Pole, Tree, or Sign

Poletreesign is one of the General Hazard Type s  in RSAP describing a type of  Roadside Hazard .   The station and Offset of, for example, a single tree may be specified.   RSAPv3 will then ask for the diameter of the tree.   The same procedure is used for other similar objects like poles, signs and luminaire supports.   The figure below provides an example.   The photo is taken looking in the primary direction of travel, so the direction of the Offset is Right.   The distance of Offset is measured from the Baseline (e.g, the Baseline is the centerline of an undivided road) to the center of the hazard.
