Region Group

For each cell in the output, the identity of the connected region to which that cell belongs is recorded. A unique number is assigned to each region.

لكل خلية في المخرجات ، يتم تسجيل هوية المنطقة المتصلة التي تنتمي إليها تلك الخلية. يتم تخصيص رقم فريد لكل منطقة.

1. Input raster أدخل البيانات النقطية

The input raster whose unique connected regions will be identified.

It must be of integer type.

البيانات النقطية المدخلة التي سيتم تحديد مناطقها المتصلة الفريدة.

يجب أن يكون من نوع عدد صحيح.

Output raster

The output region group raster.

The output is always of integer type.

Number of neighbors to use (optional)

The number of neighboring cells to use in evaluating connectivity between cells.

·      FOUR—Defines connectivity between cells of the same value only if the cells are directly to the left, right, above, or below each of the four nearest neighbors. If two cells with the same value are diagonal from one another, they are not considered connected. This is the default.

·      EIGHT—Defines connectivity between cells of the same value if they are within the immediate eight-cell neighborhood (eight nearest neighbors) of each other. This includes to the right, left, above, or diagonal to each other.

Zone grouping method (optional)

Defines which cell values should be considered when testing for connectivity.

·      WITHIN—Tests connectivity between input values that are the same within the same zone.The only cells that can be grouped are cells from the same zone (value) that meet the spatial requirements of connectivity specified by the Number of neighbours parameter (four-way or eight-way). This is the default.

·      CROSS—Tests connectivity by the spatial requirements specified by the Number of neighbors to use parameter between cells with any values, except for the value identified to be excluded by the Excluded value parameter.When CROSS is used, a value for the Excluded value parameter must be input.

Add link field to output (optional)

Specifies whether a link field is added to the table of the output.

·      Checked—A LINK item will be added to the table of the output raster. This item stores the original values for each newly created zone, from disconnected regions, from the input raster before they are regrouped. This is the default.

·      Unchecked—The attribute table for the output raster will only contain the Value and Count items.

Excluded value (optional)

Identifies a value such that if a cell location contains the value, no spatial connectivity will be evaluated regardless how the number of neighbors is specified (FOUR or EIGHT).

Cells with the excluded value will be treated as NoData and are eliminated from calculations. Cell locations that contain the excluded value will receive 0 on the output raster.

The excluded value is similar to the concept of a background value, or setting a mask in the environment for a single run of the tool. A value must be specified for this parameter if the CROSS keyword is specified.

2. Output raster البيانات النقطية المخرجة

The output region group raster.

The output is always of integer type.

مجموعة منطقة الإخراج النقطية.

الإخراج دائمًا من نوع عدد صحيح.

• FOUR - لتحديد الاتصال بين الخلايا التي لها نفس القيمة فقط إذا كانت الخلايا على اليسار أو اليمين أو فوق أو أسفل كل من أقرب أربعة جيران. إذا كانت خليتان بنفس القيمة قطريتين من بعضهما البعض ، فلا يتم اعتبارهما متصلتين. هذا هو الافتراضي.

• ثمانية — يحدد الاتصال بين الخلايا التي لها نفس القيمة إذا كانت داخل الجوار المباشر المكون من ثماني خلايا (ثمانية أقرب جيران) لبعضها البعض. يتضمن ذلك اليمين أو اليسار أو فوق أو قطريًا لبعضها البعض.

يحدد ما إذا كان حقل الارتباط يُضاف إلى جدول الإخراج.

• تم التحديد - ستتم إضافة عنصر LINK إلى جدول البيانات النقطية للإخراج. يخزن هذا العنصر القيم الأصلية لكل منطقة تم إنشاؤها حديثًا ، من المناطق غير المتصلة ، من البيانات النقطية للإدخال قبل إعادة تجميعها. هذا هو الافتراضي.

Cells with the excluded value will be treated as NoData and are eliminated from calculations. Cell locations that contain the excluded value will receive 0 on the output raster.

The excluded value is similar to the concept of a background value, or setting a mask in the environment for a single run of the tool. A value must be specified for this parameter if the CROSS keyword is specified.

6. Excluded value (optional) القيمة المستبعدة (اختياري)

يحدد قيمة مثل أنه إذا احتوى موقع الخلية على القيمة ، فلن يتم تقييم أي اتصال مكاني بغض النظر عن كيفية تحديد عدد الجيران (أربعة أو ثمانية).

ستتم معاملة الخلايا ذات القيمة المستبعدة على أنها NoData وسيتم حذفها من العمليات الحسابية. ستتلقى مواقع الخلايا التي تحتوي على القيمة المستبعدة 0 على البيانات النقطية للإخراج.

القيمة المستبعدة مماثلة لمفهوم قيمة الخلفية ، أو إعداد قناع في البيئة لتشغيل واحد للأداة. يجب تحديد قيمة لهذه المعلمة إذا تم تحديد الكلمة الأساسية CROSS.
