Setting up a fixed buffer
The buffer represents the space around a particular feature in spatial or linear units. You choose to configure your own fixed buffer using the Fixed Buffer option.

This is the value that will be associated with the buffer for each AOI feature.
Click the Map Units or Page Units option.
If you choose Map Units, the buffer is calculated based on map units within the data frame. For example, a 100-kilometer distance can be maintained in map units between the edge of your AOI and the edge of the data frame.
If you choose Page Units, the units create a buffer around your area of interest (AOI) in page units. For example, a page distance of 1 centimeter between the edge of your AOI and the edge of the data frame can be maintained.
- Click the drop-down arrow for the units you have chosen and choose the unit of measurement you want to use in association with the distance designated in the Distance text box.
The Scale and Extent dialog box appears.
