Determining the coordinate system for an existing map

Every map and scene you create in ArcGIS Pro makes use of a coordinate system in order to display data in a location. However, it not only impacts how and where features are displayed but also what you can do with the map. The coordinate system used by a map can impact whether you can share it as a web map via ArcGIS Online, how well layers overlay one another, and more. Therefore, it is important to know what coordinate system your map is using.

The first layer you add to the map will define the coordinate system for that map, but what if you are working with an existing map, perhaps even one that was created by someone else? How do you determine the coordinate system for the existing map you are working with? In this recipe, you will learn how to determine which coordinate system has been assigned to an existing map.
