land:offsetDistance

Represents a linear offset distance. When associated with horizontal (planametric) road or coordinate geometry, the offset is a 2D distance measured perpendicular to the road centerline or coordinate geometry used as the origin. When used in cross sections of long section (profile) the offset is a 2d linear measurement from the origin of the cross section or long section. In all cases a positive value indicates an offset to the RIGHT of the origin and negative values indicate and offset to the LEFT of the origin. The value is in decimal form expressed in length units.
