Raster Dataset Attribute Panel

If the Dataset Attribute Panel displays information for one or more Raster Datasets, the Properties panel includes three sections: Dataset, Coordinate System, and Raster. Each section displays corresponding information. The details of each type of information are described below:

Dataset Information

Click the Dataset option in the Properties panel to display the attributes of the Raster Dataset.

Basic Info:

  • Dataset Name: Displays the name of the Raster Dataset.
  • Dataset Type: Displays the type of the dataset.
  • Table: Displays the name of the attribute table for the dataset.
  • Encoding: Displays the encode type of the Raster Dataset, which is the compression encode type used during dataset storage. For details on dataset encode types, see: Dataset Compression Encode Type.

Dataset Bounds:

  • The top and bottom values represent the two boundaries along the Y-axis (i.e., 'Y='), while the left and right values represent the two boundaries along the X-axis (i.e., 'X='). The unit of the values is the same as that of the dataset. You can directly input values to modify them, and click the Apply button at the bottom right of the properties panel to apply the changes.
  • Copy and Paste: Click the Copy button to copy the current dataset bounds. You can also click the Paste button to set the copied left, bottom, right, and top values to the current bounds.

Dataset Description:

  • Dataset Description: Displays the description of the Raster Dataset. Users can edit the description of the dataset.

Coordinate System

Click the Coordinate System node in the Properties panel to display the coordinate system information of the Raster Dataset separately.

  • Coordinate System: Displays the coordinate system information of the Raster Dataset.
  • Unit: Displays the distance unit of the Raster Dataset.
  • Coordinate System Information: Displays detailed description information of the Raster Dataset projection.

Function description of buttons below the coordinate system information display area:

  • Reset: Click this button to open the Projection Settings dialog box, where you can reset the coordinate projection of the dataset. For specific setup methods, see the Projection Settings window.
  • Copy: Click this button to open the Copy Coordinate System dialog box, where you can copy coordinate system information to use as the projection for the current dataset. The system provides three ways to copy the coordinate system: copying the coordinate projection from an existing data source in the current workspace, copying the coordinate projection from an existing dataset in the current workspace, or copying a specified projection info file from local storage. The system supports seven types of projection info files: TIFF File (*.TIF), SIT (*.SIT), Erdas Image File (*.IMG), ArcGIS Shapefile (*.SHP), MapInfo Exchange Format (*.MIF), MapInfo TAB File (*.TAB), and Projection Info File (*.XML).
  • Export Coordinate System: Supports importing/exporting projection info files (*.xml).
  • Convert: Click this button to open the Project dialog box, where you can convert the current projection of the selected dataset. For specific setup methods, see the operation instructions for the project dialog in Project.

Raster

Click the Raster node in the Properties panel to display information about the Raster Dataset.

Image Properties:

  • Pixel Format: Displays the pixel format used for storing raster data, indicating how many bytes represent each pixel value.
  • X Resolution: Displays the resolution of the Raster Dataset in the X direction.
  • Y Resolution: Displays the resolution of the Raster Dataset in the Y direction.
  • NoData Value: Displays the raster value for cells in the Raster Dataset that contain no data.
  • Number of Rows: Displays the number of rows in the cell array of the Raster Dataset.
  • Number of Columns: Displays the number of columns in the cell array of the Raster Dataset.
  • Color: Used to set the display color for cells in the selected Raster Dataset. This setting modifies the color table of the Raster Dataset itself. If you only want to modify the color table for the Raster Dataset in the current map, see Set Color Table for Raster Layer. The set color can be viewed in newly opened maps.
  • Raster Tiling: Displays the size of the current Raster Dataset's raster tiles. For example, if it shows 256*256, it means each 256*256 pixel block is stored as a raster tile and processed together during data processing.

Extreme Values:

  • Maximum Value: Displays the maximum raster value in the Raster Dataset.
  • Minimum Value: Displays the minimum raster value in the Raster Dataset.

Statistics Information

The statistics information list displays cell information of the current data, including maximum value, minimum value, variance, mode, etc. Note: To ensure correct display of statistics information for the current data, it is recommended to perform statistical calculations using the Calculate button at the bottom right before viewing.

Other:

  • Pyramid: Indicates whether pyramids have been built for the Raster Dataset.
  • Histogram: Indicates whether a histogram has been created for the Raster Dataset. If created, you can view it using the Browse button on the right. If not created, you can create it using the Create button on the right.
  • Visible Bounds: Used to set the visible bounds of the Raster Dataset in the map. After setting the visible bounds for the selected Raster Dataset, it will only display information within the set range, with the rest being invisible.

    Click the Settings button on the right to open the Set Visible Bounds dialog box. You can use a region dataset from the current workspace as the visible bounds for the selected Raster Dataset. Alternatively, click the button next to filter expression to open the SQL Expression dialog box, where you can set the filter expression to control the visible bounds of the Raster Dataset. For details, see SQL Expression.

    Click the Reset button to reset the dataset visible bounds to fully display the dataset.

Notes:

The project button in the Raster Dataset properties dialog is grayed out. Raster Datasets only support projection through the Project function in the Start tab Data group or the context menu. For specific operation methods, see Project.
