Slope and Aspect Analysis

Figure: TIN Terrain Slope and Aspect Analysis.

• Show All: The default value is Show All ", that is, all the layer models participate in the Slope and Aspect Analysis.
• Area display: After this item is checked, move the mouse to the scene area, and it will change to the editing line state. You can click on the model to draw a polygon area, which means that the model in the polygon area will perform Slope and Aspect Analysis, and no Slope and Aspect Analysis will be performed outside the area.
• Select Region: After checking this item, activate the drop-down box of the Select Region from Dataset "and select the Datasource opened by Current Workspace.
• Display Mode: provides four modes: No Display, Slope, Slope Aspect and Slope Aspect. Click the drop-down box on the right to select.
• Color Scheme: Click the color drop-down box on the right and select the Color Scheme for filling the cache.
• Minimum value of color table: Enter a number to set the elevation intensity value corresponding to the leftmost color of the texture color table. The default value is the minimum value of the elevation intensity value of the model.
• Maximum value of the color table: Enter a number to set the elevation intensity value corresponding to the rightmost color of the texture color table. The default value is the maximum value of the elevation intensity value of the model.
• Minimum Visible Value: Enter a number to set the minimum value of the model elevation intensity value participating in the Slope and Aspect Analysis. The default value is the minimum value of the model elevation intensity value. Models smaller than this value do not undergo Slope and Aspect Analysis.
• Maximum Visible Value: Enter a number to set the maximum value of the model elevation intensity value participating in the Slope and Aspect Analysis. The default value is the maximum value of the model elevation intensity value. Models larger than this value do not undergo Slope and Aspect Analysis.
• Flow: Check this item, and the arrow in the analysis area will have a flow effect.
