If the Dataset attribute panel -- Display Raster Dataset Information displays the information of one or more Raster Datasets, the Properties panel has three module information: Dataset, coordinate system, grid, each panel displays the corresponding information content. The following details the specific content of each type of information:
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 Dataset.
- Table: Displays the name of the Dataset's property sheet.
- Encoding: Displays the Encode Type of the Raster Dataset, that is, the compression Encode Type when the Dataset is stored. For details about the Encode Type of the Dataset, See: Dataset Compression Encode Type .
Dataset Bounds：
- The upper and lower values are the two boundaries along the Y-axis direction (i.e., 'Y ='); the left and right values are the two boundaries along the X-axis direction (i.e., 'X ='). The units of the values are the same as those of the Dataset. You can directly enter the value to modify, and click the Apply button in the lower right corner of the Properties Panel to take effect.
- Copy and Paste: Click the Copy button to Copy CurrentDataset Bounds, or click the Paste button to set the left, bottom, right, and top values of Copy Bounds to the current range.
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 on the Properties panel, and the panel will 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 the Detail Description information of the Raster Dataset projection.
Button below the coordinate system information display areaFunction Description:
- Reset: Click this button to bring up the Projection Settings dialog and reset the coordinate Projection of the Dataset. Please refer to the Projection Settings window for specific setting methods.
- Copy: Click this button to pop up the Copy Coordinate System dialog, where you can copy the Coordinate System information as the Projection of the Current Data set. The system provides three ways to Copy Coordinate System: Copy the source coordinate Projection of Existing data in Current Workspace, Copy the coordinate Projection of the Existing data set in the Current Workspace, and copy the specified Projection Info File locally. The system supports 7 types of Projection Info File, TIFF File (*.TIF), SIT (*.SIT), Erdas Image File (*.IMG), ArcGIS Shapefile (*.SHP), MapInfo Exchange Format (*.MIF), MapInfo TAB File (*.TAB), Projection Info File (*.XML).
- Export/Export Coordinate System: supports importing/exporting Projection Info File (*.xml).
- Transformation: Click this button to pop up the Projection Transformation dialog box to transform the current Projection of the selected Dataset. For the specific setting method, please refer to the Operation Description of Projection Transformation Dialog Box in Projection Transformation .
Grid
Click the Grid node in the Properties panel, and the panel will display the information of the Raster Dataset.
Image Properties：
- Pixel Format: Displays the Pixel Format stored in Raster Data, that is, how many bytes are used to represent each pixel value.
- X Resolution: Displays the resolution in the Raster Dataset X direction.
- Y Resolution: Displays the resolution in the Raster Dataset Y direction.
- Null: Displays the grid value of the pixel without data in the Raster Dataset.
- Rows: Displays the rows of the Raster Dataset pixel array.
- Columns: Displays the number of columns of the Raster Dataset pixel array.
- Color Scheme: is used to set the display color of pixels in the selected Raster Dataset. This setting is to modify the color table of the Raster Dataset itself. If you only want to modify the color table of the Raster Dataset in the Current Map, See Sets the color table for the Raster Layer . The set Color Scheme can be seen in the newly opened Map.
- Grid block: displays the size of the current Raster Dataset grid block. For example, when it is displayed as 256 * 256, it means that every 256 * 256 pixels will be stored as a grid block. During Data Processing, a grid block will be processed together.
Extreme:
- Max: Displays the maximum value of the grid value in the Raster Dataset.
- Min: Displays the minimum value of the grid value in the Raster Dataset.
Statistic Infomation
Pixel information of Current Data will be displayed in the Statistic Infomation list, including maximum value, minimum value, variance, mode, etc. Note: In order to ensure the correct display of Statistic Infomation of Current Data, it is recommended that the user perform statistical calculation on the data through the Calculate button at the bottom right when viewing.
Other:
- Pyramid: Displays whether the Raster Dataset has been created Pyramid.
- Histogram: Displays whether the Raster Dataset has been created. If it has been created, you can view it through the Browse button on the right. If it has not been created, you can create the Histogram through the Create button on the right.
- Visible Bounds: Used to set the Visible Bounds: of the Raster Dataset in the map. For the selected Raster Dataset Settings Visible Bounds:, the Raster Dataset will display only the information within the set range, and the rest will be invisible.
Click the Settings button on the right, and the Set Visible Bounds dialog box will pop up. You can use a Region Dataset of Current Works pace as the Visible Bounds of the selected Raster Dataset:; You can also click the button on the right of Filter Expression to pop up the SQL Expression dialog box. Set the Filter Expression in the dialog box to control the Visible Bounds of Raster Dataset. Please refer to the SQL Statement Query for details.
Click the Reset button to reset the Dataset Visible Bounds: to the full display of Dataset.
