Python動態重新整理kml

      以下小段代碼達到的效果是kml利用networklink不斷去執行伺服器上的phython代碼，動態改變點的經緯度座標。

首先在Internet資訊服務下預設網站下建立虛擬目錄，然後在該目錄下的“虛擬目錄”選項卡中建立應用程式，再點擊“配置”，進入“應用程式配置”，點擊添加（如），最後確定。

 

 

在該目錄的資源管理員下建立randomPlacemark.py檔案，代碼如下：

 

#!C:/Python25/python.exe#!以上更改為自己的python安裝路徑

import random

latitude = random.randrange(-90, 90)
longitude = random.randrange(-180, 180)
kml = (
'<?xml version="1.0" encoding="UTF-8"?>\n'
'<kml xmlns="http://www.opengis.net/kml/2.2">\n'
'<Placemark>\n'
'<name>Random Placemark</name>\n'
'<Point>\n'
'<coordinates>%d,%d</coordinates>\n'
'</Point>\n'
'</Placemark>\n'
'</kml>'
   ) %(longitude, latitude)
print 'Content-Type: application/vnd.google-earth.kml+xml\n'
print kml

 

然後建立檔案test.kml

<?xml version="1.0" encoding="UTF-8"?>
<kml xmlns="http://www.opengis.net/kml/2.2">
