Как из Mapinfo извлечь геоданные?

MIF/MID is a file standard used by MapInfo, a desktop mapping system. Autodesk Map supports MapInfo up to version 7 MIF/MID files.
MapInfo MIF/MID format stores both geometry and attributes (data) for features, and is a set of two physical files that work together:
.mif ? Vector geometric data. A single .mif file can contain many different types of geometry.
.mid? Attributes for the geometric data.
For specific information on MapInfo MIF/MID format, read the sections below. For general information on using the Import or Export commands, see Overview of Importing and Overview of Exporting.
Importing
By default, Autodesk Map considers MapInfo MIF/MID a multi-select, file-based format, that is, you select one or more individual .mif files during a single import process. If you want to change the default so that Autodesk Map considers MIF/MID a folder-based format (all files in the folder are included in the import) or a single-select format (only one file can be selected for import), you can modify the settings in the mapimport.ini file. For more information, see Customizing the .ini File.
When you import MapInfo MIF/MID files, it is important that you have both the .mif and .mid files together in the same folder.
Symbol types are similar to Autodesk Map point objects. You cannot import MIF/MID symbol types directly. However, if you store the symbol type information in a column in a MID file, you can map each symbol type to a block in the current Autodesk Map drawing. To do this, you need to prepare the MIF file by putting the name of the symbol type into a field in the database. Prepare the Autodesk Map drawing by creating similar symbols as blocks in the Autodesk Map drawing. Then, during import, perform a point-block mapping and select the check box to get the block name from data and select the symbol type field you created.
In MapInfo, polygons are represented as closed areas. When you import polygons, the polygons appear as polygons in Autodesk Map unless you select the Import Polygons As Closed Polylines check box in the Import dialog box.
By default, object colors are imported to their closest ACI (AutoCAD Color Index) color. If you want to import object colors using RGB (True Color), you must edit the mapimport.ini file. For more information, see Customizing the .ini File.
If you want to change the default text justification setting for MIF/MID, you must edit the mapforeignfileproperties.ini file. Use the [MIF_Justification] section to set justification for MIF. Allowed MIF Justifications are left, center, and right. For more information, see Customizing the .ini File.
Driver Options
MapInfo MIF/MID has no import driver options.
Exporting
The MIF/MID format does not support ellipses with an angled bounding box (i.e, ellipses whose axes are at an angle to the X and Y axes), so when you export such ellipses from Autodesk Map to MIF/MID, they are segmented. For information about how to change the settings Autodesk Map uses for segmentation, see Customizing the .ini File.
