locations.
This is a raster or
feature dataset that identifies the cells or locations to which the Euclidean
distance for every output cell location is calculated.
For rasters, the input
type can be integer or floating point.

Output direction raster
The output Euclidean direction raster.
The direction raster contains the calculated direction, in degrees, that
each cell center is from the closest source cell center.
The range of values is from 0 degrees to 360 degrees, with 0 reserved for
the source cells. Due east (right) is 90, and the values increase clockwise
(180 is south, 270 is west, and 360 is north).
The output raster is of integer type.
Input barrier raster or feature
class (optional)
The dataset that defines the barriers.
The barriers can be defined by an integer or a floating-point raster, or
by a feature layer.
Maximum distance (optional)
The threshold that the accumulative distance values cannot exceed.
If an accumulative Euclidean distance value exceeds this value, the output
value for the cell location will be NoData.
The default distance is to the edge of the output raster.
Output cell size (optional)
The cell size of the output raster that will be created.
This parameter can be defined by a numeric value or obtained from an
existing raster dataset. If the cell size hasn't been explicitly specified as
