Synchronize Mosaic Dataset

Keeps your mosaic dataset up to date. In addition to syncing data, you can update overviews if the underlying imagery has been changed, generate new overviews and cache, and restore the original configuration of mosaic dataset items. You can also remove paths to source data with this tool. To repair paths, you need to use the Repair Mosaic Dataset Paths tool.

Synchronization is a one-way operation: changes in the source data can be synchronized to the mosaic dataset’s attribute table, thereby updating the mosaic dataset's attribute table. Changes in the mosaic dataset's attribute table will not affect the source data.

Changes made with the synchronization cannot be undone. You may want to create a backup copy if you've made modifications to your mosaic data that could be overwritten.

يحافظ على مجموعة بيانات دمج الصور الخاصة بك محدثة. بالإضافة إلى مزامنة البيانات ، يمكنك تحديث النظرات العامة إذا تم تغيير الصور الأساسية ، وإنشاء نظرات عامة جديدة وذاكرة تخزين مؤقت ، واستعادة التكوين الأصلي لعناصر مجموعة بيانات دمج الصور. يمكنك أيضًا إزالة المسارات إلى بيانات المصدر باستخدام هذه الأداة. لإصلاح المسارات ، تحتاج إلى استخدام أداة Repair Mosaic Dataset Paths.

المزامنة هي عملية أحادية الاتجاه: يمكن مزامنة التغييرات في بيانات المصدر مع جدول سمات مجموعة بيانات دمج الصور ، وبالتالي تحديث جدول سمات مجموعة بيانات دمج الصور. لن تؤثر التغييرات في جدول بيانات مجموعة البيانات دمج الصور على بيانات المصدر.

لا يمكن التراجع عن التغييرات التي تم إجراؤها مع المزامنة. قد ترغب في إنشاء نسخة احتياطية إذا قمت بإجراء تعديلات على بيانات دمج الصور الخاصة بك والتي يمكن الكتابة فوقها.
