Importing MapInfo File

Function Description

The MapInfo data imported by SuperMap includes three types: *.mif, *.wor, and *.tab. The Data Type is described as follows:

  • MIF format is an intermediate exchange file used by MapInfo for external data exchange. When a user opens a map table with MapInfo and rolls it out in *.mif format, MapInfo generates two files (*.mif and *.mid). The *.mif file stores the table structure of MapInfo and the Spatial Info of the object, including the symbol style, Fill Mode and other style information of the object. The *.mid file, on the other hand, stores the Attributes of each object in the order in which they are recorded.
  • WOR files (*.wor) are MapInfo Workspace File. Workspace files hold information such as tables, windows and window positions, maps, layouts, resource symbols, MapInfo Environment Settings, and so on.
  • TAB file (*.tab) is the table structure file of MapInfo attribute data, which stores information in the form of table. TAB file defines the table structure of Map Properties data.

Function entrance

  • Start tab-> Data Processing-> Data Import.
  • In Workspace Manager-> Datasource Context Menu-> Import Dataset...
  • Tools in Toolbox-> Data Import-> MapInfo: Import TAB, Import MIF, Import WOR.

Operating instructions

  1. On the Data Import dialog, in the toolbar, click the Add File button. Add the *.mif/*.wor/*.tab format file to be imported. See Introduction to Import Data for the adding method.
  2. Target Datasource, Result Dataset, Encode Type, Import Mode, and Parameter Description of Source File Info: in Result Data. See the Data Import public parameter description page.
  3. Result Data
    • Dataset Type: Select the imported Dataset as Simple Dataset or CAD (CAD Dataset). (No setup required to import *.wor data)
      1. CAD CAD: select this option to set the data Import File as CAD Dataset.
      2. Simple Dataset: Select this item to set the data file Import as Simple Dataset, i.e., point, line, surface, text, and attribute data sets.
    • Create Spa tial Index: Check this item to DatasetCreate Spatial Index according to the index type supported by Dataset.
  4. Transformation Parameters
    • Import Attributes: If this parameter is checked, it means the Import Spatial Data will import Attributes at the same time; otherwise, only Spatial Info will be imported without Attributes. (No setup required to import *.wor data)
  5. After setting, click the Import button to import the MapInfo file.
