Data Driven Pages gives us the ability to generate a set of output pages by taking a single layout and iterating over a set of map extents. The extents are defined by the features in a layer and are sometimes called tiles, sections, or areas of interest (AOI). The layer that defines the extents is referred to as an index layer. Any feature layer may serve as the index layer. We create and customize new Data Driven Pages using the Setup Data Driven Pages dialog box.
