DATETIME DATE No No Active 2012-2015 data only: The UTC date and time in m/d/yyyy h:mm:ss 24-hr format. DEPTH NUMERIC No No Active Depth in meters (negative values) EST_H_ERROR NUMERIC No No Active 2012-2015 data only: estimated horizontal position error in meters. Values range from 0-130. FIXTYPE NUMERIC No No Active 2012-2015 data only: the fix/GPS quality indicator (1 or 2). 0= Invalid fix 1 = GPS fix 2 = DGPS fix GPSMODEL TEXT No No Active 2012-2015 data only: GPS Map 178c used on the Safe Boat small boat 2012 during ASRAMP 2012. GPS Map 740s used on the Steel Toe small boat in 2012 in Tutuila, American Samoa only. GPS Map 3006c used on the Rubber Duck small boat from 2012 to 2015. TIME TIME No No Active 2016 to present: the UTC time in h:mm:ss 24-hr format. ISLAND TEXT No No Active 3-letter code for the island/atoll where the data were collected in the U.S. Pacific Islands Region. See the lookup table included in the distribution section named LIST_OF_ISLANDS.csv LATITUDE NUMERIC No No Active Y-coordinate in decimal degrees, WGS 84 LONGITUDE NUMERIC No No Active X-coordinate in decimal degrees, WGS 84 REGION TEXT No No Active One of five areas in the U.S. Pacific Islands Region where data were collected. PRIA = Pacific Remote Island Areas AMSM = American Samoa NWHI = Northwestern Hawaiian Islands MHI = Main Hawaiian Islands MARI = Mariana Archipelago SATELLITES NUMERIC No No Active 2012-2015 data only: the number of satellites tracked/in use at the time of the fix, that is, when the position is calculated/recorded. Values range from 0-12. Null values only occur with fixes acquired from March 2014 to April 2015 with the GPSMAP 3006c. SPEED NUMERIC No No Active 2016 to present: velocity of the small boat at the time of the fix in meters per second. HDOP NUMERIC No No Active 2012-2015 data only: horizontal dilution of precision. 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. Values range from 0.7 to 12. HDOP = 99, no satellites were tracked/in use gov.noaa.nmfs.inport:51188 Annette DesRochers 2018-01-12T19:48:40 SysAdmin InPortAdmin 2022-08-09T17:11:39 2018-04-27 Pacific Islands Fisheries Science Center PIFSC 1845 Wasp Blvd. Honolulu HI 96818 USA 808-725-5300 https://www.pifsc.noaa.gov 8:00 a.m. - 4:30 p.m. 1001 Public No 2018-04-27 1 Year 2019-04-27
