With the development of information technology , computer application software evolved from stand-alone application to the CS (Client / Server) structure of the application and then BS (Browser / Server) structure of the application continues to evolve, and from which pure BS BS structure structure developed to the COM component -based distributed computing architecture to the current of Web Service -based distributed computing architecture structure . Development of computer software architecture can be described as rapid . This paper summarizes WebGIS technology , while insufficient , a new cross-platform WebService technology, and depth, detailed study of the Web Service technology and the realization of the principle of operation mechanism , as well as Web GIS technology and Web Service technology combine to produce a GIS Web Service technology . Combination of Java as an example of the Apache Tomcat server and Axis components to develop an application for other platforms and train inquiry call Web Service. Discussed in detail the Web Service Ak platform configuration , and application development to publish a series of questions . By successfully applied to the Web Service with Java and MO Java development prospects GIS system to provide users with a dynamic , visual train GIS query process. Based on Web Service technology train travel GIS query system to be able to offer passengers convenient, fast and efficient Timetable solutions, and web-based publishing system allows for a wider range of users, one can realize the value of the system itself , secondly, they can learn from the Internet user suggestions and recommendations in a timely manner to maintain and update the system . Paper work done and results achieved for the Web Service, GIS Web Service application to provide a wider range of areas can learn reference.
