Design of Spatial Decision Support Tool

To support the experts and decision makers with the information on cumulative environmental exposure the research was carried out to design a spatial decision support tool for understanding cumulative environmental exposure (SDSTCE). Online questionnaire with the experts was conducted to collect primary data on ¿Importance of Visualization, Functions and Tools in Understanding Cumulative Environmental Effects in Spatial Decision Support System (SDST)¿.The survey involved experts from public health, environment, urban planning together with authors and professionals dealing with DSS. The ROMC design approach and the use case approach were used to design the SDSTCE. The design was operationalized as SDSTCE EnL in Community Viz by using secondary data from Dortmund. It is capable of producing index maps, graphs; which is interactive in nature. It is also capable to assess the area and population exposed to cumulative environmental stressors. Furthermore, it is also capable to overlay different layers over index map for the analysis.The index was used to understand the geographic extent of cumulative environmental stressors.
