WMS学习笔记：2.WMS解析

 WMS 定义了三个操作，分别是：GetCapabilities，GetMap和GetFeatureInfo。其中，GetFeatureInfo是可选的。本条款规定了在超文本传输协议（HTTP）分布式计算平台（DCP）上，这些WMS操作的执行和使用。

1.必选操作GetCapabilities的目的是为了获得服务元数据，服务元数据是一些可以机读（或者人读）的关于服务器信息内容以及可接收的请求参数值的描述。

WMS服务元数据示例：

  <ows:Title>Global 30 Second Elevationsows:Title> 
  <ows:Abstract>GTOPO30 is a global digital elevation model (DEM) resulting from a collaborative effort led by the staff at the U.S. Geological Survey's EROS Data Center in Sioux Falls, South Dakota. Elevations in GTOPO30 are regularly spaced at 30-arc seconds (approximately 1 kilometer). GTOPO30 was developed to meet the needs of the geospatial data user community for regional and continental scale topographic data.ows:Abstract>

2.GetMap操作返回一幅地图。当接收到一个GetMap请求时，WMS应当满足请求或产生服务异常。

3.GetFeatureInfo是一个可选的操作。它仅仅支持那些定义或继承了属性queryable=“1”（真）的那些图层。对于其他图层，客户不能发送GetFeatureInfo请求。如果一个WMS接到一个它不支持的GetFeatureInfo请求，则应该以一个适当格式化的服务异常（XML）响应（code =OperationNotSupported）。

GetFeatureInfo操作用于向WMS的客户提供关于此前地图请求返回的地图图像中要素的更多信息。对于GetFeatureInfo来说，规范的应用情形是用户看到了地图请求的响应，然后用户选择该地图上的一点（I, J），并据其查询更多的信息。基本操作可以使客户确定所要查询的像元、查询的是哪个（些）图层以及返回信息需要何种格式。由于WMS协议是无状态的（stateless），通过包含原来的GetMap请求中几乎全部参数（除VERSION和REQUEST外），GetFeatureInfo请求向WMS指明用户正在浏览的地图。根据GetMap请求中的空间的前后关系信息（BBOX, SRS, WIDTH, HEIGHT）以及用户选择的I,J位置，WMS就可以（能）返回关于该位置更多的信息。
