Description

Singlebeam bathymetry for Timor-Leste

Entity Information

Entity Type
Data Table

Data Attribute / Type Description
Region
TEXT 		2012: The region location in the pacific where surveys were conducted (Coral Triangle)
Island
TEXT 		2012: The island location in the pacific where surveys were conducted (Timor-leste)
LocalTime
DATETIME 		2012: GMT (Greenwich Mean Time) +9 for local time in Timor-leste (mm/dd/yyyy hh:mm)
GMTime
DATETIME 		2012: Greenwich Mean Time (mm/dd/yyyy hh:mm)
Latitude
NUMERIC 		2012: Y-coordinate in decimal degrees
Longitude
NUMERIC 		2012: X-coordinate in decimal degrees
SeafloorDepth
NUMERIC 		2012: Depth in meters, 0 to -30m
FixType
NUMERIC 		2012: Type of position fix (0 = No fix, 1 = GPS fix, 2 = DGPS fix)
NumSatellites
NUMERIC 		2012: number of satellites in use (tracked by the GPS at the time of the position was fixed/recorded)
HDOP
NUMERIC 		2012: horizontal dilution of precision, or the relative accuracy of the horizontal position. A measure of the geometric quality of a GPS satellite configuration in the sky. HDOP is a factor in determining the relative accuracy of a horizontal position. The smaller the DOP number, the better the geometry.
DATETIME
DATETIME 		2013: the date and time (GMT) in mm/dd/yyyy hh:mm:ss format
SEC
NUMERIC 		2013: sub-seconds (ss.0)
X
NUMERIC 		2013: Longitude in decimal degrees
Y
NUMERIC 		2013: Latitude in decimal degrees
Z
NUMERIC 		2013: Unknown
TYPE
TEXT 		2013: Type of record, D = Depth only, L= Depth and Location (depth is linked to GPS fix). There are two 'type = D' records for every 'type = L' record, because the sonar pings every half second, which is more frequent than the GPS.
TIDE
NUMERIC 		2013: Not used
DEPTH
NUMERIC 		2013: corrected depth in meters (20 cm or 30 cm correction applied, distance from instrument to surface of water)
QA
INTEGER 		2013: Records with a type = L indicate the depth record includes the GPS location and has a QA = 1 (NMEA tag for GPS fix). For the 'type=D' records, the higher the QA, the better the return signal strength. QA=70 is low signal strength (not as good), QA = 130 is high return signal strength (better).
