arcpy批处理示例

示例1：对一个gdb数据库进行了遍历，并对遍历的每一个要素类图层进行要素修复

import arcpy
#读取文件
arcpy.env.workspace = r"C:\Users\Administrator\Desktop\H48G026039.gdb"
#取出要素类
fcs = arcpy.ListFeatureClasses()
fcCount = len(fcs)
for fc in fcs: #遍历要素类   arcpy.RepairGeometry_management(fc)print fc
print fcCount

示例2：对一个文件夹下的mxd文件进行遍历，并导出为jpg文件

import arcpy, os, time
path = r'D:\可行性分析' #文件夹路径
res = 100
print '程序开始：' + str(time.ctime())
for afile in os.listdir(path): #遍历文件夹里的文件if afile[-3:].lower() == 'mxd': #文件名后三位为mxdmxd = arcpy.mapping.MapDocument(os.path.join(path,afile))arcpy.mapping.ExportToJPEG(mxd, os.path.join(path,afile[:-3] + 'jpg'), resolution = res)del mxd
print '程序结束：' + str(time.ctime())

地理处理工具

编写.py脚本，并新建工具箱后即可使用

import sys
reload(sys)
sys.setdefaultencoding('utf-8') #设置编码
import arcpy
#获取工作空间
path = arcpy.GetParameter(0) #获取参数
arcpy.env.workspace = path
#获取该目录下的要素集
fcs = arcpy.ListFeatureClasses()
fcCount = len(fcs)
for fc in fcs: #遍历要素集#设置过程中提示语arcpy.SetProgressorLabel("修复要素类:" + fc +"...")  #要素修复arcpy.RepairGeometry_management(fc)print fc
print fcCount

要素属性操作

ArcPy对几何对象属性的操作，包括查询、添加、更改、删除
原文：http://blog.csdn.net/sprintwater/article/details/48858427

import time,os
import arcpy  print '程序开始：' + str(time.ctime())
arcpy.env.workspace = r"C:\Users\ljb\Desktop\高程数据"
#输入要素
inFeatures = "TERLK_LN.shp"
#添加一个字段用来标记高程是否可以整除10
fieldName1 = "Mark"
fieldPrecision = 2
fieldAlias = "整除10标记"  #列出所有字段
fieldObjList = arcpy.ListFields(inFeatures)
# Create an empty list that will be populated with field names
fieldNameList = []
# For each field in the object list, add the field name to the
#  name list.  If the field is required, exclude it, to prevent errors
for field in fieldObjList:  if not field.required:  fieldNameList.append(field.name)
print fieldNameList
if fieldName1 in fieldNameList:  arcpy.DeleteField_management(inFeatures, fieldName1)  print"删除已有字段"  #添加字段函数
arcpy.AddField_management(inFeatures, fieldName1, "LONG", fieldPrecision, "", "",  fieldAlias, "NULLABLE")  field1 = "Elev"
field2 = "Mark"  #更新查询
cursor = arcpy.UpdateCursor(inFeatures)
for row in cursor:  # field2 will be equal to field1 multiplied by 3.0  if((int)(row.getValue(field1))%10 == 0):  row.setValue(field2, 1)  else:  row.setValue(field2, 0)  cursor.updateRow(row)
print '程序结束：' + str(time.ctime())

复制数据库

import arcpy
from arcpy import env
import os
# Allow for the overwriting of file geodatabases, if they already exist #
env.overwriteOutput = True
# Set workspace to folder containing personal geodatabases #
env.workspace = arcpy.GetParameterAsText(0)
# Identify personal geodatabases #
for pgdb in arcpy.ListWorkspaces("*", "FileGDB"):  # Set workspace to current personal geodatabase#  print pgdb  env.workspace = pgdb  # Create file geodatabase based on personal geodatabase#  fgdb = pgdb[:-4] + "2.gdb"  arcpy.CreateFileGDB_management(os.path.dirname(fgdb), os.path.basename(fgdb))  # Identify feature classes and copy to file gdb     #  for fc in arcpy.ListFeatureClasses():  print "Copying feature class " + fc + " to " + fgdb  arcpy.Copy_management(fc, fgdb + os.sep + fc)  # Identify tables and copy to file gdb #  for table in arcpy.ListTables():  print "Copying table " + table + " to " + fgdb  arcpy.Copy_management(table, fgdb + os.sep + table)  # Identify datasets and copy to file gdb  # Copy will include contents of datasets#  for dataset in arcpy.ListDatasets():  print "Copying dataset " + dataset + " to " + fgdb  arcpy.Copy_management(dataset, fgdb + os.sep + dataset)

处理Excel数据生成多边形

Python对Excel读写xlrd库
原文：http://blog.csdn.net/sprintwater/article/details/40052675

 import xlrd  import xlwt  import arcpy  xlsPath = r"C:\Users\Administrator\Desktop\Polygon.xls"  data = xlrd.open_workbook(xlsPath)  table = data.sheets()[0]#通过索引顺序获取  cols = table.col_values(5)  nrows = table.nrows  point = arcpy.Point()  array = arcpy.Array()  polygonGeometryList = []  for i in range(1,nrows):  str = table.cell(i,5).value  points = str.split(u'；')  for j in points:  xy = j.split(',')  print xy[0]  print xy[1]  print '\n'  point.X = float(xy[0]);point.Y = float(xy[1])  array.add(point)  polygon = arcpy.Polygon(array)  polygonGeometryList.append(polygon)  array.removeAll()  arcpy.CopyFeatures_management(polygonGeometryList, "d:\\polygon.shp")  print 'over'

批量将hdf数据转换成tif数据

arcpy.env.overwriteOupt = 1
arcpy.CheckOutExtension("Spatial")
inPath = r"D:/HDF/"
outPath = r"D:/Output"
env.workspace = inPath
arcpy.env.scratchWorkspace = inPath
hdfList = arcpy.ListRaster('*', 'HDF')
for hdf in hdfList:name = hdf[8:16] + ".tif"data = arcpy.ExtractSubDataset_management(hdf, name, "1")
