The navigation polyline shapefile records the trackline followed by the Canadian Coast Guard ship Frederick G. Creed in the 1998 survey of the Historic Area Remediation Site. The tracklines can be used to identify line spacing, trackline orientation, and the location of data collection. The 1998 survey was carried out along tracklines running north-south and spaced about 100 m apart. The attributes record the latitude, longitude, date, and time at the start of each line.
