![]() ![]() Generates a forecasted layer using the output from the Generate Trend function. The change analysis raster must be generated by the Analyze Changes Using CCDC tool or the Analyze Changes Using LandTrendr tool, or the CCDC Analysis raster function or the LandTrendr Analysis raster function.Įstimates the trend for each pixel along a dimension for a given variable in a multidimensional raster.Ĭalculates the apparent temperature based on air temperature and humidity.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.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.Ĭalculates the normalized difference vegetation index (NDVI) values using the red and near-infrared bands.Ĭomputes the NDVI from the input image and applies a color map to the result. The Detect Change Using Change Analysis function generates a raster layer containing pixel date-of-change information using the change analysis raster. Analysisĭivides the 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.Įvaluates changes in pixel values over time using the Continuous Change Detection and Classification (CCDC) method and generates a change analysis raster containing the model results.Ĭomputes the differences between two categorical or continuous raster datasets. You can change the properties of a raster function on the General tab, including the name, description, output pixel type, and multidimensional rules. ![]() Global functions do not support multidimensional rasters as inputs. To learn more, see Global functions.Īll local raster functions-more than 100-support multidimensional rasters as inputs. They work similarly to geoprocessing tools and can use environment settings that you specify. Global functions can be identified by the hammer picture within the function button. Global raster functions can be chained together with other functions, but they process data on a specified resolution and extent. The raster functions are organized in a raster function template, allowing you to create various processed products by chaining together multiple functions. This means they can be applied quickly, without the time it would otherwise take to create a processed file on disk. These functions are applied to the raster data on the fly as the data is accessed and viewed. ![]() The raster functions allow you to define processing operations that can be applied to one or more rasters. ![]()
