage to health, life, property, or any other interest of value.
