An overview of the Distance toolset

The Distance tools allow you to perform analysis that accounts for either straight-line (Euclidean) distance 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.

The following table lists the available tools and provides a brief description of each.

Tools in the Distance toolset

Tool	Description
Distance Accumulation	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.
Distance Allocation	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.
Least Cost Corridor	Calculates the sum of two accumulative cost distance rasters with the option to apply a threshold based on percentage or accumulative cost.
Optimal Corridor Connections	Calculates the optimal corridor connections between two or more input regions.
Optimal Path As Line	Calculates the optimal path from a source to a destination as a line.
Optimal Path As Raster	Calculates the optimal path from a source to a destination as a raster.
Optimal Region Connections	Calculates the optimal connectivity network between two or more input regions.
