arcpy查找，修复丢失的数据源

#查找丢失数据源的图层

import arcpy.mapping as mapping
mxd = mapping.MapDocument(r”c:\ArcpyBook\Ch3\Crime_BrokenDataLinks.mxd”)
listBrokenDS = mapping.ListBrokenDataSources(mxd)
for layer in listBrokenDS:
    print(layer.name)

#修复丢失的数据源

import arcpy.mapping as mapping
mxd = mapping.MapDocument(r”c:\ArcpyBook\Ch3\Crime_BrokenDataLinks.mxd”)
mxd.findAndReplaceWorkspacePaths(r”C:\ArcpyBook\Ch3\Data\OldData\CityOfSanAntonio.gdb”, r”C:\ArcpyBook\Data\CityOfSanAntonio.gdb”)
mxd.saveACopy(r”C:\ArcpyBook\Ch3\Crime_DataLinksFixed.mxd”)

#替换数据源的方法

import arcpy.mapping as mapping

#修复指定的图层数据源

import arcpy.mapping as mapping

df = mapping.ListDataFrames(mxd,”Crime”)[0]
lyr = mapping.ListLayers(mxd,”Burglary”,df)[0]
