Rchk Road check. This record defines a point on a road by station and offset, not coordinates. It also contains fields showing the difference between the station and offset set out and the design point's station and offset.
RED Reduced record. These fields define a point-to-point vector. Source point name, target point name, azimuth, horizontal distance, vertical distance, and a descriptive code are listed. An observation record in reduced (RED) view looks the same as a RED record.
Rd This record marks the start of a road definition. It contains the name of the road.
