The Distance geoprocessing functions allow you to perform analysis that accounts for either straight-line (Euclidean) or weighted distance. Distance can be weighted by a simple cost (friction) surface, or in ways that account for vertical and horizontal restrictions to movement.
Distance analysis can be performed with the Spatial Analyst toolbox.
The following table lists the available geoprocessing functions and provides a brief description of each.
| Geoprocessing Function | Description |
|---|---|
Calculates accumulated distance for each cell to sources, allowing for straight-line distance, cost distance, and true surface distance, as well as vertical and horizontal cost factors. | |
Calculates distance allocation for each cell to the provided sources based on straight-line distance, cost distance, and true surface distance, as well as vertical and horizontal cost factors. | |
Calculates the sum of two accumulative cost distance rasters with the option to apply a threshold based on percentage or accumulative cost. | |
Calculates the optimal corridor connections between two or more input regions. | |
Calculates the optimal path from a source to a destination as a line. | |
Calculates the optimal path from a source to a destination as a raster. | |
Calculates the optimal connectivity network between two or more input regions. |
In AllSource 1.1 and later, the recommended geoprocessing functions for distance analysis are listed in the table above. In AllSource 1.2, distance analysis could also be performed using earlier versions these capabilities. These are available in the Legacy Distance geoprocessing function category.
