ArcGIS Pro now has a new type of raster function called global functions. Global functions provide you with the ability to perform processing at a specific resolution and extent. By default, global functions process rasters at the source resolution and full extent. This means that applying a global function may take some time, depending on the size of the outputs. You need to exercise prudence when using global functions, as applying them on inputs that are large, such as mosaic datasets, may result in long processing times.
Global functions are distinguishable from regular raster functions in many different ways. All global functions have a hammer icon to distinguish it from other raster functions. When you open a global function, or a raster function template that contains a global function, a notification will be displayed at the top of the function page indicating that these functions may take some time to complete. When editing the parameters of a global function in the Raster Function Editor or using a global function in a raster function template, the global function node has an icon on it that distinguishes it from regular raster functions.
It is recommended that when using global functions, you process data using the distributed raster analysis tools. This allows you to process data in a distributed fashion and allows processing time by global functions to be minimized.
List of global raster functions
Calculates, for each cell, its least-cost source based on the least accumulative cost over a cost surface.
Calculates the least accumulative cost distance for each cell from or to the least-cost source over a cost surface.
Calculates, for each cell, the nearest source based on Euclidean distance.
Calculates, for each cell, the Euclidean distance to the closest source.
Calculates 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.
Calculates the least-cost path from a source to a destination. The least accumulative cost distance is calculated for each pixel over a cost surface, to the nearest source. This produces an output raster that records the least-cost path, or paths, from selected locations to the closest source pixels defined within the accumulative cost surface, in terms of cost distance.
Determines the raster surface locations visible to a set of observer features using geodesic methods
Calculates statistics on values of a raster within the zones of another dataset.
Geoprocessing environment settings
Geoprocessing Environment settings for global functions are controlled at the application level. Setting processing environments in ArcGIS Pro can be done by selecting the Environments button on the Analysis tab. See Analysis environments and Spatial Analyst for additional details on environment settings.
