• Contour - Opens the Contour Properties Editor to change how the contours appear in the Main Display window. This is an option for the Contour Plan View and Color-Filled Contour Plan View display types.
• Color Table - Shows the active color table and the associated high and low data values in the units of the display. As the mouse pointer is moved over the color bar, the value at a particular color is shown. Right click on the color bar or click on the button that displays the name of the Color Table to make modifications to the color bar. This allows you to open the Color Table Editor, change the range, select other color tables, etc. This is an option for the Contour Plan View, the Color-Filled Contour Plan View, and the Color-Shaded Plan View display types.
• Smoothing - Smooths the grid. There are seven types of smoothing: None, 5-point, 9-point, Gaussian Weighted, Cressman Weighted, Circular Aperture, and Rectangular Aperture. The amount of smoothness can be set for all except the 5 and 9-point smoothers. The higher the amount, the smoother the grid. For the Cressman, Circular and Rectangular aperture smoothing types, the smoothing factor is the radius in grid spacing units.
• Levels - Lists the native grid levels. Click on one level value to reset the plan to that level. The plan level in use is shown in the data's native altitude units. The Levels box is editable. Click in the box, enter a value and hit Enter to set your own value. Additionally, you can click on the arrows to the right of the Levels box to switch levels, or click on the Cycle check box to animate vertically through all available levels. This is an option for the Contour Plan View, the Color-Filled Contour Plan View, and the Color-Shaded Plan View display types.
• Visible Range - Determines what parts of the data is actually shown. Click the button to set the range of data shown. Once the checkbox is checked, the Visible Range will be applied to the data in the Main Display window. This is an option in the Color-Shaded Plan View.
• Texture Quality - Sets the quality of the displayed texture. A higher quality will take longer to render and user more memory. This is an option for the Color-Shaded Plan View display type.
• Shade Colors - Colors every pixel to give a smooth gradation of color. The alternative is coloring an area of pixels corresponding to a single data grid cell with one color. This is an option for the Color-Shaded Plan View display type.
• Mode - Sets the way the texture is displayed. You can select Solid, Mesh, or Points. This is useful for looking at the structure of the underlying data. This is an option for the Color-Shaded Plan View display type.
• Point Size - Sets the size of the points when the Points Mode is selected. This is an option for the Color-Shaded Plan View display type.
