Answer:
A location in a digital map.
Step-by-step explanation:
GIS refers to Geographic Information System. This is a method that can sometimes be employed in hospitals and other health centers in order to better monitor and respond to patients. GIS allows health workers to identity health trends in different regions. It can also be useful when it comes to tracking the spread of diseases and providing better services. However, for any of these to work, health information would have to be tied to a location in a digital map.
