# MapInfo

## 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.
