I need to write a piece of software in order to display on a map flight routes and airways. I would therefore like to know if there is a standard way of displaying this kind of information (in particular the kind of icons used for displaying waypoints, departure and arrival airports and so forth).
For example, by Googling a bit I have the chart shown below:
Could someone point me to any additional sources of information that I could use.
I am particularly interested in the icons/shapes to use as well as the kind of relevant information to show. The idea would be that the map is recognizable at once by a professional pilot and provides him all the relevant information.
