ArcGIS python代码将路径更改为所有子目录的相对路径

Question

对python很陌生，但在大学有一些编码经验。当我准备 GIS 项目数据库以从本地托管过渡到云托管（刚开始在家工作）时，我正在尝试找到一种方法将每个 mxd 文件中的路径从绝对更改为相对。我发现了 2 个我认为可能有效但无法让它们一起工作的代码片段。 ArcGIS 中的代码仅适用于一个文件夹，我希望它能够在根目录中的每个子目录上运行。感谢您的帮助！

ArcGIS Python 部分

import arcpy, os

#workspace to search for MXDs
Workspace = r"c:\Temp\MXDs"
arcpy.env.workspace = Workspace

#list map documents in folder
mxdList = arcpy.ListFiles("*.mxd")

#set relative path setting for each MXD in list.
for file in mxdList:
    #set map document to change
    filePath = os.path.join(Workspace, file)
    mxd = arcpy.mapping.MapDocument(filePath)
    #set relative paths property
    mxd.relativePaths = True
    #save map doucment change
    mxd.save()

子目录代码

... from fnmatch import fnmatch
... 
... root = 'C:\\user\projects'
... pattern = "*.mxd"
... 
... for path, subdirs, files in os.walk(root):
...     for name in files:
...         if fnmatch(name, pattern)
...             mxdList = arcpy.ListFiles
...

您不需要为此任务使用fnmatch 模块。 arcpy.ListFiles('*.mxd') 函数中的通配符就足够了。不是循环通过files，而是循环通过subdirs 和os.walk(root)。

尝试以下方法：

import arcpy, os

root = r'C:\user\projects'
pattern = "*.mxd"

for path, subdirs, files in os.walk(root):
    for subdir in subdirs: # loop through each subdirectory
        fullpath = os.path.join(path, subdir)
        print('Current directory: {}'.format(fullpath))
        # set new workspace to combination of path and subdir
        arcpy.env.workspace = fullpath 
        # search in the new workspace
        mxdList = arcpy.ListFiles(pattern) 
        for file in mxdList: # apply the changes for each file
            print('Processing: {}'.format(file))
            # set map document to change
            # here the variable file should be sufficient
            mxd = arcpy.mapping.MapDocument(file) 
            # set relative paths property
            mxd.relativePaths = True
            # save map doucment change
            mxd.save()
