Correct bathymetry measurements depend on water surface elevation, and whereas previous methods considered the water surface horizontal, our bathymetric module accounts for the curvature of the Earth in the imagery. The process is semiautomatic, reliable, and repeatable, independent of any external bathymetry data eliminating user bias in selecting bathymetry calibration points, and it can generate a fully integrated and seamless topo-bathymetry digital elevation model (TBDEM) in the same coordinate system, comparable with the band-ratio method irrespective of the regression method used for the band-ratio algorithm. The ASP output can be improved by applying a camera bundle adjustment to minimize reprojection errors and by alignment to a more accurate topographic (above water) surface without any bathymetric input since the derived TBDEM is a rigid surface. These procedures can decrease bathymetry root mean square errors from 30 to 80 percent, depending on environmental conditions, the quality of satellite imagery, and the spectral band used (e.g., blue, green, or panchromatic).<\/jats:p>","DOI":"10.3390\/rs15163950","type":"journal-article","created":{"date-parts":[[2023,8,9]],"date-time":"2023-08-09T10:21:50Z","timestamp":1691576510000},"page":"3950","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["SaTSeaD: Satellite Triangulated Sea Depth Open-Source Bathymetry Module for NASA Ames Stereo Pipeline"],"prefix":"10.3390","volume":"15","author":[{"given":"Monica","family":"Palaseanu-Lovejoy","sequence":"first","affiliation":[{"name":"Minerals, Energy and Geophysics (GMEG) Science Center, U.S. Geological Survey, Geology, Reston, VA 20192, USA"}]},{"given":"Oleg","family":"Alexandrov","sequence":"additional","affiliation":[{"name":"NASA Ames Research Center Intelligent Robotics Group, Moffett Field, CA 94035, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0907-034X","authenticated-orcid":false,"given":"Jeff","family":"Danielson","sequence":"additional","affiliation":[{"name":"Earth Resources Observation and Science (EROS) Center, U.S. Geological Survey, Sioux Falls, SD 57198, USA"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8057-4490","authenticated-orcid":false,"given":"Curt","family":"Storlazzi","sequence":"additional","affiliation":[{"name":"Pacific Coastal and Marine Science Center (PCMSC), U.S. Geological Survey, Santa Cruz, CA 95060, USA"}]}],"member":"1968","published-online":{"date-parts":[[2023,8,9]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"340","DOI":"10.1016\/j.joes.2021.02.006","article-title":"Review of near-shore satellite derived bathymetry: Classification and account of five decades of coastal bathymetry research","volume":"6","author":"Ashphaq","year":"2021","journal-title":"J.
