Can I add a buffer around my Surfer object (or a setback around a well)?

Yes, you can create buffers around objects at specific distances. This could be a buffer around a road, stream or a region (e.g. a setback) around a well. You can also create range rings at specific point locations.


Buffer can be created around objects in a base layer. You can create buffers around points, polylines and polygons. The distance units used to create the buffer are the same units that the map is in.

To create a buffer:

  1. Right click over the Base layer in the Contents window that contains the object you wish to create the buffer around and click Edit Group. The base layer must be in edit mode.
  2. Select the object(s) you wish to create the buffer around.
  3. Click Features | New Features | Buffer.
  4. In the Buffer dialog:
    1. Enter the Number of buffers to create. If you choose more than one, they'll be concentric with equal distances between them.
    2. Enter the Buffer distance in the same units that the map is in.
    3. Choose whether or not to combine overlapping buffer polygons. You might want to combine them if you select multiple roads or rivers, so that you get one polygon around them all instead of individual overlapping polygons.
    4. Click OK.
  5. Right click over the Base layer in the Contents window and click Stop Editing Group. Each buffer polygon is created as a separate polygon, as seen in the Contents window. You can adjust the properties of each polygon individually to change the line or fill colors. To adjust the buffer distance, recreate the buffer.

Surfer buffer rings

Create buffer areas around objects at specified distances, such as concentric areas around well points, or a combined polygon around streams.

Range Ring

A range ring creates concentric circles of a specific radius around a selected point location. To create a range ring in a map:

  1. Select the existing map.
  2. Click Home | Add to Map | Layer | Empty Base.
  3. Right click over the new Base layer in the Contents window and click Edit Group.
  4. Click Home | Insert | Range Ring and click on the map at the center location for the circle.
  5. Right click over the Base layer again and click Stop Editing Group.
  6. Select the range ring and adjust any of the settings (e.g. number of rings, radius, color, symbol and line properties, etc) in the Properties window. The radius value is in map units, so if your map is in UTM coordinates (meters), then the radius value is also in meters.

Surfer range rings

Create range rings at specific point locations. Adjust the number of rings, symbol properties, line and fill properties, or change the shape from a circle to a square.
