What is a .M77T file?
The file extension .M77T refers to a type of data file known as an MGD77T Data File. This file format is specifically used to store geophysical data related to the study of underwater environments, such as lakes and oceans. The data within these files is formatted in ASCII text and includes important information like the survey ID, the date of the survey, the timezone, water depth, and the geographical coordinates (latitude and longitude) of the surveyed area.
These .M77T files are created using a program called GEODAS ReFormat to MGD77T. This program is designed to convert raw geophysical data into the MGD77T format, which is a standard format for exchanging marine geophysical data. The raw data is typically collected by marine researchers who use a system called InfoBank. InfoBank is a comprehensive set of databases and software tools used to manage and store data about the underwater depth of lake and ocean floors, a field of study known as bathymetry.
In addition to .M77T files, researchers may also use .H77T files and other types of metadata files. These files are essential for transmitting data to and from data centers where the information is analyzed further.
It is important to note that the GEODAS ReFormat to MGD77T software, which is used to create and open .M77T files, is no longer available for download. This means that accessing and using .M77T files might require specific legacy software or alternative programs capable of handling MGD77T formatted data.
