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。
You can write XML documents better by using a professional XML editor. XML refers to extensible markup language You can use simple XML editors such as notepad to create or edit XML files. However, when you start using XML, you will soon find that it can edit XML files better using a professional XML editor.

You cannot determine the type of document you are editing, so it cannot assist you in your work. Today, XML is a very important technology, and development projects are using these XML-based technologies: Define the structure and data type of XML with XML Schema Using XSLT to transform XML data Using SOAP to exchange XML data between applications Using WSDL to describe network services Using RDF to describe network resources Using XPath and XQuery to access XML data Use SMIL to define graphics To be able to write error-free XML documents, you need a smart XML editor! A professional XML editor will help you write error-free XML documents, validate XML against some kind of DTD or schema, and force you to create legitimate XML structures. The XML editor should have the following capabilities: Automatically add an end tag to the start tag Force you to write a legitimate XML Verify XML against DTD Verify XML against Schema Colorize the code for your XML syntaxXML is text-based ¶
