Geoserver WPS时间和边界框过滤

Question

我想创建一个有时间和边界框过滤的wps执行。但是，Geoserver返回“参数cropShape缺失”。我该如何解决这个问题？感谢您在WPS请求正文下面的help.In。对于请求"http://serverName:port/geoserver/wps?service=WPS“

Answer 1

对DescribeProcess响应的快速检查显示，该过程接受两个输入：

<Input maxOccurs="1" minOccurs="1">
    <ows:Identifier>coverage</ows:Identifier>
    <ows:Title>coverage</ows:Title>
    <ows:Abstract>Input raster</ows:Abstract>
    <ComplexData>
       ...

和

<Input maxOccurs="1" minOccurs="1">
    <ows:Identifier>cropShape</ows:Identifier>
    <ows:Title>cropShape</ows:Title>
    <ows:Abstract>Geometry used to crop the raster</ows:Abstract>
    <ComplexData>
      ...

但是，您只提供了一个输入，因此GeoServer指出第二个输入(cropShape)是必需的，而您没有提供它。需要一个多边形来指定要裁剪到的形状。

如果你想要的只是从WCS中提取一个“多维数据集”，那么你根本不需要WPS。
