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 the Project tab > Options > Raster and Imagery.
Determine which bands you want to display when working with three-band and multispectral datasets. For three-band imagery, the defaults should be fine. Because of technological advances in the ability to sense at shorter wave lengths, more sensors are incorporating an additional blue band. Some sensors will completely leave the blue band out due to a low signal-to-noise ratio. If you are consistently working with a sensor that is not one of the Raster Products, it may make sense to alter these defaults.
Select a default color scheme from the drop-down menu instead of the default gray scale color scheme.
Enable custom rendering defaults if you want 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 would make sense to enable this if you are only working 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. If you want to display the background value in a specific color, check the check box, then 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. Usually, the NoData color is set to transparent so that the NoData values are hidden.
When checked, if an image service has cache generated, it will display it rather than the image service.
Use the world file to define the coordinates of a dataset if you want to override the dataset's native georeferencing.
The maximum number of values to display 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.
Set up a proxy file to work around restrictions that system administrators put on data repositories. If you need to build pyramids on an image, but only have read permissions to that folder, the pyramids will be built in the proxy location.
These options control how a Mosaic Dataset is presented in the Contents pane and on the map.
- Expanding the mosaic dataset will display its component layers, the boundary, footprint, and the 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.
- 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.
The Show function parameters checkbox is on by default. This means that when you click on a raster function in the Processing pane, it will expose the parameters of the function. If you disable this checkbox, when you click on a function it will immediately apply it to the layer based on the default settings.
This table shows all of the raster and imagery formats that you can work with.
Enabling and disabling specific formats is not currently supported. All formats are enabled.
