Can't open .MGD77 file? Are you wondering what it contains? On our site we will explain to you what this file is, what it is used for and what software opens the .MGD77 file.
.MGD77 file extension is created by National Geophysical Data Center. .MGD77 has been classified as Data Files. The format of .MGD77 file is Text.
Data file saved in the Marine Geophysical Data Exchange (MGD77) format; contains geophysical data in ASCII text format; includes the survey ID, date, magnetics data, timezone, observed gravity, latitude and longitude coordinates, and water depth.
The MGD77 data format was first developed in the 1970s by the National Geophysical Data Center (NGDC) to exchange digital underway geophysics data. Today, it is used as an exchange format for geophysical data, which includes magnetics, bathymetry, gravity, and seismic navigation. MGD77 files are created from raw data collected by marine researchers studying underwater depth of lake and ocean floors. The data is stored in InfoBank, a structured information storage scheme of databases and software, and then exported in the MGD77 format to transmit data to and from a data center for analysis.
The MGD77T format is a new revision of the MGD77 format. It allows space savings, expanded field lengths, and easier import into other programs. This format uses the .M77T file extension.
