Data Import Public Parameters

In the data list of the Data Import dialog box, selecting different files displays different parameters on the right. When multiple files are selected, the configurable parameters are also inconsistent.

  • If the user selects multiple vector datasets and raster datasets simultaneously in the list box, the parameters area displays the public parameters for importing datasets.
  • For different formats of vector data or raster data, the parameters that can be set in the vector file parameters or raster file parameters areas may also vary.

Public Parameters

  • Target Datasource: Select the datasource where the imported files will be stored.
    • If a non-read-only datasource is selected in the workspace before performing data import, the selected datasource will be displayed here. If multiple non-read-only datasources are selected, the first one will be displayed.
    • If no datasource is selected in the workspace before performing data import, the first non-read-only datasource in the datasource collection will be displayed.
    • If there are no non-read-only datasources in the workspace, it will be displayed as empty.
  • Result Dataset: The name of the new dataset after the original data import.
  • Import Mode: The application provides three import modes for users to choose from: None, Overwrite, and Append.
    • None: If there is a name conflict between the imported data and existing datasets, the imported data will be automatically renamed and imported.
    • Overwrite: If there is a name conflict between the imported data and existing datasets, the imported data will overwrite the existing dataset with the same name.
    • Append: If there is a name conflict between the imported data and existing datasets, the imported data will be appended to the existing dataset with the same name, provided that the two datasets are identical in type and structure. Otherwise, it will not be imported, and the State attribute of the file in the list box will be Failed. For detailed instructions on dataset appending, please refer to Dataset Append.
      Notes:
      • The results of the import mode differ slightly when importing vector and raster data. It is particularly emphasized that the Append and Overwrite modes are used when datasets with the same name exist. In actual operations, please use them accordingly. 
  • Encode Type: Specifies whether to save data using compression, which can save disk space. The system defaults to Uncoded, meaning no compression is used. For more information on dataset encode type, please refer to: Dataset Compression Encode Type.
    • For different types of datasets, the system automatically determines the appropriate encode type and displays it in the dropdown menu.
    • For image and raster datasets, when importing datasets, the system will determine a reasonable encode type based on their pixel format. If the encode type selected by the user does not match the pixel format reasonably, the system will automatically correct it to a reasonable encode type and import it into the current datasource. The table below lists the reasonable encode types corresponding to different pixel formats for image and raster datasets.

  • Source File Info:
    • Source File Path: The path of the source data to be imported, allowing users to copy the path and view the source data.
    • Source File Charset: Used to set the character set type of the source data. For the list of character sets supported by the application, please refer to Charset List.
    • Properties: Click the Properties button to view the attributes of the source file, enabling users to see general, security, details, and other properties of the source file.
Notes:
  • If the user selects multiple raster files or vector files simultaneously in the list box, the file parameters area in the Data Import region will display parameter items based on the format of the last selected data.
  • If the user selects both raster data and vector data simultaneously in the list box, the file parameters area in the Data Import region will only display public parameters.
  • When importing single-band raster data, the import modes None and Append have the same effect: if there is a name conflict between the imported data and existing datasets, the imported data will be automatically renamed and imported.
  • When importing RAW image files, the result type can only be imported as an Image dataset. It is not supported to choose between Image dataset and Grid dataset.
