Maps in 3D make it easier to reference your surroundings.
Lite purple = up to 250ft in height
Green = 251ft – 500ft in height
Blue = 501ft – 1,000ft in height
Deep purple = 1,001ft – 1,500ft in height
For 3D terrain we have included contours and height indicators, so you can view the height of the terrain.
This is meaningful if you need to be rescued from mountainous terrain, and acts as a check- safe, so rescuers know what equipment and resources required i.e. ropes, specialist vehicles, specialist personnel.
