Obstruction Mode determines how AirMap displays the height of ob-
structions on the Map Page. If you change it to AGL (Above Ground
Level), then the Map Page will show an obstruction's height above the
surrounding terrain. If you set it on MSL (Mean Sea Level), the Map
Page will show the obstruction's altitude above sea level. Note that this
setting affects only the height of obstructions displayed on the Map Page.
