Repair Mosaic Dataset Paths (Data Management)

Summary

Resets paths to source imagery if you have moved or copied a mosaic dataset.

Usage

• You need to know the file path location in order to change it. You can use the Export Mosaic Dataset Paths tool to retrieve the original path names.

• You can type an asterisk (*) as the original path if you wish to change all your paths.

• Database fragmentation and frequent data manipulation can significantly increase the size of a mosaic dataset. If the database size is large due to constant transactions, run the Compact tool.

Parameters

Dialog

Label	Explanation	Data Type
Mosaic Dataset	The mosaic dataset with the broken paths.	Mosaic Layer
Paths List	A list of the paths to remap. Include the current path stored in the mosaic dataset and the path to which it will be changed. You can enter an asterisk (*) as the original path if you wish to change all your paths.	Value Table
Query Definition (Optional)	An SQL expression to limit the repairs to selected rasters within the mosaic dataset.	SQL Expression

Derived Output

Label	Explanation	Data Type
Repaired Input Mosaic Dataset	The updated mosaic dataset.	Mosaic Layer

Python

arcpy.management.RepairMosaicDatasetPaths(in_mosaic_dataset, paths_list, {where_clause})

Name	Explanation	Data Type
in_mosaic_dataset	The mosaic dataset with the broken paths.	Mosaic Layer
paths_list [[original_path, {new_path}],...]	A list of the paths to remap. Include the current path stored in the mosaic dataset and the path to which it will be changed. You can enter an asterisk (*) as the original path if you wish to change all your paths.	Value Table
where_clause (Optional)	An SQL expression to limit the repairs to selected rasters within the mosaic dataset.	SQL Expression

Derived Output

Name	Explanation	Data Type
out_mosaic_dataset	The updated mosaic dataset.	Mosaic Layer
