A map series is a collection of maps built from a single layout. A spatial series is created by iterating through each feature in a layer specifically designated as an index layer. The map frame shows a different map extent based on the feature from the index layer, and the map series can be ordered alphabetically or by attribute data. In ArcMap Desktop, this process was called building a map book with data driven pages. This task sheet will utilize the Map Series tool to create a spatial map series showing incorporated cities, roads, and waterbodies for each county in Iowa and uses concepts covered in GISTP 0015 - ArcGIS Pro: Creating a Layout.
