Wie kann mit Java die Anzahl der Flugzeuge in der jeweiligen Höhe weltweit in real time ermittelt und mit OpenStreetMap via uMap visualisiert werden? – Wenzlaff.de

Wie vor zwei Jahren hier schon mal beschrieben hat sich nicht viel geändert.

Aber es gibt eine neue Version (1.3.0) der Rest API, die wir verwenden wollen. Dazu die Maven pom.xml updaten:

 <groupId>org.opensky</groupId>
    <artifactId>opensky-api</artifactId>
    <version>1.3.0</version>

<groupId>org.opensky</groupId>

<artifactId>opensky-api</artifactId>

Hier der aktuelle Lauf:

Flugbereich in Meter ; Flughöhe in Meter 
Parken 0    ; 303
   1-500    ; 320
 500-1000   ; 355
1000-2000   ; 410
2000-3000   ; 321
3000-4000   ; 310
4000-5000   ; 233
5000-6000   ; 234
6000-7000   ; 237
7000-8000   ; 306
8000-9000   ; 340

Es sind also 6559 Flugzeuge weltweit in der Luft! Hier die paar Zeilen Java Code die dafür nötig sind:

Damit wurde nun eine aktuelle KML Datei erzeugt, und mit uMap und einer OpenStreetMap Karte visualisiert (siehe Foto oben), alles weltweit hier. Es muss ja nicht immer Google sein.
