Figure 3.36 Side scan sonar target displayed as a GeoTIFF. Note the sonar trace in (a) is geo- graphically coordinated by the processing software but does not allow for the removal of the water column (the dark center line). In this case positions on the GeoTIFF are not strictly correct (pseudo-georeferenced). In case (b) using SonarWeb, the processing has removed the water column thus allowing for slope correction. Any position on this GeoTIFF will be cor- rectly georeferenced.
