geoserver wfs空间查询

在GeoServer中，可以通过使用Web Feature Service (WFS)来进行空间查询。WFS是一种基于网络的服务，允许用户查询和获取地理空间数据。您可以使用WFS来执行点查询和线查询。

对于点查询，您可以使用以下请求URL进行查询：
http://***:8060/geoserver/**/ows?service=WFS&request=GetFeature&version=1.0.0&typeName=图层服务名称&maxFeatures=2000&outputFormat=json&filter=
<Filter xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">
<Intersects>
<PropertyName>GEOM</PropertyName>
<gml:Point>
<gml:coordinates>113.8037,34.43554</gml:coordinates>
</gml:Point>
</Intersects>
</Filter>

而对于线查询，您可以使用以下请求URL进行查询：
http://***:8060/geoserver/**/ows?service=WFS&request=GetFeature&version=1.0.0&typeName=图层服务名称&maxFeatures=2000&outputFormat=json&filter=
<Filter xmlns="http://www.opengis.net/ogc" xmlns:gml="http://www.opengis.net/gml">
<Within>
<PropertyName>GEOM</PropertyName>
<gml:LineString>
<gml:coordinates>113.763,34.435 113.763,34.5 113.844,34.5 113.844,34.435</gml:coordinates>
</gml:LineString>
</Within>
</Filter>

在上述URL中，您需要替换“***”为您的GeoServer服务器地址，替换“**”为您的GeoServer工作区名称，替换“图层服务名称”为您要查询的图层的名称。

请注意，上述URL请求将返回JSON格式的查询结果。您也可以根据需要调整输出格式。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
