1.
Input point features أدخل معالم
النقط
The input point features
for which to calculate the statistics in a neighborhood around each output
cell.
The input can be either
a point or multipoint feature class.
معالم نقطة الإدخال المطلوب حساب الإحصائيات في حي
حول كل خلية ناتجة.
يمكن أن يكون الإدخال إما فئة ميزة نقطة أو متعددة
النقاط.
Field
The field that the specified statistic will be calculated for. It can be
any numeric field of the input features.
It can be the Shape field if the input features contain z-values.
Output raster
The output point statistics 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
the parameter value, the environment cell size value will be used if specified;
otherwise, additional rules will be used to calculate it from the other inputs.
See the usage for more detail.
Neighborhood (optional)
Dictates the shape of the area around each input point location used to
calculate the statistic.
The parameters and descriptions for each of the neighborhood types follow.
· Annulus Inner radius Outer radius Units
A torus (donut-shaped) neighborhood
defined by an inner radius and an outer radius. The default annulus is an inner
radius of one cell and an outer radius of three cells.
· Circle Radius Units
A circular neighborhood with the given
radius. The default radius is three cells.
· Rectangle Height Width Units
A rectangular neighborhood defined by
the height and width. The default is a square with a height and width of three
cells.
· Wedge Radius Start angle End angle Units
A wedge-shaped neighborhood defined by a
radius, the start angle, and the end angle. The wedge extends counterclockwise
from the starting angle to the ending angle. Angles are specified in degrees,
with 0 or 360 representing east. Negative angles can be used. The default wedge
is from 0 to 90 degrees, with a radius of 3 cells.
The distance units for the parameters can be specified in cell units or
map units. Cell units is the default.
The default neighborhood is a square rectangle with a width and height of
three cells.
Statistics type (optional)
Specifies the statistic type to be calculated.
The calculation is performed on the values of the specified field of the
point input in the neighborhood of each output raster cell.
· MEAN—Calculates the average of the field values in each neighborhood.
· MAJORITY—Determines the most frequently occurring field value in each
neighborhood. In the case of a tie, the lower value is used.
· MAXIMUM—Determines the largest field value in each neighborhood.
· MEDIAN—Determines the median field value in each neighborhood. In the case
of an even number of points in the neighborhood, the result will be the lower
of the two middle values.
· MINIMUM—Determines the smallest field value in each neighborhood.
· MINORITY—Determines the least frequently occurring field value in each
neighborhood. In the case of a tie, the lower value is used.
· RANGE—Calculates the range (difference between largest and smallest) of
the field values in each neighborhood.
· STD—Calculates the standard deviation of the field values in each
neighborhood.
· SUM—Calculates the total of the field values in each neighborhood.
· VARIETY—Calculates the number of unique field values in each neighborhood.
The available choices for the statistics type is determined by the numeric
type of the specified field.
