Zonal Statistics
Calculates statistics on
values of a raster within the zones of another dataset.
تحسب الإحصائيات الخاصة بقيم البيانات النقطية
داخل مناطق مجموعة بيانات أخرى.
1.
Input raster or feature zone data ادخل
البيانات النقطية او بيانات معلم البيانات
Dataset that defines the
zones.
The zones can be defined
by an integer raster or a feature layer.
مجموعة البيانات التي تحدد المناطق.
يمكن تحديد المناطق بواسطة عدد صحيح نقطي أو طبقة
معالم.
Zone field
Field that holds the values that define each zone.
It can be an integer or a string field of the zone dataset.
Input value raster
Raster that contains the values on which to calculate a statistic.
Output raster
The output zonal statistics raster.
Statistics type (optional)
Statistic type to be calculated.
· MEAN—Calculates the average of all cells in the value raster that belong
to the same zone as the output cell.
· MAJORITY—Determines the value that occurs most often of all cells in the
value raster that belong to the same zone as the output cell.
· MAXIMUM—Determines the largest value of all cells in the value raster that
belong to the same zone as the output cell.
· MEDIAN—Determines the median value of all cells in the value raster that
belong to the same zone as the output cell.
· MINIMUM—Determines the smallest value of all cells in the value raster
that belong to the same zone as the output cell.
· MINORITY—Determines the value that occurs least often of all cells in the
value raster that belong to the same zone as the output cell.
· RANGE—Calculates the difference between the largest and smallest value of
all cells in the value raster that belong to the same zone as the output cell.
· STD—Calculates the standard deviation of all cells in the value raster
that belong to the same zone as the output cell.
· SUM—Calculates the total value of all cells in the value raster that
belong to the same zone as the output cell.
· VARIETY—Calculates the number of unique values for all cells in the value
raster that belong to the same zone as the output cell.
Ignore NoData in calculations
(optional)
Denotes whether NoData values in the Value input will influence the
results of the zone that they fall within.
· Checked—Within any particular zone, only cells that have a value in the
input Value raster will be used in determining the output value for that zone.
NoData cells in the Value raster will be ignored in the statistic calculation.
This is the default.
· Unchecked—Within any particular zone, if any NoData cells exist in the
Value raster, it is deemed that there is insufficient information to perform
statistical calculations for all the cells in that zone; therefore, the entire
zone will receive the NoData value on the output raster.

It can be an integer or
a string field of the zone dataset.
الحقل الذي يحتوي على القيم التي تحدد كل منطقة.

بيانات المنطقة.

تشير إلى ما إذا كانت قيم NoData في
إدخال القيمة ستؤثر على نتائج المنطقة التي تقع ضمنها.
• تم التحديد - داخل أي
منطقة معينة ، سيتم استخدام الخلايا التي لها قيمة في قيمة الإدخال النقطية فقط في
تحديد قيمة الإخراج لتلك المنطقة. سيتم تجاهل خلايا NoData في
القيمة النقطية في الحساب الإحصائي. هذا هو الافتراضي.
• غير محدد - داخل أي
منطقة معينة ، إذا كانت هناك أي خلايا NoData
موجودة في قيمة البيانات النقطية ، فيُعتبر أنه لا توجد معلومات كافية لإجراء
حسابات إحصائية لجميع الخلايا في تلك المنطقة ؛ لذلك ، ستتلقى المنطقة بأكملها
قيمة NoData على البيانات النقطية
للإخراج.
