In order to support the
core swath sonar research that is active within the Ocean Mapping Group, a UNIX
based processing and analysis package (SwathEd) is maintained and continually upgraded.
This package contains the following functionality:
- Importation of a wide variety of swath sonar data
- Navigation editing and merging
- Automated and Interactive bathymetric cleaning
- Interactive by swath
- Interactive by area
- Automated by single swath
- Automated w.r.t. mean surface
- Weighted gridding, reflecting local beam footprint
- Reapplication or modification of water column correction
- Extraction and analysis of motion residuals
- Construction and enhancement of backscatter data
- Correction for gain changes
- Correction for pulse length changes
- Correction for beam pattern residuals
- Correction for grazing angles
- Registration (mosaicing) of backscatter data
- Calibration (Patch Test, Reference Surface, DelayEditor)
These software ideas and modules have been incorporated in commercial swath sonar processing packages developed by our sponsors including:
- Caris HIPS/ SIPS
- Seabeam SeaView
- NRL HMPS
- Simrad Neptune, Poseidon
- C&C Hydromap
In addition modules of the software are used as-is by the following sponsors:
