11
Methodology Reality
  • Winthrop
  • Coastal Storms
  • Flooding
  • Elderly residents
  • Roadways
  • Shelters location and accessibility
  • Evacuation routes - existing
  • Elevation
  • Storm Surge

12
Spatial Analysis
  • Answering What if scenarios
  • Mapping where things are
  • Mapping density
  • Finding whats near by
  • Patterns
  • Normative Process
  • Develop or prescribe new or better designs (e.g.
    evacuation route)

13
My Data Model Objective
  • Choose the best route of egress for evacuation
    route,
  • Identify the area of residency of elderly
    population,
  • Within Winthrop Identify shelter in place and
    critical evacuation areas,
  • Outside Winthrop Identify shelters

14
Data Collection
