Plugin for QGIS that checks a given vector layer with planned flight paths/flight areas for conflicts with nearby geographical zones in Germany and returns 2 vector layers, one with intersecting zones and one with closeby zones. Distances and links to more information about the restrictions for each zone can be found in the attribute tables.
Known issues: Running this plugin can take up to 1-2 minutes, getting no response during this time isn't unusual and doesn't necessarily indicate a crash.
Source for geodata: DFS, BKG [2022] via www.dipul.de and their WMS service.
