Integrated topobathy datasets, delivered as a digital elevation model, create a holistic view of the littoral zone by merging topography and bathymetry without data gaps or artificial offsets.

Seamless, high-precision "land-to-sea" Digital Elevation Models (DEMs), Topo-Bathy products integrate marine datasets such as SDB and Bathy Models and terrestrial DEMs. These best-available integrated datasets are critical for coastal engineers and disaster preparation, as they provide the precise beach topography and nearshore bathymetry needed for project reconnaissance and modeling floods or storm surges. The resulting high-precision product offers a holistic view of the littoral zone, ensuring the critical transition from land to sea is represented without data gaps or artificial offsets, and is flexibly delivered in GIS-ready formats.
