To modify the image display using Unique Values symbology, complete the following steps: This display type is often used with thematic data such as land cover or risk zones. If the raster attribute table has red, green, and blue values specified in respective fields, the dataset will display using those colors by default. You can base the unique values rendering on one or more attribute fields in the dataset. This display option is supported for single-band imagery layers that were published with a raster attribute table. Rendering your imagery using unique values is useful for displaying thematic or categorical data. Click Apply to apply the image display options to the layer, click Reset to return to the default display options, or click Close to close the Image Display tab without saving your choices.Optionally, if your imagery layer is a single-band image or raster, select a color ramp from the Color Ramp drop-down menu.Use the Gamma slider to modify the gamma value, which stretches the middle values in an image but keeps the extreme high and low values constant.

This option is always turned on if the imagery layer does not have global statistics.

Check the Dynamic range adjustment box to perform the selected stretch operation while limiting the range of values to what is currently in the display window.

Optionally, if Stretch Type is set to an option other than None, do one or both of the following:.

Use the two textīoxes to edit the top and bottom percentages.

Percent Clip-Set a range of values to display, and exclude the highest and lowest pixel values from the stretch.

Standard Deviation-Display values between a.

These are available only when the Dynamic range adjustment check box is cleared. Edit the values in the statistics table to make additional changes as needed.

Minimum and Maximum-Display the entire range of values in your.

None-No additional image enhancements will be performed.

To modify the image display using RGB composite symbology, complete the following steps: You can also use other combinations to highlight green vegetation, water, or urban areas. For example, you can use a natural color composite where the red, green, and blue channels are populated with the red, green, and blue sensor bands to render the image as you would see it naturally. Rendering imagery data using the red, green, and blue (RGB) color composite allows you to use information from multiple bands in your multiband imagery to highlight specific features in the imagery. When modifying display settings, the rendering and symbology options available to you in the map depend on the input data.

In these cases, you can select from one of the predefined renderers, or you can choose the User Defined Renderer in the image display options to provide your own settings for display. Alternatively, the Classify renderer allows you to group ranges of pixel values into classes and assign colors to the individual classes.ĪrcGIS Enterprise image services are sometimes published with processing templates, which appear as predefined renderers in the map. For example, the Stretch renderer uses the histogram of pixel values in a single-band raster to enhance the display of continuous data. Different display options are called renderers. The options for displaying imagery layers depend on the type of raster or imagery data contained in the layer and the source of the layer. To change the display settings, you can modify the image display, the image display order, or the image quality. When you add an imagery layer to a map, the map initially uses theĭefault display settings of the imagery layer. You can modify the display settings for map image layers, ArcGIS Server image services, and hosted imagery layers. As the author of a map, you decide how the imagery in the map is presented. Using Map Viewer Classic, you can modify the display of your It will be available in a future release of Map Viewer. This functionality is currently only supported in Map Viewer Classic.
