APPLICABILITY STUDY OF AIRBORNE LASER BATHYMETRY (ALB) METHOD FOR RIVER SURVEYING

Abstract

The river surveying, so far has few issues such like "the data between survey line cannot be acquired" or "difficulty in high frequency".

On the other hand, Airborne Laser Bathymetry (ALB) surveying is performed in seashore. ALB surveying is a technology to measure the water bottom in 3D with an aircraft mounted with an Oscillator which sends a green laser that permeates water.

This article mentions the study of applicability in river surveying to increase the efficiency and sophistication of river surveying. The study was implemented by surveying the target river with ALB to evaluate the ALB surveying as an alternative from river surveying, by making accuracy assessment and correlation analysis of the water clearness from the survey results.
