In the US, enroute ATC facilities use a combination of public and proprietary data. Airports, low altitude routes, and high altitude routes are drawn using publically available information. Sector boundaries, range marks, extended center lines, etc are all custom designed and adapted to specific maps. The custom information is not readily available to the ...
Stelios is pointing you in the right direction: the video maps incorporate elements from the various published charts but are not a direct copy of any of them (and are not updated nearly as often).
In my experience at a TRACON in the United States:
There are many different maps we can select, including no map (a blank scope). Which information is separable (...
The question as it's phrased right now isn't clear if it's asking for the type of data displayed or the source of the data.
For the first case it has already been answered but I will reiterate for the sake of completeness:
Points (waypoints, airports, VFR points etc)
Navaids (VOR, ILS, NDB etc)
Coastline and border line
Range circles ...
You are right and wrong both. The screens show of course different information depending on the role of the controller, keep that in mind.
For example a sector controller responsible for high altitude traffic would see a different screen from his colleagues handling terminal traffic and the ground controller would see a different screen again.
The data is ...
Here is an explanation that I read and I liked the most as I think it better explains the role of the intermediate segment and thus the intermediate fix. Skybrary in the IAP page mentions:
Intermediate approach segment - this segment usually begins at the intermediate fix (IF) and ends at the final approach fix (FAF) or final approach point (FAP). Here the ...
