If you have downloaded our free health data layers, you may have noticed that the hospital layer includes the hospitals’ associated health system. This article will explain how you can just show hospitals from a particular health system.
If you haven’t downloaded the free health data layers or added the hospitals to your map, see: https://www.caliper.com/learning/articles/how-do-i-download-the-free-healthcare-map-layers-for-maptitude/
Once you have added the Hospital layer to your map, make sure it is the working layer and go to Selection>Select by Condition. Here, enter the following: [Health System]=”HCA Healthcare”
Note: You can replace “HCA Healthcare” with the name of the health system you want to look at.
To hide all of the other hospitals, simply click the 
button in the selection toolbar.
