Open Digital Shoreline Analysis System: ODSAS v1.0

In this study, we propose a new baseline and transect method, the open-source digital shoreline analysis system (ODSAS), which is specifically designed to deal with very irregular coastlines. We have compared ODSAS results those obtained using (DSAS). Like DSAS, our proposed method uses single parallel offers user different smoothing spacing options generate transects. Our differs from DSAS in way that transects’ starting points orientation are delineated by combining raster vector objects. SAGA GIS R, both free software programs. paper, delineate workflow, apply it ten study sites along Galician coastline (NW Iberian Peninsula), compare one DSAS. show how produces similar values of changes terms most common indicators at aggregated level (i.e., all transects), but differ when transect-by-transect level. argue herein explicitly requesting define minimum resolution important reduce subjectivity method.
