珠江流域水情会商系统近日建成并投入试运行。该系统是珠江委水文局和南京水文水资源研究所经过近一年的合作开发成功的。系统由地理信息模块、数据库模块、信息显示模块、总控模块组成,具有电子地图操作、超警显示、单站查询、多站查询、雨量等值线、面雨量统计等功能,以大型网络数据库为基础,利用GIS技术处理和显示有关河流水系、测站等地理信息,服务器数据库采用网络数据库SYBASE,客户机与数据库连接采用开放数据库连接ODBC技术,数据库数据查询采用结构化查询语言(SOL)实现,图形操作采用Mapinfo地理信息处理系统 Pearl River Basin Water Conservancy Business System recently completed and put into trial operation. The system is Pearl River Commission Hydrographic Bureau and Nanjing Institute of Hydrology and Water Resources after nearly a year of successful cooperation and development. The system is composed of geographic information module, database module, information display module and total control module. It has such functions as electronic map operation, alarm display, single station inquiry, multi-station inquiry, rainfall contour and surface rainfall statistics. Based on the use of GIS technology to process and display the river water system, station and other geographic information, server database using network database SYBASE, client and database connection using open database connection ODBC technology, database data query using Structured Query Language (SOL) , Graphics operations using Mapinfo geographic information processing system
