1 前言水利规划工作需要处理的信息量往往巨大而复杂,不仅涉及水利行业内的众多数据,而且也需要利用其它行业的有关数据(如基础地形、路网、城镇规划等资料)。如何对这些数据进行科学、合理和高效的调用、查询、处理和分析,是提高规划效率、改进规划质量、提升规划水平一个亟需解决的问题,也是发展水利规划信息化、建设“数字水利”的重要内容之一。针对水利规划的上述工作要求,GIS软件是比较
1 Introduction The amount of information to be processed in water conservancy planning work is often huge and complex. It involves not only the numerous data in the water conservancy sector but also the relevant data in other industries (such as basic topography, road network and town planning). How to call, query, process and analyze these data scientifically, reasonably and efficiently is an urgent problem that needs to be solved in order to improve the planning efficiency, improve the quality of planning and upgrade the planning level. It is also necessary to develop information technology for water resources planning and construction of “digital water conservancy ”One of the important content. For the above water conservancy planning requirements, GIS software is more
