Abstract

Die Genauigkeit der Vermessung von Gewässerbodenprofilen, d.h. der Berechnung von Tiefenwerten eines Gewässers, ist im wesentlichen von der Bestimmung der mittleren Schallgeschwindigkeit abhängig. Dabei werden spezielle Sondenmessverfahren eingesetzt, die sehr aufwendig sind und die Messfahrten durch Fahrtunterbrechung verzögern. Werden bei einer Messfahrt die Tracks nun so gelegt, dass sich Lotspuren auf annähernd parallelen Tracks überlappen, so lässt sich aus den Steigungen der Bodenprofile ein Korrekturfaktor berechnen, mit dem ein geschätzter Wert der mittleren Schallgeschwindigkeit verbessert wird. Eine zweimalige Iteration führt bereits zu optimalen Ergebnissen. Die Vermessung von Gewässern wird verbessert und beschleunigt bis hin zu einer Offline-Auswertung am Ende einer Messfahrt.
