2. Most enterprise data is stored in non-spatial enabled systems Non-spatial business systems: administrative, research, environmental enterprise-wide systems You need thematic maps showing the spatial relations Multi stake holder, watershed-wide management plans require a common architecture for coordination Non-spatial business systems: administrative, research, environmental enterprise-wide systems You need thematic maps showing the spatial relations Multi stake holder, watershed-wide management plans require a common architecture for coordination

9. 8 Pesticide Risk Assessments The EPA Office of Pesticide Programs is exploring the use of the NHDPlus and value-added attributes in a variety of applications related to pesticide risk assessments. In this example, NHD navigation tools are combined with the NLCD and NHD catchments to estimate the direct and indirect effects of agricultural pesticide use on endangered aquatic species.

10. 9 Assessing Recovery Potential of Impaired Waters Recovery potential: the likelihood of an impaired water to re-attain Water Quality Standards, given its ecological capacity to regain lost functions, its exposure to stressors, and its social context. Opportunity to consider landscape factors related to recovery potential within drainage areas and stream corridors, using GIS. (norton.douglas@epa.gov)
