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
- 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.
- 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.
- Result Data
- Dataset Type: Select the imported Dataset as Simple Dataset or CAD (CAD Dataset). (No setup required to import *.wor data)
- CAD CAD: select this option to set the data Import File as CAD Dataset.
- 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.
- Dataset Type: Select the imported Dataset as Simple Dataset or CAD (CAD Dataset). (No setup required to import *.wor data)
- 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)
- After setting, click the Import button to import the MapInfo file.
