Der ZDM Web Map Service (WMS) zeigt die Daten von Aus- und Neubauvorhaben an den Bundeswasserstraßen im Zuständigkeitsbereich der Generaldirektion Wasserstraßen- und Schifffahrt Standort Kiel. Dieser Service ist ein öffentlicher und kostenfreier Dienst der Wasser- und Schifffahrtsverwaltung des Bundes.

Die Vermessung von Topographie mittels Laserscanbefliegung (ALS) ist eine etablierte und effiziente Methode zur großflächigen Erfassung von Höhendaten mit hoher Genauigkeit. Im deutschen Wattenmeer wird ALS häufig zur Vermessung der topographischen Höhen im Wattenmeer eingesetzt, z. B. bei jährlichen Messkampagnen im Bereich der Außenelbe. Die Vermessung unterhalb der Wasseroberfläche ist für Laserscanmessinstrumente jedoch herausfordernd aufgrund von Trübung im Wasser. Daher erbringen beflogene Höhenvermessungen insbesondere auf vorübergehend trockenen Gebieten wie beispielsweise Watt oder Salzmarschen die besten Ergebnisse. Um die räumliche Abdeckung einer Befliegung zu maximieren, wurden in diesem Use-Case die räumlich variablen Eintrittszeiten des Tideniedrigwassers aus numerischen Modelldaten abgeleitet, um so die Planung einer Befliegungsroute auf minimale Wasserstände zu optimieren.
