空间地理信息

• In this paper , mapinfo profession 6 . 0 was applied to build and manage space geographical information ; mapinfo mapx4 . 5 was used as a activex control to model and describe the air diffusing area of the spilled gas chemical , by the technology of ole , made used of the integrating environment of visual basic 6 . 0 , we finished developing research on the air diffusion system of spilled gas chemicals based on gis . the system can dynamically show the diffusion range of spilled gas chemicals on computer screen after inputting necessary parameters . the paper include 7 chapters
  我们是以mapinfoprofession6 . 0作为空间地理信息建立和管理工具， visualbasic6 . 0作为系统用户界面开发与计算模块编程工具， access2000作为有关数据库开发与管理工具， mapinfomapx4 . 5地理信息系统地图控件作为计算机模拟显示控件，通过ole技术，在vb的集成环境下进行“基于gis的水运气体化学晶泄漏大气扩散模拟系统”的开发创建。
