* B = Breakline/Line Feature included in the DTM (any Code can be a Line Feature using Linking Codes but only those w/ a B will be included in the DTM)

G = graphic element only; will not be included in the DTM

To map multiple features of the same type, add an 

alpha numeric character to the end of the code. 

Example: If mapping more that one edge of asphalt, 

identify each with a different alpha numeric suffix,

 3021 or 302L = Left edge of asphalt, 

302 or 302R = Right edge of asphalt and so on. 

 

Use # symbol after field code before Description, if a 

description is needed.

Examples:

 BL 201R#Barbed Wire

232#Curve Ahead 

Linking Codes: At beginning

BL = Begin Continous Features

EL = End continous feature

CL = Close on a continous feature on the beginning 

point

PC = Start of Curve

PT = End of Curve 

Include a space between linking code and code

There can be numerous measurements between the PC 

and PT.
