Delineation

The limit of WATERFALL is the extent of the vertical or nearly vertical descent, and the

SHORELINES.

 

If WATERFALL is on a 1-dimensional STREAM/RIVER,

Then WATERFALL is represented as a 0-dimensional basic feature object.

 

If WATERFALL is on a 2-dimensional STREAM/RIVER,

Then WATERFALL is represented as a 1-dimensional basic feature object.

 

Data Extraction

Capture Conditions

 

If WATERFALL is named,

Or

If WATERFALL is on a perennial STREAM/RIVER and has a vertical drop ≥ 10 ft, and

extends from SHORELINE to SHORELINE,

Or

If WATERFALL is within an area of closely spaced waterfalls and is necessary to

accurately represent the pattern of waterfalls (see Source Interpretation Guidelines to

determine how to accurately represent the pattern), then capture.

 

Source Interpretation Guidelines

 

All

If WATERFALL is within an area of closely spaced waterfalls,

Then first capture upstream WATERFALL, and then capture as many others as

can be shown in correct position. The symbols must not overlap.

 

Graphic

 

Capture all.

 

Names that contain the word "Falls" may indicate the feature RAPIDS. Careful

identification of the symbol will be required to accurately determine whether the

feature should be captured as WATERFALL or RAPIDS.

 

If WATERFALL is on a single-line STREAM/RIVER,

Then capture at intersection of tick and STREAM/RIVER.

 

If WATERFALL is shown by a tick on a double-line STREAM/RIVER,

Then capture by connecting the intersection of tick and SHORELINES.

 

If WATERFALL is shown by hachures on a double-line STREAM/RIVER,

Then capture by connecting the upstream limit of the hachures and

SHORELINES.

 

An elevation at the top and/or bottom of WATERFALL is captured as SPOT

ELEVATION.
