UK Hydrographic Office data from the 2017 Thames Routine Resurvey includes acoustic backscatter mosaics, seabed samples with images, and sediment shapefiles. The collection contains verified H575 seabed samples and sediment point and area classifications.
Use Cases
- Analyze acoustic backscatter mosaics to map seabed texture and composition variations in the Thames.
- Classify sediment types using point and area shapefiles for geological and habitat modeling.
- Correlate H575 seabed sample images with backscatter data to ground-truth acoustic interpretations.
- Use verified sediment area shapefiles for input into coastal erosion or sediment transport studies.
Strengths
- Data verified by the authoritative UK Hydrographic Office.
- Includes multiple complementary data types: mosaics, physical samples, images, and shapefiles.
Limitations
- Specific sample counts, spatial resolution, and file formats are unknown.
- Data is from a single 2017 survey, limiting temporal analysis.
