|Full name||MapInfo Data File (DAT)|
The MapInfo data file (.DAT) stores the feature attribute data in a MapInfo dataset's file group in dBase (III, IV, or V) format.
The .DAT file is a heterogenous format and combines binary and ASCII data. The header contains binary data while the record data is in ASCII (except for binary record data objects like images and/or Binary Large Object Data BLObs).
|Relationship to other formats|
|Component of||MapInfo, MapInfo dataset format|
|Subtype of||DBF, dBASE Table File (DBF). May use file versions compatible with dBase III, IV, or V.|
|LC experience or existing holdings|
|Disclosure||The MapInfo dataset format, which comprises a group of related files, is developed and regulated as a proprietary GIS dataset format used in MapInfo products. MapInfo's component .DAT file is a dBASE Table File in dBase (III, IV, or V) format which is well documented. As of August 2011, the MapInfo products are maintained and distributed by Pitney Bowes Business Insight.|
|Documentation||No complete specification is available for the MapInfo format, nor for its component .dat file. A March 2000 article in Spatial News, Notes on the MapInfo® Native table format, provides useful information on the MapInfo format, including the statement, "The structure of MapInfo® .dat file is virtually identical to dBase IV data format." See DBF for documentation for dBASE Table Files in general.|
|Licensing and patents||See DBF.|
|External dependencies||None for MapInfo_DAT as an individual file.|
|Technical protection considerations||None|
|Normal functionality||See MapInfo.|
||MapInfo dat files are in the dBase format, but do not use the usual .dbf extension for such files.|
