Create a mask
The Masking tool allows you to 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 Change data menu, click the menu button , and select Mask map data.
- In the Masking tool panel, select the geography level you wish to use to create your mask.
- You may also choose to include sub-geographies. These will show up as we zoom into the map. If none of the sub-geographies are checked, you will only see the geographies you selected.
- In the popup next to the masking tool panel, click the selection tool you want to use and select the areas of interest.
There are six selection tools available: point selection, rectangle selection, circle selection, polygon selection, line selection, and layers selection tool. Learn more about using our selection toolbox.
- Click Done.
To edit your currently masked areas of interest, click the button in the upper-right corner of your screen, which allows you quick access to the masking tool. To remove a mask, click the X symbol next to the mask button.
