| Table | Column | Column Comments |
|---|---|---|
| COMPLETE_SEISMIC_TRACKS | PROJECT | Project Number of the seismic survey. |
| COMPLETE_SEISMIC_TRACKS | LINE | Seismic Line Number. This is the seismic line number assigned by the company. Examples: "T-14", "USGS12A". Some Line Numbers, such as "T-14" occur in more than one seismic survey. |
| COMPLETE_SEISMIC_TRACKS | OACID | Operational Activity Code ID. Related to the OAC field in the COMPLETE_SEISMIC_SURVEYS table. Consists of the OAC with a number appended to it which corresponds to the line number. Example: "SAQ294" represents line number 294 in the SAQ seismic survey. This system was dropped in 1979, therefore only 97 of the hundreds of seismic surveys in the dataset have OACID numbers. |
| COMPLETE_SEISMIC_TRACKS | STRT | Start Shotpoint. This is the shotpoint number at the start of the line. It can be a negative number, such as "-100". The value is usually "1". |
| COMPLETE_SEISMIC_TRACKS | END | End Shotpoint. |
| COMPLETE_SEISMIC_TRACKS | DIST | Distance from the start to the end shotpoints. This is the distance, in kilometers, along the line from the first to the last shotpoints. Example: "13.487". |
| COMPLETE_SEISMIC_TRACKS | MIN_LAT | Minimum Latitude. The latitude of the southernmost point on the seismic line. |
| COMPLETE_SEISMIC_TRACKS | MAX_LAT | Maximum Latitude. The latitude of the northernmost point on the seismic line. |
| COMPLETE_SEISMIC_TRACKS | MIN_LONG | Minimum Longitude. The longitude of the westernmost point on the seismic line. |
| COMPLETE_SEISMIC_TRACKS | MAX_LONG | Maximum Longitude. The longitude of the easternmost point on the seismic line. |
