Plateau parameter

... controls the truncation of the crests of the hills. This data manipulation af-

fects the watershed segmentation on the hills. The data for the 3D analysis is

not affected. The parameter range is from 0.0 to 1.0. The default setting is 1,

which is also used in the instrument firmware.

If plateau parameter = 1, no truncation will be done. If plateau parameter = 0,

the crests of the hills will be flattened down to their mean height. The images

underneath show the truncated topography as red line and the segmentation

borders as green lines, illustrated in abstracted form.

Examples:

The following images show the truncated topography as red line and the seg-

mentation borders as green lines, illustrated in abstracted form.

Plateau = 1.0

Plateau = 0.3

Over Segmentation

Good Segmentation

Hill size threshold

... defines the height of the hill intersection for the hill size calculation. The

range is from -1.0 to +1.0. The default setting is 0, which is also used in

the instrument firmware.

Hill size threshold = 0 means that the mean height of the topography is used as

threshold. A value of -1.0 means that the lowest point is used as threshold. This

selects all data as hills. A value of +1.0 generates the opposite output. The rel-

ative threshold parameter ensures the comparability between different

samples.

Examples:

Hill sections are indicated as red areas. The green lines are the watershed seg-

mentation result. The abstracted illustrations above show the intersection

marked as red line and the segmentation borders as green lines.
