使用arcpy获取简单的矢量数据信息

以往在使用ArcEngine获取一些要素类的信息时会显得比较麻烦，要安装一系列的IDE才能运行。现在arcpy提供了很多方便的方式，让我们简单的获取这些信息。
import arcpy

from arcpy import env

env.workspace=r”E:services行政图行政区划图mdb.mdb”
cur=arcpy.SearchCursor(“地级市”)
for row in cur:

aa=row.getValue(“name”)

print geo.crosses(geo)

print geo.pointCount

geo=row.shape

print geo.type

print str(geo.area)+”平方米”

X= geo.extent.XMax

x= geo.extent.XMin

Y= geo.extent.YMax

y= geo.extent.YMin

print “Feature Extent XMax:%f,XMin:%f,YMax:%f,YMin:%f

name = %s”%(X,x,Y,y,aa)

这一段简单代码可以获得要素的很多信息，运行结果如下：
