HOW TO

Create a locator map to display all extents in a map series in ArcGIS Pro

Last Published: August 27, 2024

Summary

In ArcGIS Pro, a layout can include a map series, highlight specific areas of interest, and feature a locator map. The locator map provides an overview of the extent of each feature within the map series and illustrates the relationship between each page and the broader geographic area.

This article describes the workflow to create a locator map to display the extents of each page in a map series in ArcGIS Pro.

Procedure

  1. In ArcGIS Pro, create a locator map.
    1. In the Catalog pane, duplicate the active map to create a locator map. Right-click the locator map and select Open.
    2. Rename the locator map. In this example, the active map is named Venice Landmarks and the locator map is named Venice Overview.
    3. On the locator map view tab, in the Contents pane, uncheck the check boxes for the feature layers to display only the map.
  2. Create a map series.
    1. Create a layout and insert two map frames; the active map and the locator map views. Refer to ArcGIS Pro: Insert a map frame for further instructions.
    2. In the layout view, create a map series for the active map.
    3. On the ribbon, on the Layout tab, in the Map group, click Activate The Activate icon.. Pan and zoom the map to adjust the extent.

    6. Select the locator map frame and insert an extent indicator. Optionally, change the extent indicator's symbol. In this example, the extent indicator is blue in color.

The image below is an example of a map series with two map frames: the locator map (above) and the active map (below).
