An identification service that utilizes high-resolution satellite imagery and SAR to locate and characterize submerged or surfaced obstacles, shipwrecks, and navigational hazards.

TCarta’s Seafloor Feature and Hazard Detection service utilizes high-resolution multispectral satellite imagery (MSI) and Synthetic Aperture Radar (SAR) to locate and characterize submerged and surfaced obstacles, shipwrecks, and navigational hazards in shallow waters. This multi-sensor approach provides a comprehensive view of the marine littoral environment,  where MSI is used to visualize features beneath the water's surface in optically clear areas and SAR identifies above-water features and surface-piercing hazards. SAR is particularly effective for detecting "dark" targets, such as derelict vessels or navigational markers, regardless of cloud cover or lighting conditions. By analyzing spectral reflectance and radar backscatter patterns, TCarta identifies anomalies including anthropogenic structures, rock pinnacles, and abandoned vessels.
