I desperately need a map of an airport aerodrome like the ones used for tracking the movements of aircraft similar to the picture below and I don't know where I can find these ones :
Airport Diagrams such as this one of KPNE
are published here on the FAA website as well as in in the airport facilities directory. These are up to date and considered legal for navigation as far as I know. If you are looking for them in another type of format that may be tough, you can try reaching out to the specific airports or the FAA directly.
OpenStreetMap is a good place to start.
I've used it for a project with real aircraft data and found that the OSM map of the airport I was interested in had a small offset. Using JOSM I was able to correct for the offset and add missing taxiways and additional features.
I have also tried to use PDF based airport diagrams from various Aeronautical Information Publications (AIP) but I was not successful in extracting the specific elements I was interested in.
