Data sources
To create L3 products, the key data required is L2 MBES containing backscatter, typically stored in the proprietary format of the processing software, such as Caris HDCS_Data. This L2 data is essential for producing accurate backscatter mosaics and other L3 products, as it enables precise corrections and calibrations within the software. Alternatively, L2 data can be stored in open-source formats like Generic Sensor Format (GSF), provided the backscatter is included, improving interoperability across platforms. Regardless of format, L2 MBES data serves as the foundation for L3 products, which are crucial for seafloor mapping, habitat classification, and geological studies.
Processing steps
While some processing software retains L2 MBES backscatter data in proprietary formats during the mosaicking process, others only preserve the final L3 MBES backscatter. This variation in data retention can significantly influence how the data can be accessed, analysed, and reused in future projects.
