Buffer

This function allows you to create a set of one or more buffers around point, line or polygon features

Dialog box

Dialog box options:

Dialog box

Input polygon map:

Select an input feature map. Open the list box and select the desired input map, or drag a feature map directly from the Catalog into this box. No special input map requirements.

Buffer distance:

The distance of the boundary of the output polygon(s) to the boundary of the input feature(s). This number must be positive for all non-polygon features. For Polygons the number maybe negative or positive. Positive number expands the polygon. Negative distance shrinks the polygon

End Cap style:

The style of the ending of the lines that where buffered. Options are 'Round', 'Square' or 'Butt'

Square creates a rectangular ending at the buffer distance of the end of the line. Butt cuts it directly at the end of the line and Round creates a rounded ending at the buffer distance of the end of the line

Output point map:

Type a name for the output point map that will contain the polygon label points.

Description:

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

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