Map Scalebar Layer
The Map Scalebar Layer, which is available in all releases of JMARS, displays a scalebar in the Main View that automatically shows the correct scale for the map being viewed. This layer is extremely helpful when taking screenshots from JMARS.

- Open the Map Scalebar Layer: In the Layer Manager, choose "Add New Layer" -> "Map Scalebar"
- The scalebar will appear in the lower right-hand corner of the Main View.
- Change the Location of the Scalebar: Users can change the location of the scalebar within the Main View by left-clicking and dragging it to a new location.
