Process-Oriented Geomorphometry for Submerged Terrain // Derives, organizes, summarizes, and visualizes terrain metrics from bathymetric and elevation rasters for submerged-landscape geomorphometry. Tools support terra-based raster preparation, slope and aspect decomposition, terrain position, rugosity, curvature, depth-band summaries, transect extraction, isobath- corridor analysis, and model-ready summaries for seafloor classification, habitat mapping, shelf-margin analysis, and spatial modeling. Methodological context for geomorphometric terrain analysis is provided by Lindsay (2016) doi:10.1016/j.cageo.2016.07.003.
