Create a mask
The Masking tool lets you focus on a specific map area by removing data from all the surrounding areas. Data will be shown only inside the masked area, the rest will be grayed out.
- In the top right corner of the application, click the menu button , and select Mask Map Data.
- In the Masking tool panel, select the data layer you wish to use to create your mask.
- You may also choose to include nested layers. These will show up as we zoom into the map. If none of the nested geographies are checked, you will only see the geographies you selected.
- In the upper right corner of the map, click the selection tool you want to use and select the areas of interest.
- Click Done.
There are five selection tools available: point selection, rectangle selection, circle selection, polygon selection, and line selection tool. Learn more about using our selection toolbox.
