In recent years, the Yellow River Conservancy Commission ( hereinafter referred to as the Yellow River Conservancy ) based on Web GIS (MapXtreme) and map services middleware to build a the YRCC map service platform . In this paper, on the basis of this platform , Internet / Intranet version of the Yellow River downstream engineering conditions dangerous situation in consultation system \The system is based on the Internet , a combination of computer science and geographic information systems , the use of middleware technology , developed using the Java language . The paper gives the basic framework of the system , the logical structure and functional structure , database design , and systems related to technology research and discussion , the last case analysis to the realization of the entire system . The system is the system of flood control and application oriented combination of the modern network conditions and existing technology development strength and development and construction committee, the provincial , municipal and county levels . Currently , the system has been applied to the actual flood prevention work , the basic realization of the oriented \Finally, in Chapter VI gives the main innovation of the system and the need to be perfected , the technical indicators to improve flood control consultation system to provide more comprehensive information to support engineering conditions for future the danger consultation work .
