Name of the station along a centerline survey. This mustbe a numeric value, with a unit of measure (eg. ft) specified in theuom attribute. Systems that store station values as a string thatinclude a plus sign (+) need to strip out the + and specify the uomfor encoding to DIGGS.
A reference point along a route to indicate eitherdistance travelled or the remaining distance to a destination. Suchreferences are also used by maintenance engineers and emergencyservices to direct them to specific points where their presence isrequired. This term is sometimes used to denote a location on a roadeven if no physical sign is present. This is a numerical value a maydiffer from a station id used for specific routesurveys.
Distance measured perpendicular from the station. UnlessoffsetDirection is specified, positive values imply an offset to theright when facing in the direction of increasing station value.Negative values imply an offset to the left.
Direction of the offset measured along the centerlinesurvey. Allowable values are left and right (when facing in thedirection of increasing station value.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
