Construction of a Decision Support System Based on GP Services, Using a Warning–Judgment Module as an Example

Abstract

Decision-making departments need more detailed and timely data in order to meet the needs of emergency response. Sichuan province is an area that frequently suffers natural disasters, and many disasters are caused by rainfall. This study establishes a decision support system (DSS) based on geoprocessing (GP) services, which can locate the region that overran the rainfall threshold and provide the population or property analysis, query, map plot, and path analysis functions. Most of the functions of the system are developed on the basis of geoprocessing services. This paper uses the warning-judgment module as an example to introduce the structure and function of the DSS system. The system satisfies the demands of real-time data acquisition, calculation, analysis, and presentation.

Sistemas de Suporte à Decisão Espacial e Aplicações

“…Na área de monitoramento de desastres, Sang et al [23] construíram um sistema para localizar em tempo real regiões na província de Sishuan, na China, que ultrapassem os limites de precipitação. Este SDSS é capaz de fornecer mapas e previsões de inundações com base em históricos anteriores.…”
