GetCapabilities 响应

GetCapabilities 操作返回包含服务级别的元数据信息简要描述的 XML 文档。此文档主要由四个部分组成：

元素名称	描述
ServiceIdentification	服务简介。
ServiceProvider	服务提供者。即对服务提供者基本信息的描述。
OperationsMetadata	操作元数据信息。描述服务所能提供的操作。
Filter_Capabilities	过滤运算符的元数据。描述用于过滤的运算符。

Filter_Capabilities 部分用于描述当前服务所提供的过滤操作类型，主要包含以下部分：

元素名称	描述
Spatial_Capabilities	包括支持的空间操作运算、几何操作运算列表。
Scalar_Capabilities	标量运算操作元数据，包括支持的比较运算列表。

其中 Spatial_Capabilities 部分用于描述支持的空间操作符，由以下部分构成：

元素名称	是否必须	描述
GeometryOperands	是	几何运算对象，目前支持 Envelope 用于指定地理范围。
SpatialOperators	是	空间操作，目前支持 Within,Intersects,Disjoint。

其中 Scalar_Capabilities 部分用于列出支持的逻辑运算和比较运算，由以下部分构成：

元素名称	是否必须	描述
LogicalOperators	否	逻辑运算符。支持 And,Or,Not。
ComparisonOperators	是	比较运算符。支持 Between,EqualTo，GreaterThan，GreaterThanEqualTo，LessThan，LessThanEqualTo，Like，NotEqualTo。
