#Define raster code
Performs bitwise, conditional, logical, mathematical, and statistical operation calculations, on a pixel-by-pixel basis.Ĭalculates the Normalized Difference Vegetation Index (NDVI) values using a two-band raster consisting of the red and near-infrared bands.Įnhances the spatial resolution of a multiband image by fusing it with a higher-resolution panchromatic image.Ĭonverts your Python code into a custom raster function.Ĭonverts the pixels of RADARSAT-2 imagery to a true representation of the radar It is added when the data is added to a mosaic dataset using the LAS raster type. It is added when the data is added to a mosaic dataset using the LAS dataset raster type. Inserts or overrides the key metadata of a raster. Generates a grayscale model of a terrain with the sun's relative position taken into account for shading the terrain.ĭefault function required by all rasters in a mosaic dataset if there is no other function.Ĭonverts irregularly gridded point clouds or raster data into square pixels. This can be used to orthorectify rasters based on a sensor definition and a terrain model.Ĭonverts a multiband raster into a grayscale raster. Rectifies an image based on the geodata transformation that is supplied with the raster. Reorders or extracts bands from a raster. The curvature is calculated by computing the second derivative of the surface.Ĭreates pixels in areas where holes exist within your elevation data. 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.ĭisplays the shape or curvature of the slope. Transforms the pixel values to display the raster data as either a grayscale or a red, green, and blue (RGB) image, based on a color map.Ĭonverts a single-band raster with a color map to a three-band (red, green, and blue) raster.Ĭombines rasters to form a multiband raster.Ĭreates a virtual raster with a single pixel value for all its pixels.Įnhances the appearance of raster data (imagery) by modifying the brightness or contrast. This function requires the ArcGIS Spatial Analyst extension to be enabled.Įxtracts or excludes an area in a raster according to a set of extents.Ĭonverts the color model of an image, for example, from either the hue, saturation, and value (HSV) to red, green, and blue (RGB), or vice versa. Performs an arithmetic operation on the bands of a raster dataset.Ĭreates a raster output that divides your raster into two distinct classes.Ĭreates a preprocessed cache dataset at the point in the function chain where it's added for an item in a mosaic dataset.Ĭlassifies a raster dataset based on an Esri Classifier Definition (.
Identifies the downslope direction of the maximum rate of change in value from each cell to its neighbors.ĭefines an attribute table that will be used to symbolize a single-band mosaic dataset. Performs an arithmetic operation between two partially or completely spatially overlapping rasters or a raster and one or more constant values. Statistics functions: ArgMax, ArgMin, ArgMedian, and Duration. Functions Function nameĪdjusts image brightness values (DN) for some The functions are organized within a function chain, allowing you to create various processed products by chaining together multiple functions. These functions are applied to the raster data on the fly as theĭata is accessed and viewed therefore, they can be applied quickly without having to endure the time it would otherwise take to create a processed product on disk.įunctions can be applied to various rasters (or images), including the following: The raster functions allow you to define processing operations that What are the functions used by a raster or mosaic dataset?
