1. Input raster or feature source data إدخال البيانات النقطية أو ميزة مصدر البيانات
The input source
locations.
This is a raster or
feature dataset that identifies the cells or locations from or to which the
least accumulated cost distance for every output cell location is calculated.
For rasters, the input
type can be integer or floating point.

المواقع منها أو التي يتم فيها حساب أقل مسافة تكلفة متراكمة لكل موقع خلية إخراج.
بالنسبة إلى البيانات النقطية ، يمكن أن يكون نوع
الإدخال عددًا صحيحًا أو نقطة عائمة.
Input cost raster
A raster defining the impedance or cost to move planimetrically through
each cell.
The value at each cell location represents the cost-per-unit distance for moving
through the cell. Each cell location value is multiplied by the cell resolution
while also compensating for diagonal movement to obtain the total cost of
passing through the cell.
The values of the cost raster can be integer or floating point, but they
cannot be negative or zero (you cannot have a negative or zero cost).
Output backlink raster
The output cost backlink raster.
The backlink raster contains values 0 through 8, which define the
direction or identify the next neighboring cell (the succeeding cell) along the
least accumulative cost path from a cell to reach its least-cost source.
If the path is to pass into the right neighbor, the cell will be assigned
the value 1, 2 for the lower right diagonal cell, and continue clockwise. The
value 0 is reserved for source cells.
Maximum distance (optional)
The threshold that the accumulative cost values cannot exceed.
If an accumulative cost distance value exceeds this value, the output
value for the cell location will be NoData. The maximum distance is the extent
for which the accumulative cost distances are calculated.
The default distance is to the edge of the output raster.
Output distance raster (optional)
The output cost distance raster.
The cost distance raster identifies, for each cell, the least accumulative
cost distance over a cost surface to the identified source locations.
A source can be a cell, a set of cells, or one or more feature locations.
The output raster is of floating-point type.
Multiplier to apply to costs
(optional)
The multiplier to apply to the cost values.
This allows for control of the mode of travel or the magnitude at a
source. The greater the multiplier, the greater the cost to move through each
cell.
The values must be greater than zero. The default is 1.
Start cost (optional)
The starting cost from which to begin the cost calculations.
Allows for the specification of the fixed cost associated with a source.
Instead of starting at a cost of zero, the cost algorithm will begin with the
value set by Start cost.
The values must be zero or greater. The default is 0.
Accumulative cost resistance rate
(optional)
This parameter simulates the increase in the effort to overcome costs as
the accumulative cost increases. It is used to model fatigue of the traveler.
The growing accumulative cost to reach a cell is multiplied by the resistance
rate and added to the cost to move into the subsequent cell.
It is a modified version of a compound interest rate formula that is used
to calculate the apparent cost of moving through a cell. As the value of the
resistance rate increases, it increases the cost of the cells that are visited
later. The greater the resistance rate, the more additional cost is added to
reach the next cell, which is compounded for each subsequent movement. Since
the resistance rate is similar to a compound rate and generally the
accumulative cost values are very large, small resistance rates are suggested,
such as 0.02, 0.005, or even smaller, depending on the accumulative cost
values.
The values must be zero or greater. The default is 0.
Capacity (optional)
The cost capacity for the traveler for a source.
The cost calculations continue for each source until the specified
capacity is reached.
The values must be greater than zero. The default capacity is to the edge
of the output raster.
Travel direction (optional)
Specifies the direction of the traveler when applying the source
resistance rate and the source starting cost.
· FROM_SOURCE—The source resistance rate and source starting cost will be
applied beginning at the input source, and travel out to the non-source cells.
This is the default.
· TO_SOURCE—The source resistance rate and source starting cost will be
applied beginning at each non-source cell, and travel back to the input source.
If you select the String option, you can choose between from and to
options, which will be applied to all sources.
If you select the Field option, you can select the field from the source
data that determines the direction to use for each source. The field must
contain the text string FROM_SOURCE or TO_SOURCE.
