Import SeaDAS Track Data

Import SeaDAS Track Data

As another special case of CSV import, BEAM/Visat supports the import of SeaDAS (SeaWiFS Data Analysis System) ship track data. SeaDAS is a comprehensive image analysis package for the processing, display, analysis, and quality control of ocean color data. It has been developed within the NASA SeaWiFS (Sea-viewing Wide Field-of-view Sensor) Project. Note that BEAM only supports the import of track data generated with the SeaDAS versions 6.x.

In principle, these ship track files are also CSV files, but have an extremely simple layout with three columns only: The first two columns contain the vertex points latitudes and longitudes, respectively, and the third column gives the values of a single data quantity (such as a ship-based radiometer measurement). These files contain no header, all numbers are separated by the 'tab' character.
