The Properties panel of an image dataset contains three modules: Dataset, Coordinate System, and Image Information. The following sections detail each module:

Dataset

Click Dataset in the Properties panel to view attributes of the selected image dataset. Parameter descriptions are as follows:

• Basic Info:
  • Name: Displays the name of the image dataset.
  • File Path: Shows the storage path of the image dataset when opened via file database.
  • Size: Displays the file size when opened via file database.
  • Type: Indicates the dataset type.
  • Table Name: For database datasources, shows the corresponding table name in the database. For file databases, displays the dataset properties table name.
  • Encoding: Shows the compression encoding type used for dataset storage. For details, see: Encoding Type List for Dataset Storage.
• Dataset Bounds:
  • The upper and lower values represent boundaries along the Y-axis ("Y="), while the left and right values represent boundaries along the X-axis ("X="). Units match the dataset's coordinate system. Modify values directly and click Apply to confirm changes.
    Note:

    If the original image dataset has no bounds, the right and top values represent (resolution × number of columns) and (resolution × number of rows) respectively.

  • Copy and Paste: Click Copy to copy current bounds, or Paste to apply copied left/bottom/right/top values to current bounds.
• Dataset Description: Shows editable description of the image dataset.

Coordinate System

Click Coordinate System in the Properties panel to view coordinate system information of the selected image dataset:

• Coordinate System: Displays the coordinate system of the image dataset.
• Geographic Unit: Shows the distance unit of the dataset.
• Coordinate System Info: Provides detailed projection description.

Button functions above the coordinate system information area:

• Reset: Opens the Projection Settings dialog to reconfigure projection. For details, see Projection Settings window.
• Copy: Opens Copy Coordinate System dialog to copy coordinate systems from: existing datasources/datasets in current workspace, or local projection info files (*.TIF, *.SIT, *.IMG, *.SHP, *.MIF, *.TAB, *.XML).
• Export: Exports dataset projection as *.xml file.
• Import: Imports coordinate system from *.xml file.
• Convert: Opens Project dialog for projection conversion. See Project for steps.

Image

Click Image in the Properties panel to view image properties:

Image Information:

• Number of Bands: Displays band count for multiband datasets.
• X Resolution: Spatial resolution along X-axis.
• Y Resolution: Spatial resolution along Y-axis.
• Raster Tiling: Shows raster block size (e.g., 256×256 pixels per block) for optimized processing.
• No-Value: Represents meaningless pixel values using RGB decimal integers. Adjustable in layer properties (e.g., RGB mode displays 96555 as (1,21,43)).

• Number of Rows: Pixel array row count.
• Number of Columns: Pixel array column count.

Image Metadata:

Available when opening remote sensing files with RPC info (*.xml, *.txt, *.tif, *.tiff):

• Sensor Name: e.g., GF-2, SuperView-1.
• Product ID: Unique identifier for the image file.
• Acquisition Date: e.g., 2017-10-21.
• Cloud Cover (%): 0% (clear) to 100% (fully covered).
• Solar Azimuth (°): Angle between sun-ground projection and geographic meridian at image center.
• Solar Elevation (°): Angle between sun direction and horizontal plane at image center.
• Sensor Azimuth (°): Angle between sensor-ground projection and meridian.
• Sensor Elevation (°): Angle between sensor direction and horizontal plane.

Band Info:

• Index: Band index (0-based).
• Name: Band identifier.
• Pixel Format: Bit depth per pixel (e.g., 8-bit, 16-bit).
• Min: Minimum pixel value in the band.
• Max: Maximum pixel value in the band.
• Radiance Gain: Conversion coefficient from DN to radiance (for RPC-enabled files).
• Radiance Bias: Offset value for radiance conversion.
• Solar Irradiance: Radiant flux density (W/m²) reaching Earth's surface (RPC-enabled files).

For single-band images (e.g., Landsat 8), combine bands for multiband display:

1. Add Bands: Click Add to select datasets in Select dialog.
   • Band 432 combination produces true-color imagery for land cover identification (Fig. 2).
   • Band 543 combination creates standard false-color imagery for vegetation/water analysis (Fig. 3).
2. Delete Bands: Select a band and click Delete to remove.

Statistics Information:

• Pre-calculated statistics show per-band pixel details.
• If no statistics exist, a prompt appears. Use the Statistics button to generate.

Others:

• Pyramids: Indicates whether pyramids are built.
• Histogram: Check existing histograms via Browse, or create new ones with Create.
• Visible Bounds: Limits raster display to specified geographic extent.

  Click Settings to define bounds using a region dataset or SQL expression (see SQL Query).

  Click Reset to restore full dataset display.
