【摘要】 以地理信息系统(GIS)为技术支持,结合污水管网管理的实际需求,在VB环境下利用GeoMap控件进行二次开发,建立了污水管网地理信息系统。该系统充分发挥了GIS对空间、属性数据的编辑、管理、显示和查询的功能,并实现了在GIS环境下对污水管网流量的计算和水质的分析功能。更多还原

【Abstract】 Under VB environment, taking geographic information system (GIS) as technical support, incorporating with the actual requirement of sewage network management and the GeoMap control device, the secondary exploration was carried out to build GIS of sewage network. This system developed the functions of space, compilation, management and inquiry of the attribute data and could fulfill the functions of calculation and analysis of water quality of the flow of sewage network by GIS.更多还原
