基于GIS模式的数据仓专题图研究

Research on Thematic Cartography Prospect Based on GIS Data Warehouse

针对基于GIS的BTEX油气化探数据仓地质专题图制作系统进行研究,分析了基于自动化制图理念的数据流,提出了系统的总体构架及基于国家标准的地质符号库,并根据油田地质成果图规范开发了BTEX油气化探数据仓数据挖掘成果图的制图模板。将该系统应用于渤中凹陷的BTEX数据综合评价图的制作,结果表明该软件具有较好的人机交互性和扩展性,在满足BTEX油气化探数据仓的处理结果专题地图的制作与成果展示的基础上,能够提高BTEX油气化探地质专题图的制图效率。

This paper presents the research studies of thematic cartography for BTEX data warehouse of oil-gas geochemical prospect based on GIS,which includes geologic symbol library in common use,saving and extracting spatial and attribute data in Data Warehouse,automatic theme filled and also the function for geologic thematic map＇s design and export.The result of the system test indicates that the system has commendably carried out the primary design,for it can effectively exhibit the result of BTEX Data Warehouse of Oil-Gas Geochemical Prospecting and has a good interaction capability between users and computer.
