Abstract

The National Agricultural Decision Support System (NADSS) is a joint project with the U.S. Department of Agriculture and the University of Nebraska-Lincoln. The initial focus of the NADSS project is to improve the quality and accessibility of drought related knowledge, information, and data for drought risk management. At the core of the NADSS project is a software architecture for distributed geospatial decision support systems that consists of four distributed layers: the data layer, the information layer, the knowledge layer, and the presentation layer. This work presents that architecture as well as the benefits and impact of the architecture and the NADSS project.
