The reference direction codes come from the standard FHWA rosette: 1=N, 2=NE (not used here), 3=E, 5=S, 7=W

ReferencePost (Mile Marker) is the number on the green sign. There is a RefPost_Tenths field available in the source data (oracle database, shared schema) for the enhanced centerline posts found on the interstates, but it is not currently available in the khub data.

Attributes in KHub are: [ReferencePost],[ReferenceDirection], ,[MeasuredLatitude], ,[MeasuredLongitude], ,[MeasuredAltitude]

The measured Lat,Long attributes would be helpful to create point locations based on the spatial coordinates (Lat, Long) rather than county LRS logmile

The attribute ReferenceDirection uses the domain dReferenceDirection

HISTORY

From CANSYS Metadata Master Report:

STRP - (State Reference Post)

State reference posts are the green mile marker signs along the roadway. Note that the number reflected on the mile marker will not always match the route milepost of the location of the sign. When a roadway is changed the sign doesnt always gets moved in the field.
