Description: 

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.

Supplier: 
Centers for Disease Control and Prevention, Agency for Toxic Substances and Disease Registry
Data Years Available: 
2005 to present
Periodicity: 
Periodic
Mode of Collection: 
Ad hoc geospatial analysis of road networks data in conjunction with school construction data
Selected Content: 
N/A
Population Covered: 
N/A
Methodology: 

Ad hoc geospatial analysis of road networks data in conjunction with school construction data

Response Rates and Sample Size: 
N/A
Interpretation Issues: 

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.
