Geospatial Research, Analysis, and Services Program (GRASP)
Use Geographic Information System (GIS) to:
• identify potentially susceptible populations that live near hazardous substances waste sites or emergency events
• characterize cases, affected populations, and contamination
• analyze relationships between geographic features.
Ad hoc geospatial analysis of road networks data in conjunction with school construction data
Moderately dependent on currency and spatial accuracy of polyline (roads) and point (schools) data. Locational errors in excess of ~25 meters for either feature type will likely result in schools not being captured in 150 meter selection buffer.
