WebGIS的企业级解决方案探讨

互联网(Internet)的出现极大的改变了人们的思维方式和行为模式,成功地促成了大量传统行业向新经济行业的转变。传统的地理信息系统(GIS)与互联网的结合,借用网络技术发展的最新成果,解决长期困绕GIS行业的专业性太强、庞大、封闭和低效等一系列问题,必将带动GIS在技术层面

Thinking in Enterprise Architecture of Web GIS Applications

With the appearance of Internet promotes GIS on both technical aspect and applied aspect .traditional GIS encounters huge blocks on Internet platform. In the field of computer .Distributed Computing technology has seen fast progress with three industrial standards. And on GIS field,openGIS Consortium has drawn a series of specifications, which,combining with the three standards,provides enterprise GIS application with foundamental facilities. The authors firstly illustrate the architectures with three models-thin clent,medium client and thick client,then present a mixed model which transfers both vector and raster data between client side and server side with the advantage of high interactivity in clinet and medium data transfer. Afterward,the authors give two enterprise schema based on two standards: COM + and EJB. Finally,the authors list some key technologies which will affect the future WebGIS-openGIS, XML, Windows. net, CORE A, EJB, etc.
