MapInfo File Formats

There are a number of files that make up a MapInfo Table. The minimum files for a GIS map object with data are:

• .DAT
• .ID
• .MAP
• .TAB

There are a number of additional files types that may be present, these include: .IND, .TDA, .TIN and .TMA.

TUFLOW utilises the MapInfo Interchange Format files for MapInfo GIS inputs. The MapInfo interchange format consists of a pair of files with the extensions .MIF and .MID. Both of these files are text files (and can be viewed in a text editor). Whilst knowledge of the file formats is not necessary for TUFLOW modelling, advanced users can take advantage of the nature of the file formats to manipulate these datasets.
