These legacy tools analyze distance and proximity.
The Legacy Use Proximity tools allow you to access the distance and proximity analysis tools available in previous releases of ArcGIS. These tools 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. To take advantage of available updated functionality, use the tools at the main level of the Use Proximity toolset.
Calculates the Euclidean distance from a single source or set of sources.
Calculates the least accumulative cost distance from or to the least-cost source, while accounting for surface distance along with horizontal and vertical cost factors.
Calculates the least-cost path from a source to a destination as a line feature.
Calculates the optimum cost network from a set of input regions.
Calculates the least cost polyline path between sources and destinations.
Calculates specific paths between known sources and known destinations.
