GIS技术在水上加油站信息可视化管理中的应用

针对传统管理信息系统只能以纯粹的数据表格、窗体和简单的曲线向管理者和使用者反映系统中实体信息的弱点,将地理信息系统技术应用于水上加油站信息的可视化管理和统计分析,对水上加油站地理分布、吨位、数量、种类等重要信息进行地理信息系统转化和管理,以专题地图和统计图的可视化形式再现这些实体信息,并对其进行大量的对比分析.绘制地理信息系统矢量地图,并建立水上加油站地理位置图,同时生成原始数据表;运用SQL查询和选择、制作统计图、创建专题地图等功能,对信息进行提取、统计、分析,最终实现结果可视化.

Application of GIS technology in the visible information administration at the filling station on the water

To overcome the weakness of MIS which can only reflect the information to the manager and user in the datasheets,forms and simple curve,this paper used GIS into the visible administration and analysis of the filling stations on the water in Guangdong province.The information published by Guangdong maritime office including the geographic distribution,the tonnages,the quantities and the categories,etc.has been turned into GIS and managed thereby.The information was expressed by the visible forms of thematic map and statistics,and analyzed contrastively. The vector map of GIS was protracted,the local map of the filling station on the water fixed,and the original datasheets created at the same time;By using the function including,SQL demand and select,thematic map,new graph window and so on,to pick-up,count and analyze the information,finally the visible expression of the results become true.
