Code List: SurfaceTypeValue

Value	Description
Made Sealed	A constructed surface, commonly mineral based, that consists of a solid material that is bonded (i.e. is not loose) such as asphalt or concrete.
Made Unknown	A constructed surface, commonly mineral based, that may be bonded or loose. This value is used where the revision method employed does not allow it to be differentiated into ‘Made Sealed’ or ‘Made Unsealed’.
Made Unsealed	A constructed surface, commonly mineral based, that consists of an unbonded surface (i.e. the material is loose) such as gravel (including self-binding gravel), cinder or hoggin. Also used to describe surfaces that are bonded but have been employed as a mesh/grid or similar form; to allow vegetation to grow and water to drain through the surface.
Unmade	A surface that has not been constructed but has evolved through use by pedestrians, cyclists, horses being ridden or motorised vehicles and where the use has removed or minimised the natural vegetation and fully or partly exposed the underlying mineral surface and/or mud.
