Source Interpretation Guidelines

 

All

 

If WALL is not associated with a hydrographic feature,

Then capture in the Built-Up theme.

 

If the edge of LOCK CHAMBER separates water from land,

Then do not capture WALL. See NONEARTHEN SHORE or SHORELINE.

 

If DAM/WEIR, NONEARTHEN SHORE, PIER/BREAKWATER/JETTY,

SHORELINE, or SPILLWAY is captured,

Then do not capture WALL.

 

If WALL meets capture conditions, and coincides 2-dimensional

CANAL/DITCH, hen capture both WALL and CANAL/DITCH.
