Outline

Emergency Response Cycle

www.ready.gov

Developed countries often have preparedness plans available

www.ncdp.mailman.columbia.edu

Current Geospatial Frameworks/Initiatives

www.dpri.kyoto-u.ac.jp

www.fema.gov/hazus

www.gazi.edu.tr

Current Geospatial Frameworks/Initiatives

• Developing countries often lack the geospatial infrastructure

• Use GIS to facilitate disaster reduction through vulnerability assessment

• Use only Free and Open Source Software (FOSS) and dataCan help minimize procurement resourcesProvides agility and flexibility (no vendor lock-in)

• End result: most anyone, with some training, can identify areas and infrastructure vulnerable to earthquakes, using only freely available data and software

Motivation

Proposed Methodology5 stages:

1. Site location

2. Search for and procure data

3. Identify gaps and resolve if possible

4. Edit data to ensure compatibility

5. Perform analysis

Data ConsiderationsData Sources:Open Source Free Including Crowd-sourced

Primary Data Concerns: Quality Usability Security

Crowd-sourced proven useable:

Geocoding data project - proved to be 85% accurate

Data Considerations

Common datasets include:• Administrative boundaries and populated places• Hydrography• Topography• Land cover and land use• Utilities• Critical infrastructure• Demographic data

Disaster specific datasets for earthquakes:• Fault lines• Historical seismic activity• Soil classification

Issues with data from various sources:AccessInteroperabilityScaleAccuracyCurrencyCoordinate systemRedundancy

Issues with data from developing countriesSlow/intermittent Internet connection

• Open Source has been used with success

• Community involvement• With little training, areas and infrastructure

at risk can be identified

• Every community has it’s own specific needs

• Communities change over time
