MapInfo Mid/Mif file Format

The MapInfo Interchange Format (MIF) is a versatile format which allows generic data to be attached to a variety of graphical items. It is an ASCII format, so it is editable, relatively easy to generate, and works on all platforms supported by MapInfo.

Mapinfo data is in two files – the graphical data resides in a .MIF file and textual data is contained in a .MID file. The textual data is delimited data, with one row per record and either Carriage Return, Carriage Return plus Line Feed, or Line Feed between lines.

The MIF file has two areas – the file header area and the data section.  Information on how to create MapInfo tables is in the header; the graphical object definitions are in the data section.

Both the Mid and Mif files will need to be present before the data is imported into QuickMap. For more info on the file format visit www.mapinfo.com
