Aktuelle Version vom 26. Januar 2014, 18:49 Uhr
Das Perl-Skript makeGoogleMapsOverview.pl generiert ein KMZ-File mit der Übersicht aller Wiki-Strecken des Hauptnetzes. Zusätzlich wird die Konsistenz der Knotenpunkte (Anschlüsse) überprüft. Mit der erzeugten Radfernwege_Übersicht.kml können fehlende Anschlusspunkte schnell gefunden werden.
Einstellungen:
- my $showNodes = 0; Es werden keine Ortspunkte im Output-File gespeichert
- my $accuracy = 1000; Auflösung der Tracks in Meter.
Die generierte Datei kann als KMZ ins Wiki hochgeladen werden (siehe Datei:Radfernwege Übersicht.kmz).
