Concentric Ring Buffer Tool - MapInfo_Pro - 2023

This tool creates concentric ring buffers around one or more map objects. The tool also computes aggregated values for underlying data that occur within each ring. Therefore, it can be used to count how many customers occur within each ring and their total sales.

To create a concentric ring buffer:

1. Select the object(s) you want to place buffers around in the Map window.
2. On the Tools menu, choose Concentric Ring Buffers and click Create Ring Buffers. The Concentric Ring Buffers dialog box displays.
3. To add a ring, specify the radius in the Radius field and click Add Ring. Continue this until you have added all of the rings you want from the smallest to largest.
4. Select the units of each radius in the Units drop-down list.
5. To set the smoothness of the ring buffer, type a number between 3 and 100 in the Smoothness field. The larger the number, the smoother and less jagged the curves of the ring.
6. Type the table name and select the path in which you want to store this buffer information. MapInfo Pro stores the concentric ring buffer information into this table including the columns containing the ring number, radius value, radius units, area, and area units for each ring.
7. When you have finished the buffer settings, click OK.

Use the Modify Ring and Delete Ring buttons to change the ring settings, or click Clear All to start all over and create new concentric rings. To change the style of a buffer ring, select it in the Buffer Radii list, and use the style buttons to change the fill pattern and line style for the buffer. You can also collect data within each buffer ring using the Calculate Ring Statistics button.
