Define Overviews

Lets you set how mosaic dataset overviews are generated. The settings made with this tool are used by the Build Overviews tool.

يتيح لك تعيين كيفية إنشاء النظرات العامة لمجموعة بيانات دمج الصور. يتم استخدام الإعدادات التي تم إجراؤها باستخدام هذه الأداة بواسطة أداة "نظرة عامة على الإنشاء".

1.    Mosaic Dataset مجموعة بيانات دمج الصور

The mosaic dataset that you want to build overviews on.

مجموعة بيانات دمج الصور التي تريد إنشاء نظرة عامة عليها.

Output Location (optional)

The folder or geodatabase to store the overviews.

Extent from Dataset (optional)

A raster dataset or feature class to define the extent of the overviews.

Extent (optional)

Manually set the extent using the following minimum and maximum x and y coordinates.

The mosaic dataset boundary will determine the extent of the overviews if you do not define an extent.

Pixel Size (optional)

If you prefer not to use all the raster's pyramids, specify a base pixel size at which your overviews will be generated.

The units for this parameter are the same as the spatial reference of the mosaic dataset.

Number Of Levels (optional)

Specify the number of levels of overviews that you want to generate overviews. A value of -1 will determine an optimal value for you.

Number Of Rows (optional)

Set the number of rows (in pixels) for each tile.

Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files.

Number Of Columns (optional)

Set the number of columns (in pixels) for each tile.

Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files.

Overview Sampling Factor (optional)

Set a ratio to determine the size of the next overview. For example, if the cell size of the first level is 10, and the overview factor is 3, then the next overview pixel size will be 30.

Force Overview Tiles (optional)

Generate overviews at all levels, or only above existing pyramid levels.

·      Unchecked—Create overviews above the raster pyramid levels. This is the default.

·      Checked—Create overviews at all levels.

Resampling Method (optional)

Choose an algorithm for aggregating pixel values in the overviews.

·      NEAREST— The fastest resampling method because it minimizes changes to pixel values. Suitable for discrete data, such as land cover. If the Key Metadata Data Type is thematic, then nearest neighbor will be the default.

·      BILINEAR—Calculates the value of each pixel by averaging (weighted for distance) the values of the surrounding 4 pixels. Suitable for continuous data.This is the default, unless the Key Metadata Data Type is thematic.

·      CUBIC— Calculates the value of each pixel by fitting a smooth curve based on the surrounding 16 pixels. Produces the smoothest image, but can create values outside of the range found in the source data. Suitable for continuous data.

Compression Method (optional)

Define the type of data compression to store the overview images.

·      JPEG—A lossy compression. This is the default, unless the Key Metadata Data Type is thematic. This compression method is only valid if the mosaic dataset items adhere to JPEG specifications.

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

·      None—No data compression.

·      LZW—A lossless compression. If the Key Metadata Data Type is thematic, then nearest neighbor will be the default.

Compression Quality (optional)

Choose a value from 1 - 100. Higher values generate better quality outputs, but they create larger files.

ستحدد حدود مجموعة بيانات دمج الصور مدى النظرات العامة إذا لم تحدد نطاقًا.

5.    Pixel Size (optional) حجم البكسل (اختياري)

If you prefer not to use all the raster's pyramids, specify a base pixel size at which your overviews will be generated.

The units for this parameter are the same as the spatial reference of the mosaic dataset.

إذا كنت تفضل عدم استخدام جميع أهرامات خطوط المسح ، فحدد حجم البكسل الأساسي الذي سيتم إنشاء النظرات العامة الخاصة بك به.

وحدات هذه المعلمة هي نفس الإسناد المكاني لمجموعة بيانات دمج الصور.

6.    Number Of Levels (optional) عدد المستويات (اختياري)

Specify the number of levels of overviews that you want to generate overviews. A value of -1 will determine an optimal value for you.

7.    Number Of Rows (optional) عدد الصفوف (اختياري)

Set the number of rows (in pixels) for each tile.

Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files.

عيّن عدد الصفوف (بالبكسل) لكل بلاطة.

القيم الأكبر ستؤدي إلى عدد أقل من النظرات العامة الفردية ، وتزيد من احتمالية أنك ستحتاج إلى إعادة إنشاء النظرات العامة ذات المستوى الأدنى. ستؤدي القيمة الأصغر إلى ملفات أكثر وأصغر.

8.    Number Of Columns (optional) عدد الأعمدة (اختياري)

Set the number of columns (in pixels) for each tile.

Set a ratio to determine the size of the next overview. For example, if the cell size of the first level is 10, and the overview factor is 3, then the next overview pixel size will be 30.

Force Overview Tiles (optional)

Generate overviews at all levels, or only above existing pyramid levels.

·Unchecked—Create overviews above the raster pyramid levels. This is the default.

·Checked—Create overviews at all levels.

Resampling Method (optional)

Choose an algorithm for aggregating pixel values in the overviews.

·NEAREST— The fastest resampling method because it minimizes changes to pixel values. Suitable for discrete data, such as land cover. If the Key Metadata Data Type is thematic, then nearest neighbor will be the default.

·BILINEAR—Calculates the value of each pixel by averaging (weighted for distance) the values of the surrounding 4 pixels. Suitable for continuous data.This is the default, unless the Key Metadata Data Type is thematic.

·CUBIC— Calculates the value of each pixel by fitting a smooth curve based on the surrounding 16 pixels. Produces the smoothest image, but can create values outside of the range found in the source data. Suitable for continuous data.

Compression Method (optional)

Define the type of data compression to store the overview images.

·JPEG—A lossy compression. This is the default, unless the Key Metadata Data Type is thematic. This compression method is only valid if the mosaic dataset items adhere to JPEG specifications.

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

·None—No data compression.

·LZW—A lossless compression. If the Key Metadata Data Type is thematic, then nearest neighbor will be the default.

Compression Quality (optional)

Choose a value from 1 - 100. Higher values generate better quality outputs, but they create larger files.

Extent (optional)

Manually set the extent using the following minimum and maximum x and y coordinates.

The mosaic dataset boundary will determine the extent of the overviews if you do not define an extent.

Pixel Size (optional)

If you prefer not to use all the raster's pyramids, specify a base pixel size at which your overviews will be generated.

The units for this parameter are the same as the spatial reference of the mosaic dataset.

Number Of Levels (optional)

Specify the number of levels of overviews that you want to generate overviews. A value of -1 will determine an optimal value for you.

Number Of Rows (optional)

Set the number of rows (in pixels) for each tile.

Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files.

Number Of Columns (optional)

Set the number of columns (in pixels) for each tile.

Larger values will result in fewer, larger individual overviews, and increase the likelihood that you will need to regenerate lower level overviews. A smaller value will result in more, smaller files.

Overview Sampling Factor (optional)

Set a ratio to determine the size of the next overview. For example, if the cell size of the first level is 10, and the overview factor is 3, then the next overview pixel size will be 30.

Extent from Dataset (optional)

A raster dataset or feature class to define the extent of the overviews.
