Build Pyramids

Builds raster pyramids for your raster dataset.

This tool can also be used to delete pyramids. To delete pyramids, set the Pyramids Levels parameter to 0.

يبني أهرامات نقطية لمجموعة البيانات النقطية.

يمكن أيضًا استخدام هذه الأداة لحذف الأهرامات. لحذف الأهرامات ، اضبط معلمة Pyramids Levels على 0.

1.    Input Raster Dataset إدخال مجموعة البيانات النقطية

The raster dataset for which you want to build pyramids.

The input should have more than 1,024 rows and 1,024 columns.

مجموعة البيانات النقطية التي تريد بناء الأهرامات من أجلها.

يجب أن يحتوي الإدخال على أكثر من 1024 صفاً و 1024 عموداً.

2.    Pyramid levels (optional) مستويات الهرم (اختياري)

Choose the number of reduced-resolution dataset layers that will be built. The default value is -1, which will build full pyramids. A value of 0 will result in no pyramid levels.

To delete pyramids, set the number of levels to 0.

The maximum number of pyramid levels you can specify is 29. Any value that is 30 or higher will revert to a value of -1, which will create a full set of pyramids.

اختر عدد طبقات مجموعة البيانات منخفضة الدقة التي سيتم إنشاؤها. القيمة الافتراضية هي -1 ، والتي ستبني أهرامات كاملة. لن ينتج عن القيمة 0 مستويات هرمية.

لحذف الأهرامات ، اضبط عدد المستويات على 0.

الحد الأقصى لعدد مستويات الهرم التي يمكنك تحديدها هو 29. أي قيمة 30 أو أعلى ستعود إلى القيمة -1 ، والتي ستنشئ مجموعة كاملة من الأهرامات.

3.    Skip first level (optional) تخطي المستوى الأول (اختياري)

Choose whether to skip the first pyramid level. Skipping the first level will take up slightly less disk space, but it will slow down performance at these scales.

· Unchecked—The first pyramid level will be built. This is the default.

· Checked—The first pyramid level will not be built.

اختر ما إذا كنت تريد تخطي مستوى الهرم الأول. سيشغل تخطي المستوى الأول مساحة أقل قليلاً على القرص ، ولكنه سيؤدي إلى إبطاء الأداء في هذه المقاييس.

• بدون رادع - سيتم بناء أول مستوى هرمي. هذا هو الافتراضي.

• تم التحديد - لن يتم بناء المستوى الأول للهرم.

4.    Pyramid resampling technique (optional) تقنية إعادة التشكيل الهرمي (اختياري)

The resampling technique used to build your pyramids.

· NEAREST—This method uses the value of the closest cell to assign a value to the output cell when resampling. This is the default.

· BILINEAR—This method determines the new value of a cell based on a weighted distance average of the four nearest input cell centers.

· CUBIC—This method determines the new value of a cell based on fitting a smooth curve through the 16 nearest input cell centers.

تقنية إعادة التشكيل المستخدمة لبناء الأهرامات الخاصة بك.

• أقرب - تستخدم هذه الطريقة قيمة أقرب خلية لتعيين قيمة لخلية الإخراج عند إعادة التشكيل. هذا هو الافتراضي.

• الخطي - تحدد هذه الطريقة القيمة الجديدة للخلية بناءً على متوسط المسافة الموزونة لأقرب أربعة مراكز لخلايا الإدخال.

• CUBIC - تحدد هذه الطريقة القيمة الجديدة للخلية بناءً على ملاءمة منحنى سلس عبر أقرب 16 مركزًا لخلية الإدخال.

5.    Pyramid compression type (optional) نوع ضغط الهرم (اختياري)

The compression type to use when building the raster pyramids.

· DEFAULT—If the source data is compressed using a wavelet compression, it will build pyramids with the JPEG compression type; otherwise, LZ77 will be used. This is the default compression method.

· LZ77—The LZ77 compression algorithm will be used to build the pyramids. LZ77 can be used for any data type.

· JPEG—The JPEG compression algorithm to build pyramids. Only data that adheres to the JPEG compression specification can use this compression type. If JPEG is chosen, you can then set the compression quality.

· JPEG_YCbCr—A lossy compression using the luma (Y) and chroma (Cb and Cr) color space components.

· NONE—No compression will be used when building pyramids.

نوع الضغط المراد استخدامه عند بناء الأهرامات النقطية.

• افتراضي - إذا تم ضغط بيانات المصدر باستخدام ضغط الموجة ، فسيتم بناء أهرام بنوع ضغط JPEG ؛ خلاف ذلك ، سيتم استخدام LZ77. هذه هي طريقة الضغط الافتراضية.

• LZ77 - سيتم استخدام خوارزمية الضغط LZ77 لبناء الأهرامات. يمكن استخدام LZ77 لأي نوع بيانات.

• JPEG - خوارزمية ضغط JPEG لبناء الأهرامات. فقط البيانات التي تلتزم بمواصفات ضغط JPEG يمكنها استخدام هذا النوع من الضغط. إذا تم اختيار JPEG ، فيمكنك حينئذٍ ضبط جودة الضغط.

• JPEG_YCbCr - ضغط مع فقد باستخدام مكونات مساحة اللون luma (Y) و chroma (Cb و Cr).

• NONE - لن يتم استخدام الضغط عند بناء الأهرامات.

6.    Compression quality (1-100) (optional) جودة الضغط (1-100) (اختياري)

The compression quality to use when pyramids are built with the JPEG compression method. The value must be between 0 and 100. The values closer to 100 will produce a higher-quality image, but the compression ratio will be lower.

جودة الضغط التي يجب استخدامها عند إنشاء الأهرامات باستخدام طريقة ضغط JPEG. يجب أن تكون القيمة بين 0 و 100. القيم الأقرب إلى 100 ستنتج صورة عالية الجودة ، لكن نسبة الضغط ستكون أقل.

7.    Skip Existing (optional) تخطي الموجود (اختياري)

Specify whether to build pyramids only when they are missing or regenerate them even if they exist.

· Unchecked—Pyramids will be built even if they already exist; therefore, existing pyramids will be overwritten. This is the default.

· Checked—Pyramids will only be built if they do not already exist. Skip Existing (optional)

حدد ما إذا كنت تريد بناء الأهرامات فقط عند فقدها أو تجديدها حتى لو كانت موجودة.

• بدون رادع - سيتم بناء الأهرامات حتى لو كانت موجودة بالفعل ؛ لذلك ، سيتم الكتابة فوق الأهرامات الموجودة. هذا هو الافتراضي.

• تم التحديد - سيتم بناء الأهرامات فقط إذا لم تكن موجودة بالفعل.Specify whether to build pyramids only when they are missing or regenerate them even if they exist.
