Raster file9/2/2023 For more information, see the NDVI function.Īpplies the NDVI function on the input image, and uses a color map or color ramp to display the result. The Normalized Difference Vegetation Index (NDVI) is a standardized index that uses the contrast of the characteristics of two bands from a multispectral raster dataset-the chlorophyll pigment absorptions in the red band and the high reflectivity of plant materials in the near-infrared (NIR) band. Generates an image displaying greenness (relative biomass). For more information, see the LandTrendr Analysis raster function. For more information, see the Kernel Density raster function.Įvaluates changes in pixel values over time using the Landsat-based detection of trends in disturbance and recovery (LandTrendr) method and generates a change analysis raster containing the model results. For more information, see the Heat Index raster function.Ĭalculates a magnitude-per-unit area from point or polyline features using a kernel function to fit a smoothly tapered surface to each point or polyline. For more information, see the Generate Trend raster function.Ĭalculates apparent temperature based on ambient temperature and relative humidity. Generates a raster containing pixel change information using the output change analysis raster from the Analyze Changes Using CCDC tool.įor more information, see the Detect Change Using Change Analysis raster function.Įstimates the trend for each pixel along a dimension for a given variable in a multidimensional raster. For more information, see the Compute Change raster function. For more information, see the Binary Thresholding raster function.Įvaluates changes in pixel values over time using the Continuous Change Detection and Classification (CCDC) method and generates a multidimensional raster containing the model results.įor more information, see the CCDC Analysis raster function.Ĭomputes the differences between two raster datasets. Analysisĭivides a raster into two distinct classes using the Otsu method, which distinguishes between background and foreground in imagery by creating two classes with minimal intraclass variance. The raster functions available in Map Viewer Classic are listed below. You can also save the raster function template as an item in My Contents, where you can share it throughout your organization or with external users. When you are finished, you can close the raster function editor window to run the template in your map. Double-click a function to modify the properties. The available raster functions are listed in the left pane select your raster function and click Add Function to add it to the raster function template. In the Raster Analysis pane, click the Raster Function Editor button to open the Raster Function Template window. You can use raster functions and build your own custom raster function template chains in the Raster Function Editor. To see the raster functions provided in ArcGIS, filter the list to view the System functions. Click the Browse Raster Function Templates button to access the raster functions and raster function templates available in your content or your organization. Click Raster Analysis to open the Raster Analysis pane. To access the raster functions, open a map, click Analysis, which opens the Perform Analysis pane. The table below lists the raster functions available for raster analysis. Raster functions available for raster analysis For example, you can use the Generate Raster task in ArcGIS REST API to run distributed raster analysis by giving a JSON object representation of a raster function chain. These raster functions and raster function template workflows can also be implemented in ArcGIS Pro, and with ArcGIS REST API, ArcGIS API for Python, and ArcGIS API for JavaScript. It will be available in a future release of This functionality is currently only supported in Map Viewer Classic.
