GeoIndex maps contain analogue and digital airborne magnetic surveys conducted by the British Geological Survey and commercial entities. The collection includes surveys of Great Britain, the North Sea, and areas off the northwest, north, and northeast coasts. Data originates from multiple sources including the Geological Survey (GSGB), Aeroservices Inc, and Huntings Geology and Geophysics.
Use Cases
- Analyze magnetic anomaly patterns across Great Britain and offshore regions using flight line data.
- Integrate commercial analogue survey data from the North Sea with BGS surveys for regional geophysical modeling.
- Compare digitized analogue surveys with original digital surveys from Huntings Geology and Geophysics for data consistency studies.
- Map aeromagnetic data alongside other geophysical methods from local surveys for multi-parameter geological interpretation.
Strengths
- Includes data from multiple authoritative sources like the British Geological Survey and commercial survey companies.
- Covers a significant geographical area including Great Britain, the North Sea, and offshore regions to the NW/N/NE.
- Contains both analogue and digital survey types, providing historical and modern data formats.
Limitations
- Specific data volumes, row counts, column structures, and file formats are not provided in the input.
- Data integration may be complex due to the mix of analogue, digitized analogue, and digital sources from different eras and contractors.
- The description does not specify the resolution, accuracy metrics, or completeness of the individual surveys.
