Satellite image processing for the coarse-scale investigation of sandy coastal areas

In recent years, satellite imagery has shown its potential to support the sustainable management of land, water, and natural resources. In particular, it can provide key information about the properties and behavior of sandy beaches and the surrounding vegetation, improving the ecomor-phological understanding and modeling of coastal dynamics....

4D objects-by-change: Spatiotemporal segmentation of geomorphic surface change from LiDAR time series

Time series of topographic data are becoming increasingly widespread for monitoring geomorphic activity. Dense 3D time series are now obtained by near-continuous terrestrial laser scanning (TLS) installations, which acquire data at high frequency (e.g. hourly) and over long periods. Such datasets contain valuable information on topographic...

High-Frequency 3d Geomorphic Observation Using Hourly Terrestrial Laser Scanning Data Of A Sandy Beach

Geomorphic processes occur spatially variable and at varying magnitudes, frequencies and velocities, which poses a great challenge to current methods of topographic change analysis. For the quantification of surface change, permanent terrestrial laser scanning (TLS) can generate time series of 3D point clouds at high temporal and spatial...

Intertidal beach level estimation from video images

Since 1992 nearshore hydrodynamics and coastal morphology have been studied from ARGUS video images, collected every hour at eight beach locations worldwide. Identification of the waterline from these images would enable us to obtain an impression of the intertidal beach bathymetry, and hence to monitor intertidal beach morphodynamics. In this...
