In some projects charged by our lab such as national 863 project - " crop planting management components based on weather analyse ", anhui provincial 95 key project - " agricultural meteorology disaster evaluation system base on gis in anhui province " and the project " small coal mine security management and decision system based on gis in anhui province ", this paper combines the theory and arithmetic of rough set with gis and data mining in idss, investiges the application of rough set theory to precision analysis of attribute data and logical operation in gis, analyzes the logical operation based on rough set ( logical union, logical intersection, logical complement, mixed logical operation etc. ), so that it can give a method y to research the gis attribute data and the uncertainty of attribute data after superposition operator, so as to express the roughness and illegibility of attribute data more accurately
在完成試驗室所承擔的國家863項目「基於氣象分析的農作物種植管理軟構件」 、省95攻關項目「基於gis的安徽省重大農業氣象災害測評系統」和「基於gis的安徽省小煤礦安全管理決策系統」等項目中，將粗糙集理論和演算法與gis 、智能決策系統中的知識發現等相結合，對粗糙集理論在gis屬性數據和邏輯運算精度分析中的應用情況進行了研究，分析了基於粗集的gis邏輯運算（邏輯並、邏輯交、邏輯補、混合邏輯等） ，從而為研究gis屬性數據及其疊加運算后屬性數據的不確定性提供了一種方法，能比較準確地表達屬性數據的模糊性和粗糙性。 -
Based on the ana1yse of the way of the water pipe network ’ s management and the difficult problem which exist in the course of running water pipe network it presents the collectivity project of the city service pipe network geography information manage system and estab1ish the waterpipe network ’ s basic data - base, and conform afresh the network data by the mode of data - base organization. then on the base of it, open out the water pipe networks graphics show and edit, hydraulic simulation module, disposal accident module and data query andanalyse module and set up the geography information system. it will exert the network ’ s data - base and computer effect on the city water management
在對目前給水管網管理方式以及管理過程中碰到的問題進行分析的基礎上，給出了城市給水管網地理信息管理系統的總體方案和詳細設計，同時建立了給水管網基礎數據庫，依照數據庫的組織方式對管網數據進行管理、編輯和分析，並在此基礎上，開發了城市給水管網圖形顯示、圖形編輯、水力模擬、管網事故處理、管網數據查詢分析和管網數據專題圖等功能模塊，建立了城市給水管網地理信息系統，以充分發揮管網數據和計算機技術在城市供水管理中的作用。
