You may wish to have different backgrounds or combination of backgrounds set behind the layers you have turned on in the map. A Basemaps tool is available to accomplish this task.

Below is a video of how to use the Basemaps. There is also a step-by-step guide located below the video Here.

How to Use the Basemaps Tool

  • Open the Basemaps tool and click a Basemap thumbnail to set it as the background of the map. If the year of aerials you wish to see is prior to 2011, please click the link at the bottom of the Basemaps tool to go to the Historical Aerial Photography site.

  • You can create a hybrid background of 2 Basemaps by clicking the plus sign that appears when hovering over a basemap icon.

  • When 2 Basemaps are selected a slider becomes visible in the top section of the Basemaps tool that will let you determine which background will be more visible.

  • If you wish to remove one of the Basemaps from the background of the map, hover over it and click the X to remove it.
