我正在尝试使用此处找到的一些代码将多个文件添加到 MXD 文件： 如何通过 python 脚本在 ArcGIS 中添加 shapefile？

下面的代码没有返回任何错误，但是似乎没有任何 shapefile 被添加到空白 mxd 文档中。

任何有关为什么这不起作用的帮助将不胜感激。

import arcpy
import arcpy.mapping
from shutil import copyfile
from os import listdir
from os.path import isfile, join

def AddAllShapeFilesToNewMXD(source_directory):
    # Source file is the template that the will be copied to the directory with
    # All the shape files in it.
    source_file = 'M:\Ops Field Map\Blank Map.mxd'

    # Output file is the name of the file that will have the shape files added to it
    output_file = 'GPS_Map'
    rev_count = 0
    while isfile(join(source_directory, output_file + '.mxd')):
        #Make sure a unique file is created
        print ('File ' + output_file + '.mxd exists.'),
        rev_count += 1
        output_file = output_file + '_rev' + str(rev_count)
        print ('Trying ' + output_file + '.mxd ...')

    # Create the destination file. This is the file the shape files are added to
    destination_file = join(source_directory, output_file + '.mxd')
    copyfile(source_file, destination_file)
    print 'MXD file created: ' + destination_file

    # Get the map doccument
    mxd = arcpy.mapping.MapDocument(destination_file)
    # Get the data frame
    data_frame = arcpy.mapping.ListDataFrames(mxd, "*")[0]

    # Get a list of all the shape files
    shp_files = [ f for f in listdir(source_directory) if isfile(join(source_directory, f)) and f.endswith('.shp') ]

    # Add all the shapefiles to the mxd file
    for s in shp_files:
        new_layer_full_path = join(source_directory, s)
        new_layer = arcpy.mapping.Layer(new_layer_full_path)
        arcpy.mapping.AddLayer(data_frame, new_layer, "BOTTOM")
        print 'Layer added ' + new_layer_full_path
        del new_layer

    return True

directory = 'C:\Users\gps\Desktop\dd test'
AddAllShapeFilesToNewMXD(directory)

没有文件很难知道，但上面的代码可能没有给出错误但没有显示任何内容的一个原因是，对于许多 arcgis 地图显示操作，您必须确保“添加结果”的 arcgis 地理处理选项地理处理>地理处理选项下的显示'的地理处理操作已打开。

可能是您遗漏了这两条重要的线：

arcpy.RefreshActiveView()
arcpy.RefreshTOC()

看起来您快到了，如果您的代码在活动会话中运行，Lucas 和BelowZero 都提供了很好的建议。如果它正在创建一个 *.mxd 供以后使用，我看不到结果的保存位置。这是一些更简单的示例代码，请注意最后一行：

mxd = arcpy.mapping.MapDocument(srcdir+'/data_bin/Untitled.mxd')
data_frame = arcpy.mapping.ListDataFrames(mxd)[0]
mxd.activeView = data_frame.name

flowlinesLyr=arcpy.mapping.Layer('..\\NHDPlus\\nhdflowline_en')
flowlinesLyr.name='NHDPlus Flowlines'
arcpy.mapping.AddLayer (data_frame, flowlinesLyr,'TOP')

gagesEventLyr=arcpy.mapping.Layer('..\\NHDPlus\\StreamGageEvent')
gagesEventLyr.name='Original stream gage locations'
arcpy.mapping.AddLayer (data_frame, gagesEventLyr,'TOP')

mxd.saveACopy(datadir+'\NHDPlus'+Region+'_Gage_QAQC.mxd')
