Combining angular response classification and backscatter imagery segmentation for benthic biological habitat mapping
Backscatter information from multibeam echosounders (MBES) have been shown to contain useful information for the characterisation of benthic habitats. Compared to backscatter imagery, angularExpand

ASSESSMENT OF MULTIBEAM BACKSCATTER TEXTURE ANALYSIS FOR SEAFLOOR SEDIMENT CLASSIFICATION
Abstract. Recently, there have been many debates to analyse backscatter data from multibeam echosounder system (MBES) for seafloor classifications. Among them, two common methods have been usedExpand

Analysis of acoustic signal from RoxAnn echosounder and side scan sonar for coral reef identification
Coral reef plays important role for marine biodiversity of our coastal areas. The need of spatial knowledge and extents of these habitats is a fundamental step in assessing the impacts ofExpand
Free broadcast DGPS service for marine users: how good is it?
Differential Global Navigation Satellite System (DGNSS) radio beacon is a system designed to aid safety in marine navigation. In comparison to a terrestrial navigation or any other directionfindingExpand
LADGPS and WADGPS: applications, working procedures and accuracy for hydrographic surveying
The Global Positioning System (GPS) has been used widely for positioning in marine navigation including in hydrographic surveying task. Advanced techniques such as Differential GPS (DGPS) can be usedExpand
EXTRACTION OF ELEMENT AT RISK FOR LANDSLIDES USING REMOTE SENSING METHOD
Abstract. One of the most critical steps towards landslide risk analysis is the determination of element at risk. Element at risk describes any object that could potentially fail or exposed toExpand
