Sound Velocity Profile
If you need the speed of sound value at a certain node depth from the current profile, please go to group RESULT DATA, category Nodes and select sub item SVP
| Sub Item | Description | Value Type | Properties |
|---|---|---|---|
| Id | Id of the current sound velocity profile: an integer value automatically issued by the Controller. Same value as seen in the Echosounder Settings, Velocity Profile, General Information page:
Lowest value will be 1 for the oldest available sound velocity profile. | integer | |
| Time | UTC date and time when the profile was updated (from Import, Manual, Logger, etc.) Same value as the Date and Time in the Echosounder Settings, Velocity Profile, General Information page. | time | |
| Age | Difference between now and the time of the profile update. | timespan | |
| Distance | Horizontal range (in survey units) between the current Steered Node position and the location of the profile. The location of the profile is entered in the Echosounder Settings, Velocity Profile, General Information page. Value remains empty when there is no valid steered node position. | double | |
| Entries | The number of depth readings for the current sound velocity profile. | integer | |
| Easting | Grid position (on Survey Datum) of the profile as entered in the Echosounder Settings, Velocity Profile, General Information page. | double | |
| Northing | Grid position (on Survey Datum) of the profile as entered in the Echosounder Settings, Velocity Profile, General Information page. | double | |
| Latitude | Geographical position (on Survey Datum) of the profile as entered in the Echosounder Settings, Velocity Profile, General Information page. | geo | |
| Longitude | Geographical position (on Survey Datum) of the profile as entered in the Echosounder Settings, Velocity Profile, General Information page. | geo | |
| Mean | The mathematical mean value of the current sound velocity profile for the selected data type (parameter). Value remains empty when the selected data type is not available in the current profile. | double | Parameter
