【问题描述】
The Remove rasters from Mosaic Dataset tool does not have the option for spatial query. The code below illustrates the use of ArcPy to remove rasters based on a polygon area of interest.

    The code sample can be used as a stand alone Python script to remove rasters from a mosaic dataset based on a spatial query. A polygon is used in this example.

    1. 
     
    
import arcpy
    
from arcpy import env
    

    
#set variables
    
env.workspace = r"D:\Documents\Northwest.gdb"
    
clipShape = "parks"
    
mosaicDataset = "CityOfPortland"
    

    
# Make a mosaic layer to be able to select the footprint
    
arcpy.MakeMosaicLayer_management(mosaicDataset, "mdlayer")
    

    
# Select the footprint based on polygon clipShape using the intersect method
    
arcpy.SelectLayerByLocation_management("mdlayer", "INTERSECT", clipShape)
    

    
# Run the remove rasters tool without any query on the selection
    
arcpy.RemoveRastersFromMosaicDataset_management("mdlayer", "#", "UPDATE_BOUNDARY", "MARK_OVERVIEW_ITEMS")
