5. Click Apply to make the changes, and then click OK to close the
dialog box.
6. Back in the View, you’ll see that the appearance of the three layers has
completely changed from the flat GCS projection to the curved LCC
projection.
5.5 Navigating the View
1. AEJEE provides a number of tools for navigating around the data layers
in the View. Clicking on the globe icon will zoom the View to the extent
of all the layers. It’s good to use if you’ve zoomed to far in or out in the
View or need to restart.
