What is an M77T file?

Data file created and used by GEODAS ReFormat to MGD77T, a program used to format geophysical data into the Marine Geophysical Data Exchange (MGD77T) format; contains bathymetry data in ASCII text format; includes the survey ID, date, timezone, water depth, and latitude and longitude coordinates.

More Information

M77T data files are created from raw data collected by marine researchers using InfoBank, a structured information storage scheme of databases and software. The raw data is collected by researchers studying underwater depth of lake and ocean floors, which is known as bathymetry. A M77T and .H77T file, along with other metadata files, are used to transmit data to and from a data center for analysis.
