What are the raster or mosaic dataset functions?

Functions can be applied to the raster data in a mosaic dataset or on the entire mosaic dataset. These functions are applied to the raster data on the fly as the mosaicked image is accessed and viewed.

Functions

Function name	Description
Arithmetic	Performs an arithmetic operation between two partially or completely spatially overlapping rasters or a raster and one or more constant values.
Aspect	Identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors.
Clip	Extracts or excludes an area in a raster according to a set of extents.
Color Model Conversion	Converts the color model of an image. For example, from either the HSV (hue, saturation, and value) to RGB (red, green, and blue) or vice versa.
Colormap	Transforms the pixel values to display the raster data as either a grayscale or a red, green, blue (RGB) image, based on a color map.
Colormap To RGB	Converts a single-band raster with a color map to a three-band (red, green, and blue) raster.
Complex	Computes magnitude from complex values.
Composite Band	Combines rasters to form a multiband raster.
Constant	Creates a virtual raster with a single pixel value for all its pixels.
Convolution	Performs filtering on the pixel values in a raster, which can be used for sharpening an image, blurring an image, detecting edges within an image, or other kernel-based enhancements.
Extract Band	Reorders or extracts bands from a raster.
Geometric	Rectifies an image based on the geodata transform that is supplied with the raster. This can be used to orthorectify rasters based on a sensor definition and a terrain model.
Grayscale	Converts a multiband raster into a grayscale raster.
Hillshade	Generates a grayscale model of a terrain with the sun's relative position taken into account for shading the terrain.
Identity	Default function required by all rasters in a mosaic dataset if there is no other function.
Mask	Creates NoData by defining a range of pixel values. Any values outside the range will be returned as NoData.
NDVI	Calculates the Normalized Vegetation Differential Index (NDVI) values using a two-band raster consisting of the Red and near-infrared bands.
Pan-sharpening	Enhances the spatial resolution of a multiband image by fusing it with a higher-resolution panchromatic image.
Raster Info	Modifies properties of the raster, such as bit depth.
Shaded Relief	Generates a shaded relief from an elevation model and color ramp.
Slope	Calculates the rate of change of elevation for each DEM cell.
Spectral Conversion	Applies a matrix to a multiband image to affect the spectral values of the output. This can be used to convert a false color image to a pseudo color image.
Statistics	Calculates focal statistics for each pixel of an image based on a defined focal neighborhood.
Stretch	Enhances an image by changing properties such as brightness, contrast, and gamma through multiple stretch types.
