Geospatial Analysis
Geospatial Analysis :
Analysis of risk information by distance, area, volume or any other spatial characteristic within geographic boundaries through GIS and hazard mapping techniques. The benefits of the technique are the identification of hazards and dangerous locations at varying scales from local (less than 100,000 km2), through regional (100,000 to 10 million km2) to continental (10 to 100 million km2) and a view of risk not only from a singular hazard point of view, but also from an orientation to the relative levels of exposure. The limitations of the technique are the same as those for GIS techniques with the added requirement for well-defined geographic boundaries (e.g., counties, municipalities, and health districts).
