6203.2 - Satellite Derived Bathymetry – methods and possibilities

Thursday, July 6
10:50 AM - 11:10 AM
Location: Virginia A

Satellite Derived Bathymetry (SDB) is a relatively new method which uses satellite or other remote multispectral imagery for depth determination. Recent advances in satellite technology (spectral, radiometric, temporal and spatial resolution improved) have increased potential of this method as a source of hydrographic data. This method was developed in the late 1970s, but the last few years become widely available and used. SDB is a survey method founded on analytical modelling of light penetration through the water column in visible and infrared bands. SDB data has potential to become most important low cost source of marine spatial data including hydrographic data.
Procedures for different hydrographic applications are being developed. Satellite multispectral imagery at resolution higher than 30m is suitable for SDB, as this method results in an average depth per pixel.
According S-100 and S-101 multibeam echo-sounder (MBES) data typically met quality of data object - M_QUAL and the Category of Zone of Confidence attribute – CATZOC A1 (positional data accuracy of ±5 m + 5% of depth and vertical or depth accuracy of ±0.50 m + 1% of depth) while almost all SDB data was within the CATZOC C depth accuracy (positional accuracy ±500 m; depth accuracy of ±2 + 5% of depth). Available SDB data were horizontal and vertical accurate to approximately ±2-3 m.
Article will briefly describe available resources (all commercially available satellite missions - Landsat 8, Worldview-2…) used in SDB. The procedures and algorithms (Single-image multiple-image approach) as well as reconnaissance tool will be described. At the end, SDB of test area at the east coast of the Adriatic Sea will be presented.

Lysandros Tsoulos

Professor of Cartography
National Technical University of Athens

Lysandros Tsoulos is professor of Cartography at the Department of Surveying Engineering - National Technical University of Athens [NTUA] (1992-2016). He holds a degree in Surveying engineering from the University of Thessalonica (1972) and a Ph.D. in Cartography from the NTUA (1989). In 1975 he joined the Hellenic Navy Hydrographic Service [HNHS] where he worked for 17 years (Directorate of Cartography and the HNHS Computing Center). In 1992 he was elected member of the faculty at the School of Surveying Engineering - NTUA. Until September 2016 he was director of the NTUA Geomatics Center and the Cartography Laboratory. He has coordinated and managed a number of National and EU research projects. He is the author/co-author of 170 research papers on Digital Mapping and Geographic Information Science published in journals or presented in Conferences. His research interests include cartographic design, composition and generalization, expert systems in cartography, GIS, digital atlases, data and map quality issues and spatial data standards. He teaches Cartography and GIS courses at undergraduate and graduate levels and supervises a number of Masters and Ph.D. theses/dissertations. He is reviewer of papers submitted to international scientific journals and project-research proposals. He is member of the council of the Hellenic Cartographic Society and member of national and international scientific committees [International Board of Standards of Competence for Hydrographic Surveyors and Nautical Cartographers, Technical Chamber of Greece, etc.].
