To map a tide鈥恈oordinated shoreline, such as the mean sea level (MSL), information on terrain topography, bathymetry and tidal characteristics is required. In this study, IKONOS imagery was used to derive topographic and bathymetric information for an extract of the Malaysian coast and combined...
The intensity does not represent the true terrain radiance from the terrain, but it can be used for feature detection and classification [32]. With the dimensional reduction method, the 3D point cloud data are converted into a 2D image. This means that in the rasterization process, the ...

scene and the satellite’s path during image acquisition along ASC or DESC tracks. During the ascending orbit (south to north), the SAR sensor faces east, while during the descending orbit (north to south), it faces west. This means that the SAR signal reaches the terrain with different ...
During the first implementation, this was used to map the impact of a storm along 100 km of beaches in the Gulf of Valencia and the subsequent recovery [30]. Obtaining accurate shorelines is crucial in the use of the Landsat series for mapping the past with a coastal evolution indicator [...
The results further revealed that tools for shoreline change analysis have changed from a simple beach transect (0.1%) to the utilization of geospatial tools such as DSAS (14.6%), ArcGIS/ArcMap (13.8%), and, currently, machine learning (5.1%). Considering the benefits of these geospatial ...
Various extents of focal elements at each binary map can be seen when zooming into the yellow rectangle site. We plotted the area of focal elements to explore information on the extent of random sets (see Figure 10). From the plot in Figure 10, we can see that 𝑆2−12S2-12, ...
