Maritime and Coastguard Agency Civil Hydrography Programme 2017 data includes acoustic backscatter mosaics, H575 seabed samples and images, and sediment point and area shapefiles. The dataset was collected as part of the Civil Hydrography Programme and verified by the UK Hydrographic Office. It covers the marine area from Yell to Lerwick.
Use Cases
- Analyze acoustic backscatter mosaics to map seabed composition and texture.
- Classify sediment types using point and area shapefiles for geological modeling.
- Correlate H575 seabed sample data with backscatter imagery to validate habitat interpretations.
Strengths
- Data is verified by the authoritative UK Hydrographic Office.
- Includes multiple complementary data types: backscatter mosaics, physical samples, and sediment shapefiles.
Limitations
- Specific sample size, row count, and file formats are unknown.
- Data is from a single 2017 survey, limiting temporal analysis.
Provenance
- Source
- British Geological Survey (BGS), collected for the Maritime and Coastguard Agency Civil Hydrography Programme.
- Collection Method
- Collected as part of the Civil Hydrography Programme (CHP), likely via ship-based acoustic and physical sampling.
- Time Range
- 2017
- Freshness
- Last updated in March 2026, but the underlying survey data is from 2017.
- Geography
- Marine area from Yell to Lerwick.
