This paper discusses the development of a Web-based Intelligent Spatial Decision Support system that helps efficiently plan snow removal operations. The system is designed to integrate Web and geospatial analytical techniques for asset management, routing procedures and weather information to assist effective snow removal procedures. The system includes the knowledge from snow removal experts from Blackhawk County in Iowa and the cities of Cedar Falls and Waterloo, Iowa. It manages various resources efficiently by providing expert advice to assist complex decision making for efficient routing, optimal resource allocation, while monitoring live weather information. The system has been developed as a Web-based system to facilitate ubiquitous access and ease of use.
