How do I find out how much area each map covers? Salina Morrow September 25, 2019 at 9:42 am I drew a box around my area of interest and it says there are 3 items. How do I find out what area each item covers? Salina Morrow September 25, 2019 at 9:49 am If you hover your mouse over the item number, you’ll see a red box over the map that highlights its coverage. Also, you can click the “show grid” icon in the item selection to see all item boundaries at once. This reply was modified 1 year ago by Salina Morrow. You must be logged in to reply to this topic.
