Image Analysis window: Processing section

The Image Analysis window's Processing section simplifies the experience of applying complex processing and analysis techniques to layers of image and raster data in ArcMap. The tools provide one-click options to apply processes, such as clipping, normalized difference vegetation index (NDVI) creation, mosaicking, and exporting. The tools are responsive to the selected layers in the window and are activated only when the appropriate inputs for the processes are selected. More than one layer can be chosen, and using the tool applies the processing or analysis to each layer creating temporary layers in the table of contents.

The processing is applied to the raster, mosaic dataset, image service, or WCS layers on the fly. The original data remains unaltered, with the results added as new temporary layers to the data frame. If you want to save the dataset in the temporary layer, you need to export the raster dataset or you can save the layer file.

Image Analysis toolbar buttons and their functions

Button	Name	Function
	Clip	Uses the data view extent or a selected polygon graphic or feature to chip out a portion of the image or raster dataset and create a temporary layer.
	Mask	Uses the data view extent or a selected polygon graphic or feature to define an area of NoData and create a temporary layer.
	Composite Bands	Allows you to combine layers to form a temporary multiband layer.
	NDVI	Computes a normalized difference vegetation index (NDVI) from a multispectral image or two selected layers and outputs a temporary layer.
	Colormap To RGB	Converts a color-mapped layer to a three-band (RGB) temporary layer.
	Difference	Computes the change between two layers, using a pixel-over-pixel comparison, and outputs a temporary layer.
	Pan-sharpening	Creates a temporary layer of pan-sharpened multispectral data.
	Orthorectify	Creates a temporary layer of orthorectified data.
	Export	Opens the ArcGIS Export Raster Data dialog box to save the temporary layer as a raster dataset.
	Shaded Relief	Applies a color-shaded relief to a selected elevation raster dataset and outputs a temporary layer.
	Mosaic	Generates a temporary layer by mosaicking two or more layers. The mosaic methods are chosen from the drop-down list.
	Filter	Generates a temporary layer with some type of filter applied, including the capability to sharpen, blur, enhance edges or other kernel-based image enhancements.

Note:

You cannot work with a raster catalog layer using the Image Analysis window.
