If the selected data frame (main map) is being used for Data Driven Pages, the outline of the current index feature is used as the indicator.Not checking Use simple extent has three possible results: When Use simple extent is checked, the extent indicator shows the geographic bounding box of the selected data frame (main map). Or you can add a leader line and customize its display. You can change the indicator's default red outline symbol to another color or symbol if you want.
There are a number of ways you can customize the extent indicator. Extent indicators also update when the data is rotated or the projection is changed. They automatically update whenever the extent of an associated data frame (main map or locator map) changes. For example, your locator map might show the location of a state (main map extent) within a country (locator map extent).Įxtent indicators are dynamic. A good locator map also contains an indicator, such as a red outline, showing where the extent of the main map fits within this larger extent. This larger extent should be recognizable to the map reader. A locator map shows a larger area, or extent, than the main map. To provide spatial context to the map reader, you might want to create a locator map. Sometimes the area that you show in your map (primary or main map) does not have a commonly recognized outline. This is useful when you are creating overview or locator maps.
