Line Statistics
Calculates a statistic
on the attributes of lines in a circular neighborhood around each output cell.

حول كل خلية ناتجة.
1.
Input polyline features أدخل معالم
الخطوط المتعددة
The input polyline
features for which to calculate the statistics in a neighbourhood around each
output cell.
معالم الإدخال متعدد الخطوط التي يتم من أجلها
حساب الإحصائيات في حي حول كل خلية ناتجة.
Field
The field that the specified statistic will be calculated for. It can be
any numeric field of the input features.
When the statistics type is set to LENGTH, the Field can be set to None.
It can be the Shape field if the input features contain z-values.
Output raster
The output line 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.
Search radius (optional)
Search radius to calculate the desired statistic within, in map units.
The default radius is five times the output cell size.
Statistics type (optional)
Specifies the statistic type to be calculated.
Statistics are calculated on the value of the specified field for all lines
within the neighborhood.
· MEAN—Calculates the average field value in each neighborhood, weighted by
the length.The form of the calculation is:
o Mean = (sum of (length * field_value)) / (sum_of_length)
Only the part of the length that falls
within the neighborhood is used.
· MAJORITY—Determines the value having the greatest length of line in the
neighborhood.
· MAXIMUM—Determines the largest value in the neighborhood.
· MEDIAN—Determines the median value, weighted by the length.Conceptually,
all line segments in the neighborhood are sorted by value and placed end-to-end
in a straight line. The value of the segment at the midpoint of the straight
line is the median.
· MINIMUM—Calculates smallest value in each neighborhood.
· MINORITY—The value having the least length of line in the neighborhood.
· RANGE—The range of values (maximum–minimum).
· VARIETY—The number of unique values.
· LENGTH—The total line length in the neighborhood. If the value of the
field is other than 1, the lengths are multiplied by the item value before
adding them together. This option can be used when the Field is set to None.
When the specified field is integer, the available statistic choices are
Mean, Majority, Maximum, Median, Minimum, Minority, Range, and Variety. When
the field is floating point, the only allowed statistics are Mean, Maximum,
Minimum, and Range.

يحدد النوع الإحصائي المطلوب حسابه.
يتم حساب الإحصائيات على أساس قيمة الحقل المحدد
لجميع السطور داخل الحي.
• يعني - لحساب متوسط
قيمة الحقل في كل حي ، مرجحًا بالطول. شكل الحساب هو:
o
المتوسط = (مجموع (الطول * قيمة_المجال)) / (مجموع_الطول)
يتم استخدام جزء الطول الذي يقع داخل الحي فقط.
• MAJORITY - تحدد القيمة التي لها أكبر طول للخط في المنطقة المجاورة.
• الحد الأقصى — يحدد
أكبر قيمة في الحي.
• MEDIAN -
تحدد القيمة المتوسطة ، مرجحة بالطول. من الناحية المفاهيمية ، يتم فرز جميع مقاطع
الخط في الحي حسب القيمة ويتم وضعها من طرف إلى طرف في خط مستقيم. قيمة القطعة في
منتصف الخط المستقيم هي الوسيط.
• الحد الأدنى — تحسب
أصغر قيمة في كل حي.
• الأقلية - القيمة التي
لها أقل طول للخط في الحي.
• RANGE -
نطاق القيم (الحد الأقصى - الحد الأدنى).
• VARIETY - عدد القيم الفريدة.
• الطول — إجمالي طول
الخط في الحي. إذا كانت قيمة الحقل غير 1 ، يتم ضرب الأطوال في قيمة العنصر قبل
إضافتها معًا. يمكن استخدام هذا الخيار عند ضبط الحقل على بلا.
عندما يكون الحقل المحدد عددًا صحيحًا ، فإن
الاختيارات الإحصائية المتاحة هي المتوسط والأغلبية والحد الأقصى والوسيط والحد
الأدنى والأقلية والمدى والتنوع. عندما يكون الحقل عبارة عن فاصلة عائمة ، فإن
الإحصائيات المسموح بها فقط هي "المتوسط" و "الحد الأقصى" و
"الحد الأدنى" و "النطاق".
