Underground Conduit Template

 

Positional Accuracy

            Definite - Conditions permit the feature to be confidently positioned. Horizontal data are  

confidently positioned within 0.02", at map scale, of the true ground position. Vertical data are

confidently positioned within one-half contour interval of the true ground position

 

          Indefinite - Conditions prevent the feature from being confidently positioned. Horizontal data

cannot be confidently positioned within 0.02", at map scale, of the true ground position. Vertical

data cannot be confidently positioned within one-half contour interval of the true ground position

 

Delineation

The limit of UNDERGROUND CONDUIT is the extent of the known underground channels.
