Import Image Data

Function Description

Application supports importing multiple image formats, such as IMG, TIF, BMP, JPG, GIF, SIT (obsolete), etc.

Function entrance

  • Start tab-> Data Processing-> Data Import or Drop-down Button.
  • In Workspace Manager-> Datasource Context Menu-> Import Dataset...
  • Tools in Toolbox-> Data Import-> Image Bitmap File.

Operating instructions

Here's how to import IMG and TIF files.

  1. On the Data Import dialog, Target Datasource, Result Dataset, Encode Type, Import Mode, And the Parameter Description of Source File Info:. See the Data Import Public Parameter Description page.
  2. Result:
    • Dataset Type: Sets the type of Import Data. The Result Type for importing Raster Data has two options for the user to select: Image Dataset and Raster Dataset. If Image Dataset is selected, the data Import File will be Image Dataset; if Raster Dataset is selected, the data Import File will be GRID Dataset.
  3. Transformation Parameters：
    • Band Import Mode: Used to set the band import mode of Image Data when importing multi-band Image Data, such as Erdas Image File (*.img) and TIFF File (*.tif). The system provides Multi-band and Single Bands.
      1. Multiband: Import multiband Data into a multiband Dataset. In the properties window of the multi-band Dataset, locate the Image Properties item to view its band table information.
      2. Single Bands: Multi-band Data Import as a single band Dataset.
    • Create Image Pyramid: Select the check box to correct the Import DataCreate Image Pyramid when importing Image Data.
    • Coordinate Reference File: When importing Image Files (valid for TIF files only), you can import *. Tfw Coordinate Reference File. For an introduction to the Coordinate Reference File, see Image Geography Coordinate Reference File.
  4. After setting the above parameters, click the Import button in the dialog box to specify Data Import as Image Data.
Caution:
  • If importing single-band Raster Data, the import mode: None and Append have the same effect, that is, if the imported data has a name conflict with the Existing Data set, the imported data will automatically modify the name and be imported.
  • When importing RAW Image Files, the Result Type can only be imported as an Image Dataset. Selection between Image Dataset and Grid Dataset is not supported.
    • When
  • importing data in the format of *.img, *.tif, or *.tiff, the imported Result DatasetProjected Coordinate System is consistent with the projection of the source file; When importing data in the format of *.bmp, *.png, *.jpg, or *.gif, the Projected Coordinate System of the Result Dataset is the same as the Datasource projection.
  • Because Image Data in IMG format does not support SphereMercator Projection Type, the Projection will be lost when the Data Export of the Projection Type is IMG. It is recommended that the user reset the projection when using it again.
