GIS学习 Geoserver使用添加、删除、查询地图中的POI

geoserver wfs:Query wfs:Delete wfs:Update wfs: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"

       xsi:schemaLocation="http://www.opengis.net/wfs   http://schemas.opengis.net/wfs/1.0.0/WFS-basic.xsd">
       <wfs:Query typeName="opengis:qqy">
      <ogc:Filter>
      <ogc:PropertyIsEqualTo>
      <ogc:PropertyName>status</ogc:PropertyName>

      </ogc:PropertyIsEqualTo>
     </ogc:Filter>
       </wfs:Query>
    </wfs:GetFeature>;

添加
