Web geographic information system decision support system for irrigation water management: a review

This paper reviews literatures on Web geographic information system decision support system (Web GIS DSS), its development, and applications in irrigation water management. The purpose is to summarize and synthesize the most useful approach used in developing web applications for irrigation water management. It encompassed varieties of reports and publications for wider understanding of the topic. The review provides the concept, methodologies, and various uses of the applications. Critical analysis on the choice of structural framework and Graphical User Interface has been discussed. Among problems encountered during system development were: data management, security, user needs, etc. The use of Web GIS DSS is gaining more attention from Irrigation Engineers, System Developers, and Cartographers. Web GIS and especially the real-time capability can be of importance in solving many problems regarding irrigation water management. When system is well design, it can be safe, cheap, and maximize profit of any business. The future of development and application of web GIS applications were well discussed by presenting the latest technology in the systems development. There is need for standardization of some aspect of methodologies issues concerning information security and customization to ensure flexibility and viability. The web GIS is simply the future of many spatial transactions.
