Grid Buffering

80

Vertical Mapper 3.7

If you choose the Use Maximum Distance setting, you must specify the maximum distance between
locations where a circular buffer will appear. If the maximum distance setting is too great, as shown
in the next figure, there will not be enough circular buffers to cover the length of the line.

This graph shows the result when the Use Maximum Distance option is chosen and
the distance setting is too big.

By reducing the distance setting, the buffers will cover the whole line. This is illustrated in the next
figure. Generally, the distance setting should be at least half of the buffer distance. For example, if
you create buffers at 1 000 m, the maximum distance setting should be at least 500 m.

This graph shows that the buffer covers the whole line when the maximum distance is
reduced properly.

Creating a Grid using the Grid Buffer Tool

1. From the Vertical Mapper menu, choose the Create Grid > Grid Buffer command.
2. From the Source Table list, choose a table for processing.
3. In the Distance Between Points section, choose either the Use Nodes Only option or the Use

Maximum Distance option and define the distance value between points in the Distance box.
The maximum distance between points should always be equal to or less than the search radius.

4. Click the Next button.
5. Define Cell Size and Buffer Distance settings.
