Raster and imagery default options

The raster and imagery default options allow you to change settings, which will be applied to all of your imagery and raster datasets. You can access these options from Project tab > Options > Raster and Imagery.

The raster and imagery options consist of the following six categories:

  • Appearance
  • Cache
  • Raster Dataset
  • Mosaic Dataset
  • Perspective Imagery
  • Raster Formats

Appearance

The Appearance options allow you to set rendering defaults for rasters that you add to a view.

The Use band wavelength information when available check box allows ArcGIS Pro to determine which bands you want to display when working with three-band and multispectral datasets. For three-band imagery, the defaults are appropriate. Due to technological advances, more sensors are incorporating additional bands. If you consistently work with a sensor that is not one of the raster products, it may make sense to alter these defaults.

You can select a default color scheme from the drop-down menu instead of the default gray scale color scheme. Click the Reset button to set the default to the gray scale color scheme.

You can use the Enable custom rendering defaults option to set a specific way to display all of your datasets. This is turned off by default because users tend to work with many different kinds of data, from high-resolution imagery to classified raster datasets. It makes sense to enable this if you work with a specific type of dataset.

The background of a raster dataset can be displayed in a specific color or with transparency. This allows you to hide or highlight the background. To display the background value in a specific color, check the check box, and specify the background value and the color. Usually, the background color is set to transparent so that it is hidden.

The NoData color allows you to hide or highlight these values. Typically, the NoData color is set to transparent so that the NoData values are hidden.

Cache

When checked, if an image service has cache generated, it will display the image service cache rather than the image service.

Raster Dataset

Check Use the world file to define the coordinates of the raster if you want to override the dataset's native georeferencing with the world file information.

The Maximum number of values to display option is set to 65,536 by default. This is the maximum number of values you can get with 16-bit data. Increasing this number will enable you to work with datasets that have a greater bit depth without scaling it down to 16 bit; however, this will increase computational effort and lower performance.

The Proxy files location allows you to work around restrictions that system administrators put on data repositories. For example, if you need to build pyramids for an image but only have read permissions to that folder, the pyramids will be built in the proxy location. The proxy location cannot be edited.

Mosaic Dataset

These options control how a mosaic dataset is presented in the Contents pane as follows:

  • Expanding the mosaic dataset will display its component layers, boundary, footprint, and image in the Contents pane.
  • Showing the boundary will display the full extent of the dataset as a polygon on the map.
  • Showing the footprint will show the extent of each raster within the mosaic dataset on the map.
  • Use Build Seamlines to create a smoother looking mosaic dataset when working with images collected at varying times and spatial resolutions. They will be shown as feature classes on the map.
  • Showing the image on the map. Uncheck this box to improve performance if it is not necessary to immediately see your imagery or raster dataset.

Perspective Imagery

You can check the Set focus on the first operational perspective image layer to map check box to automatically work in the perspective view when an appropriate layer is added to a map.

Raster Formats

This table shows all of the raster and imagery formats you can work with.

Note:

Enabling and disabling specific formats is not currently supported. All formats are enabled.
