Build Mosaic Dataset Item Cache
Inserts the Cached
Raster function as the final step in all function chains within a mosaic
dataset.
يُدرج وظيفة Cached Raster كخطوة أخيرة في جميع سلاسل الوظائف ضمن مجموعة بيانات دمج الصور.
1.
Mosaic Dataset مجموعة بيانات دمج
الصور
The mosaic dataset where
you want to apply the cache function.
مجموعة بيانات دمج الصور حيث تريد تطبيق وظيفة
التخزين المؤقت.
Query
Definition (optional)
An SQL expression to select specific raster datasets within the mosaic
dataset on which you want the item cache built.
Define
Cache (optional)
Enable editing on the Cache properties.
· Checked—Add the Cached Raster function to the selected items. If an item
already has this function, it will not add another one. This is the default.
· Unchecked—No raster cache will be defined.
Generate
Cache (optional)
Choose to generate the cache files based on the properties defined in the
Cached Raster function, such as the location and the compression of the cache.
· Checked—Cache will be generated. This is the default.
· Unchecked—Cache will not be generated.
Cache Path
(optional)
Choose to overwrite the default location to save your cache. If the mosaic
dataset is inside of a file geodatabase, by default, the cache is saved in a
folder with the same name as the geodatabase and a .cache extension. If the
mosaic dataset is inside of an enterprise geodatabase, by default, the cache
will be saved inside of that geodatabase. Once created, the cache will always
save to the same location. To save the cache to a different location, you need
to first use the Repair Mosaic Dataset tool to specify a new location and run
this tool again.
Once an item cache is created, regenerating an item cache to a different
location is not possible by specifying a different cache path and rerunning
this tool. It will still generate the item cache in the location where it was
generated the first time. However, you can remove this function and insert a
new one with the new path or use the Repair Mosaic Dataset tool to modify the
cache path and run this tool to generate the item cache in a different
location.
Compression
Method (optional)
Choose how you want to compress your data for faster transmission.
· LOSSLESS— Retain the values of each pixel when generating cache. Lossless
has a compression ratio of approximately 2:1.
· LOSSY— Appropriate when your imagery is only used as a backdrop. Lossy has
the highest compression ratio (20:1) but groups similar pixel values to achieve
higher compression.
· NONE— Do not compress imagery. This will make your imagery slower to
transmit but faster to draw because it will not need to be decompressed when
viewed.
Compression
Quality (optional)
Set a compression quality when using the lossy method. The compression
quality value is between 1 and 100 percent, with 100 compressing the least.
Maximum
Allowed Rows (optional)
Limit the size of the cache dataset by number of rows. If value is more
than the number of rows in the dataset, the cache will not generate.
Maximum
Allowed Columns (optional)
Limit the size of the cache dataset by number of columns. If value is more
than the number of columns in the dataset, the cache will not generate.
Request
Size Type (optional)
Resample the cache using one of these two methods:
· PIXEL_SIZE_FACTOR— Set a scaling factor relative to the pixel size. To not
resample the cache, choose Pixel size factor and set the Request Size parameter
to 1.
· PIXEL_SIZE— Specify a pixel size for the cached raster.
Request
Size (optional)
Set a value to apply to the Request Size Type.
2.
