Import MapGIS Data

Feature Description

This function is used to import MapGIS plain text format data. MapGIS plain text format data consists of ASCII-encoded files with a structure containing two parts: file header and data area. In the MapGIS file system, project files (with *.MPJ extension) typically include point files (*.WT), line files (*.WL), polygon files (*.WP), and network files (*.WN).

Prior to import, MapGIS graphic files must be converted to MapGIS exchange file format (plain text format). After conversion, the four file types will have the following extensions: point plain text files (*.wat), line plain text files (*.wal), polygon plain text files (*.wap), and network plain text files (*.wan).

Additionally, you need to convert the color index table file to plain text format (with *.wat extension) in the MapGIS platform. Note: This *.wat file shares the same format as point plain text files but represents different content.

Feature Entry

  • Start Tab -> Data Processing -> Data Import -> Vector Group -> MapGIS.
  • Workspace Manager -> Datasource Context Menu -> Import Dataset....
  • Toolbox -> Data Import -> MapGIS Tools: Import WAT, Import WAL, Import WAP, Import WAN.

Steps

  1. In the Data Import dialog box, click the Add File button on the toolbar to add *.wat, *.wan, *.wal, or *.wap format files. For adding methods, refer to Import Data.
  2. For parameter descriptions of Target Datasource, Result Dataset, Encode Type, Import Mode in Result Data, and Source File Info, see Common Parameters for Data Import.
  3. Result Data
    • Dataset Type: Select either Simple Dataset or CAD Dataset for the imported data.
      • CAD: Imports files as CAD datasets.
      • Simple Dataset: Imports data files as simple datasets (point, line, polygon, text, or attribute datasets).
    • Create Spatial Index: Check this option to create spatial indexes for datasets according to supported index types.
  4. Transformation Parameters
    • Color Index File: Specify the color index table file path (*.wat) for MapGIS data import. Default uses the built-in MapGISColor.wat file.
  5. Click the Import button to execute the import operation after completing settings.
