ArcGIS中python实现地图服务的自动发布
项目的具体需求是，每天下载几张tiff图片，放在mxd文件里，然后将其发布到ArcGISServer，后来 参照网上有一篇文章，可以自动发布地图服务，但是，后来发现，现在使用的ArcGIS版本10.2.2已经放弃了原来的方式发布服务，根据ArcMap里的帮助文档，发现里面的例子还是挺多的，自己又修改了实现的代码，遇到的问题是，
con = 'C:/Users/IBM_ADMIN/AppData/Roaming/ESRI/Desktop10.2/ArcCatalog/arcgis on localhost_6080 (publisher).ags'实现方式是创建一个模板的mxd文件，每次，修改其数据源，这样图层的渲染方式不会改变，曾经想着将模板文件里的图层删掉，再添加新的图层，但，发现默认添加的tiff图层的渲染方式竟然不是ArcMap里自动添加tiff图层的渲染方式（rgb）,添加出来的图层是灰色图，python的symbol控制又比较弱，所以，改成修改数据源的方式，实现了最终的效果
下载tiff文件的代码downLoadTiff.py：
import urllib
import urllib2
import os,time
ftime=time.strftime("%Y_%m_%d", time.localtime())#2015_12_01 tiffFonderName
ftime1=time.strftime("%Y-%m-%d", time.localtime())#2015-12-01 tiffNametime
ftime='2015_12_07'
ftime1='2015-12-07'
tiffFolder='..\\..\\'+ftime
tiffNameStart='nasa-worldview-'
os.mkdir(tiffFolder)
url = 'http://9.186.62.26/weather/satellite/'#nasa-worldview-2015-11-30.tiff'
print "downloading start from http://9.186.62.26/weather/satellite/"
tiffName=tiffNameStart+ftime1+'-2.tiff'
urllib.urlretrieve(url+tiffName, tiffFolder+'\\'+tiffName)
print "downloading with urllib from "+url+tiffName
tiffName=tiffNameStart+ftime1+'-3.tiff'
urllib.urlretrieve(url+tiffName, tiffFolder+'\\'+tiffName)
print "downloading with urllib from "+url+tiffName
tiffName=tiffNameStart+ftime1+'-4.tiff'
urllib.urlretrieve(url+tiffName, tiffFolder+'\\'+tiffName)
print "downloading with urllib from "+url+tiffName
tiffName=tiffNameStart+ftime1+'.tiff'
urllib.urlretrieve(url+tiffName, tiffFolder+'\\'+tiffName)
print "downloading with urllib from "+url+tiffName
