GIS学习 Geoserver使用添加、删除、查询地图中的POI

geoserverwfs:Querywfs:Deletewfs:Updatewfs:Insert 

   在geoserver自定义的地图中通过geoserver wfs 查询，删除，添加相关的POI。

相关操作的格式如下：

查询

<wfs:GetFeature service="WFS" version="1.0.0"  
       outputFormat="GML2"  
       xmlns:opengis="http://www.cetusOpengis.com"  
       xmlns:wfs="http://www.opengis.net/wfs"
