The objective of this paper is to introduce the Internet-GIS approach, analyse the needs and demand of the project and generate a complete Internet-GIS application based on UMN Map Server and kvwmap for flood control and socio-economic development in Mekong Delta area of Vietnam. This paper reviews and discusses the current development of Internet-GIS as well as its future, suggested Map Server and kvwmap for the development of Internet-GIS application for environmental management. The application has been developed in PHP and Java Script and databases have been created and managed by MySQL and PostgreSQL. An Internet-GIS application has been created with different functions such as: basic functions, navigation functions, layer functions, editor functions, query functions, digitizing functions, print functions, import/export functions, data management and work flow functions, collaborative work functions, advanced analysis functions, etc. The application can switch between 3 languages: English, German and Vietnamese. The authors have created a complete Internet-GIS application including geospatial database which is divided into 5 groups: Topography, Digital Elevation Model (DEM), Land use, Hydrology system, and Remote sensing data.
