Satellite-Derived Bathymetry Maps: Making Waves in GIS

Depending on the size and scale of a marine survey, bathymetry data can come with a prohibitive price tag. Traditional data acquisition methods—such as multi-beam sonar and airborne lidar—are effective, but can lead to significant cost and logistical complexity.

In this episode, Amy Anfinrud from TCarta joined us to share the operational benefits of Satellite-Derived Bathymetry maps (SDB). We discussed the utility of their free Global Marine Basemap and the precision of their premium SDB data offerings integrated into Global Mapper®.

Tune in to learn why satellite-derived bathymetry maps are a great resource for geospatial, hydrographic, and coastal mapping professionals.
