E-Learning Module: SAET Shoreline Analysis and Extraction Tool

The Shoreline Analysis and Extraction Tool, SAET V 1.0 is a software developed in Python language focused on the automatic extraction of shorelines from optical satellite imagery (Sentinel-2 and Landsat-8). Its main algorithm is based on the shoreline sub-pixel detection approach, adapted from the SHOREX system (Pardo-Pascual et al. 2012 & 2018; and Sánchez-García et al., 2017). This software allows obtaining the pre-storm and post-storm shoreline, enabling to make a comparison and to detect the erosion impact of storms on low-lying beaches.
