A trackline is a line outlining the track undertaken by the seabed survey vessel and usually collected from the Automatic Identification System (AIS) transponder on board the vessels in the INFOMAR survey fleet.Each line geometry contains line number, vessel name, survey name, leg number, year and length.Statement on the level of data processed and quality control, limitations on reliabilitySee lineage statement for full data processing history. INFOMAR products generated to meet International Hydrographic Organization (IHO) standards to ensure gridded data positional accuracy in the horizontal (XY) and vertical (Z) frame.Arrangement of data Data available as a line geometry spatial dataset with appropriate attribute metadata.Spatial and temporal resolution of data within the datasetVector line dataset contains tracklines captured between Marchand November2018.Length of time series, recordings, miles of track or other units as appropriate44,392kilometers of tracklines.Amount of data expressed in number of stations, sites, observations, cores, months of recordings, miles of track or other units as appropriate.
