Data Quality
Lineage This data was originally provided as sonar video footage on CD-rom, veiwable with accompanying software (Imagenex Model 881 Sportscan Digital Sidescan Sonar V1.20). Using the latitude and longitude displayed at the beginning and end of the paths, the shapefile was made to represent the paths of the Sidescan Sonar. The shapefile represents the paths assuming travel was in a straight line from beginning to end. It is possible that the vessel wavered from this path.

The data was projected to UTM (WGS84) zone 47S using ArcView.

Positional Accuracy GA recieved little information regarding the positional accuracy of the sonar footage. Latitude and Longitude were both given to a hundredth of a minute.
Attribute Accuracy The table attributes describe the path number.
Logical Consistency The themes are used to describe the Sidescan Sonar paths.
Completeness Is complete for the Sidescan Sonar footage which was provided by PANCKI.
