Image Export

Instructions for Use

Performs band combination, format conversion, and coordinate system processing on input image files to achieve standardization of data format.

Function Entry

  • Toolbox->Imagery->Basic Tools->Image Export.
  • Start Tab->Common Imagery Tools Group->Image Export.

Parameter Description

Parameter Name Parameter Interpretation Parameter Type
Image File List

Use Image File List to manage image files with Add Image, Select All, Select Reverse, and Delete functions.

  • Add Image: Supports adding images for bit-depth conversion via four methods: add file, add folder, add list, and add mosaic dataset.
    • Add File: Select specific image files from the local directory as images to be checked. Supported formats include *.tiff, *.tif, *.img, *.pix.
    • Add Folder: Select a folder from the local directory to automatically retrieve all images (formats: *.tiff, *.tif, *.img, *.pix) within that folder and its subfolders as images to be checked.
    • Add List: Select a manifest file (*.csv) from the local directory to retrieve images to be checked based on the image names and path information in the manifest file.
    • Add Mosaic Data: Select a dataset from an open data source in the current workspace as the image to be checked.
  • Select All: Select all records in the list.
  • Select Reverse: Invert the selection of all records in the list.
  • Delete: Delete the selected records from the list.
DatasetImage
Export Directory Set the storage path for the result image. String
File Type Set the storage type of the result image. Options include Not Set, Tiff/GeoTIFF, Erdas Image, and PCIDSK. Default is Tiff/GeoTIFF. Selecting Not Set means outputting with the original storage type of the image. FileType
Compression Method Set the compression method for the output image. Available only when the output format is Tiff/GeoTIFF. Default is NONE. CompressMethod
Resolution Type

Set the resolution for image export. Provides two methods: original resolution and fixed value.

  • Original Resolution: Output with the original resolution of the image.
  • Fixed Value: Output the result image based on the specified resolution value.
OrthoRatioType
Resolution Required when Resolution Type is set to fixed value. Output the result image based on the specified resolution value. Double
Resampling Method Set the resampling method after image export. Options include Nearest, Bilinear, and Cubic. Default is Nearest. For more method details, refer to Resampling Method. ResampleMethod
Index Set the index of the output image, corresponding to the sequence number and band value. Boolean
Coordinate System Conversion

Specify whether to convert the coordinate system of the input image before output.

  • Selected: Convert and output based on the set coordinate system.
  • Not Selected: Output with the original image coordinate system.
Boolean
Conversion Method

Required after specifying coordinate system conversion.

Set the method used during projection, generally categorized into three-parameter conversion method and seven-parameter conversion method. For more method details, refer to Reference System Conversion Method Description.

CoordSysTransMethod
Target Coordinate System

Required after specifying coordinate system conversion.

Provides three setting methods. After setting the target projection, the name and details of the target coordinate system will be displayed.

  • Reset Coordinate System: Click the Reset Coordinate System button, select More from the dropdown menu, and a projection settings dialog will pop up. Select the target coordinate system in the dialog. For more operations, refer to Projection Settings.
  • Copy Coordinate System: After clicking the Copy Coordinate System button, choose to copy from a data source or from a dataset in the pop-up dialog:
    • From Data Source: Click the combo box drop-down button, select a data source, and set its coordinate system as the target coordinate system.
    • From Dataset: Click the combo box drop-down button, select a dataset, and set its coordinate system as the target coordinate system.
  • Import Coordinate System: Click the Import Coordinate System... button, and in the pop-up Select dialog, choose and import a projection info file. Supports importing Shapefile projection info files (*.shp;*.prj), MapInfo Exchange Format (*.mif), MapInfo TAB File (*.tab), image format projection info files (*.tif;*.img;*.sit), and projection info files (*.xml).
