The “MapInfo Interchange Format” .mif, usually associated with the .mid file, is the export format of the MapInfo software, designed for GIS interoperability. It is a clear, well documented, well supported and stable ASCII text file.

It can be expected from GIS applications that they can correctly import MIF/MID data and that map layers in the application’s own format can be exported to MIF/MID.

MIF/MID is a preferred format for file type GIS.
