Buffers

Buffers are used to define separation zones that outline permitted land uses. For example, if property developers intend to expand residential areas beyond the designated boundaries, a buffer can be applied to represent the approved width, as well as an additional buffer to illustrate the proposed extension.

Adding a Point Buffer

1. Click the icon under Buffers on the map toolbar, to access the Buffer Wizard.

2. Enter a unique name for the buffer in the input field.

3. Click the map to get the center point where the buffer is located.

4. Add a buffer, by entering a radius (in meters) and a colour.

Click Add Buffer for each buffer, you can add as many as you want.
All buffers will appear in the current buffers list at the bottom of the wizard.

5. Click the Save button to add the new buffer.
