In the data list of the Data Import dialog box, the parameters displayed on the right vary depending on the selected files. When multiple files are selected, the configurable parameters also differ.

• When multiple vector datasets and raster datasets are selected simultaneously in the list box, the parameters area displays common parameters for importing datasets.
• For different formats of vector data or raster data, the configurable parameters in the Vector File Parameters or Raster File Parameters area may also vary.

Common Parameters

• Target Datasource: Select the target datasource for storing imported files.
  • If a non-read-only datasource is selected in the workspace before executing data import, the selected datasource will be displayed here. When multiple non-read-only datasources are selected, the first one will be shown.
  • If no datasource is selected in the workspace before executing data import, the first non-read-only datasource in the datasource collection will be displayed.
  • If no non-read-only datasource exists in the workspace, this field will be empty.
• Result Dataset: Name of the new dataset after original data import.
• Import Mode: The application provides three import modes: None, Overwrite, and Append.
  • None: If name conflicts exist between imported data and existing datasets, the imported data will be automatically renamed and imported.
  • Overwrite: If name conflicts exist, the imported data will overwrite existing datasets with the same name.
  • Append: If name conflicts exist, the imported data will be appended to existing datasets with the same name. The condition for appending is that the two datasets must have identical types and structures; otherwise, the import will fail, and the State property of the file in the list box will show Failed. For detailed information about dataset appending, see Dataset Append.
    Notes:

    • Import modes yield slightly different results when importing vector and raster data. Specifically, Append and Overwrite modes are applicable only when datasets with the same name exist. Please use them appropriately during actual operations. 
• Encode Type: Specifies whether to save data using compression to save disk space. The default is Uncoded (no compression). For more details about dataset encoding types, see: Dataset Compression Encode Type.
  • For different dataset types, the system automatically determines suitable encode types and displays them in the dropdown menu.
  • For image and raster datasets during import, the system determines appropriate encode types based on their pixel formats. If the selected encode type conflicts with the pixel format, the system will automatically adjust it to a compatible encode type. The table below shows valid encode types for different pixel formats of image and raster datasets.

• Source File Info:
  • Source File Path: Displays the path of the source data to be imported, allowing users to copy paths and inspect source data.
  • Source File Charset: Sets the charset type of the source data. For supported charset lists, see Charset List.
  • Properties: Click the Properties button to view source file attributes, including general information, security settings, and detailed properties.

Notes:

• When multiple raster or vector files are selected in the list box, the file parameters area in Data Import displays parameters based on the last selected file format.
• When both raster and vector data are selected, the file parameters area displays only common parameters.
• When importing single-band raster data, the None and Append modes have the same effect: if name conflicts exist, the imported data will be automatically renamed and imported.
• When importing RAW image files, the result type can only be imported as Image datasets. Switching between Image and Grid datasets is not supported.
