MapInfo TAB "table" format consists of multiple files, usually five files, referenced by a controlling .tab file. TAB format can result in drawings, labels, and raster images.
To import from TAB format:
Choose File-Import from the main menu.
In the Import dialog browse to the location of the file and double-click on the .tab file desired.
A table and a drawing will be created, with possibly a map and labels as well. Some .tab ensembles will create an image and the image's table.
Importing the sample file shown in the dialog above results in a drawing and its table as well as a labels component for the drawing and a map.
The drawing shows property parcels as area objects.
In the illustration above we have used Style to format the drawing.
See the Example: Import Multiple MapInfo TAB Images topic for an example importing multiple images from TAB format files.
On import of a MapInfo MIF or TAB file, Manifold will translate MapInfo logical data type columns into Manifold boolean data type. Exporting a Manifold drawing to MIF will export Manifold boolean columns into MapInfo logical data type columns.
MapInfo MIF and TAB do not store the names of datums within the projection information stored in the file; instead, the numeric parameters for the datum are saved. When Manifold scans such a file the system will examine these numeric parameters to find a named datum that is a match.
In some cases, more than one datum may use the same numeric parameters. For example, there are many national datums that are mathematically identical to some generically named datums. When several datums match the given numeric parameters, Manifold will choose a neutrally named datum in preference to a name that uses a specific country name.
TAB files will often import with correct projection information but might not do so depending on the vintage of the TAB file. Be ready to gather any notes or metadata from the source of the TAB files that may specify the projection in use. If need be, immediately launch Assign Initial Coordinate System in the Component pane to specify the correct initial projection for the imported components
