Segment direction histogram

Dialog box

The Segment direction histogram operation calculates directions and lengths within segments, i.e. between all stored coordinates of the segments. The output is a table with directions from 0 to 179° and the length and number of the segment parts in that direction.

Dialog box options:

Input segment map:

Select an input segment map. Open the list box and select the desired input map, or drag a segment map directly from the Catalog into this box.

Output table:

Type a name for the output table, i.e. the output histogram, that will contain the direction, length and frequency of the segments in the input map.

Description:

Optionally, type a description for the output histogram. The description will appear in the status bar of the Main window when moving the mouse pointer over the histogram in a Catalog, and in the title bar of a histogram window when the output histogram is displayed. If no description is supplied, the output histogram will use its own definition as description.

When you click the Show button, the dependent output table (the histogram) will be defined, calculated and shown. When you click the Define button, the dependent output table will only be defined; if necessary, the histogram will be calculated later, for instance when the histogram is opened to be displayed.
