最近几年来，地理信息系统无论是在理论上还是应用上都处在一个飞速发展的阶段。 GIS被应用于多个领域的建模和决策支持，如城市管理、区划、环境整治等等，地理信息成为信息时代重要的组成部分之一； “数字地球”概念的提出，更进一步推动了作为其技术支撑的GIS的发展。 与此同时，一些学者致力于相关的理论研究，如空间感知、空间数据误差、空间关系的形式化等等。 这恰好说明了地理信息系统作为应用技术和学科的两个方面，并且这两个方面构成了相互促进的发展过程。
The Envelope element of the mandatory SOAP is the root element of the SOAP message. The required Envelope element of SOAP is the root element of the SOAP message. It defines an XML document as an SOAP message. The SOAP message must have an Envelope element associated with the namespace “ http://www.w3.org/2001/12/soap-envelope ”.” If a different namespace is used, the application will have an error and discard the message. The encodingStyle property of SOAP is used to define the data types used in the document. This attribute can appear in any SOAP element and is applied to the contents of the element and to all child elements of the element. There is no default encoding for SOAP messages. 3.4.1.
