python实现CAD批量转shp

(2015-12-08 12:20:38)

过程是先利用quickimport将cad批量导入gdb里，然后gdb转为shp；（arcgis需安装Data Interoperability）

# Import system modules

import arcpy

import os

from arcpy import env

from arcpy import interop

# Set local variables

input_cad_folder = "C:\Users\LL\Desktop\CAD"

output_gdb_folder = "C:\data"

output_folder="C:\output"

for found_file in os.listdir(input_cad_folder):

# Searches for .dwg files

if found_file.endswith(".dwg"):

print "Converting: "+found_file

input_cad_dataset = os.path.join(input_cad_folder, found_file)

print "Converting: "+input_cad_dataset

output_gdb = found_file.split(".")[0] +".gdb"

output_gdb_path = os.path.join(output_gdb_folder, output_gdb)

print "Converting: "+output_gdb_path

try:

interop.QuickImport(input_cad_dataset, output_gdb_path)

env.workspace = output_gdb_path

fcs = arcpy.ListFeatureClasses("*")

output_shp_path=output_folder+output_gdb.split(".")[0]

print "Create: "+output_shp_path

os.makedirs(output_shp_path)

for fc in fcs:

outfc = arcpy.ValidateTableName(fc)

print "Create: "+outfc

arcpy.FeatureClassToShapefile_conversion([outfc], output_shp_path)

except:

print arcpy.GetMessage()
