FAQ
MID to CG4 Conversion
What are MID files?
MID is the attribute table of MapInfo's interchange format, in which map data are exchanged as a pair of text files. The shapes of the objects, such as points, lines, and areas, are kept in a file with the .mif extension, while the .mid file holds the descriptive data about the same objects, such as names, codes, numbers, and dates, in the form of a simple table. MapInfo is a desktop GIS program widely used in business, telecommunications, and local government, and this pair of files is its open way of passing data to other programs, because both files are plain text and can be read and corrected in any text editor. The .mid file is not useful by itself, since it contains no coordinates.
What are CG4 files?
CG4 is a raster format associated with CALS (Continuous Acquisition and Life-Cycle Support) — a program initiated by the US Department of Defense to capture and link military data. CG4 is compatible with a very limited number of digital graphics programs. Files with this extension contain a bitmap that often uses the CCITT4 compression, which is an old fax machine standard used for black-and-white images.
