File listing
-----------------

The following files are also associated with .TAB files: .DAT, .ID, .MAP. An
example is::

	border.DAT 
	border.ID 
	border.MAP 
	border.TAB

The term MID/MIF refers to files with .MID and .MIF extension.

Data Access / Connection Method
----------------------------------

TAB and MID/MIF access is available in MapServer through OGR.

*  The CONNECTIONTYPE OGR parameter must be used.

*  The path to the (\*.tab or \*.mif) file is required, and the file 
   extension is needed.

*  The path may be relative to the SHAPEPATH

*  MapInfo files already contain styling information.  This styling 
   information can be used optionally by specifying the 
   STYLEITEM "AUTO" parameter in the LAYER object of the map file.

   .. note::
	    
	    If you use STYLEITEM "AUTO" you must have an empty class in the layer.

OGRINFO Examples
------------------

Using ogrinfo on a single TAB file

::
	
	> ogrinfo elev5_poly.TAB
	Had to open data source read-only.
	INFO: Open of `elev5_poly.TAB'
	using driver `MapInfo File' successful.
	1: elev5_poly (Polygon)

Using ogrinfo to examine the structure of the file/layer

::

	> ogrinfo elev5_poly.TAB elev5_poly
	Had to open data source read-only.
	INFO: Open of `elev5_poly.TAB'
	using driver `MapInfo File' successful.

	Layer name: elev5_poly
