I learned a thing. I'm messing around with a way of showing height of an aircraft without just reading the numbers. Lower the cognitive barrier for someone using the map. I tried drop shadows that change based on altitude but they read very poorly over the map so I'm scrapping that idea. I don't want to use color as I want high threat targets to be color coded for traffic alert info when flying. So these leaves perhaps shape / size to play with. Here is a picture of the map with drop shadows. Not great. I'm not much of a designer but I'll prototype some things and see what reads best. #godot #avgeek #aviation
