Distance measure operations calculate distance away from cells designated as the source cells. For example, to get the distance between cells and , we can use the following formula: or Cell Size . If the cell size were 30 meters, the distance would be meters.

In raster data analysis, two types of distance measure operations are supported:

Figure Shows Two Typeso of Distance Measure Operations

Cost Path

The Cost Path operation uses the created distance dataset to identify the shortest cost path a destination for the objects in the source dataset specified in the Cost Path dialog box.

Path Type

Each Cell

Create the cost path for each source cell of the specified objects

Each Zone

Creates the cost path for each zone, a zone is consisted of cells with the same cell value.

Best Single

Creates only one cost path, which is the shortest of the cost paths.
