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.<br>
<u>'''MIF File'''</u><br>
The .MIF file contains information on the projection, data attributes and types as well as the geographic information contained in the table. An example .MIF file is given below. Lines 1 to 3 are header information, line 4 defines the projection of the table. Line 5 specifies the number of associated data attributes. A separate line follows for each attribute column (in this case 1), this defines the type and length of this field (in this case we have an attribute named "Comment" which is a character field of length 250. The 7th line ("Data") signals the start of the GIS data.
