ABSTRACT

ABSTRACT: According to the demand of Linyi Municipal Water Conservancy Bureau, Linyi municipal groundwater resources management information system based on GIS is designed and implemented. An algorithm for auto-generating of groundwater isoline based on TIN and the same color weighted minimum distance is proposed, and the hydraulic characteristics of the contour lines produced by the algorithm are consistent with actual situation. The query operation between map and text mutually based on information mining technology which makes the spatial features integrate with the parameters of groundwater resources, is implemented. The management information system has been used in Linyi Water Conservancy Bureau and achieved good economic and social benefits.
