HIGHLIGHTING THE USE OF GIS IN CLIMATE CHANGE
  • UWI CLIMATE CHANGE
  • JUNE, 2007

3
Overview of presentation
  • What is GIS
  • Associated tools
  • Remote Sensing
  • Global Positioning System
  • Web publishing of maps/data
  • Application at ODPEM

4
What is GIS?
  • Geographic Information Systems (GIS) is a
    spatial database management system that can
    analyze, query and display data using digitized
    maps and tables for planning and decision-making
    (Anonymous)

5
Remote Sensing
  • Remote sensing is the short or large-scale
    acquisition of information of an object or
    phenomenon, by the use of either recording or
    real-time sensing device(s) that is not in
    physical or intimate contact with the object
    (such as aircrafts, satellites).

7
Remote Sensing allows for
  • Image interpretation classification
  • Time-series image analysis
  • Drought analysis
  • Tracking of hurricanes

8
Global Positioning System
  • GPS is a satellite navigation system used to
    determine ground position (coordinates) a
    worldwide satellite navigational system formed by
    24 satellites orbiting the earth and their
    corresponding receivers on the earth.

9
GPS devices allows you to
  • Gather accurate spatial data
  • Flood extent
  • Sea level rise
  • Storm surge runup
  • Heights above sea level

10
WEB PUBLISHING
  • Web delivery of geographic data and maps.
  • Allows you to
  • Publish high-quality interactive maps that can be
    accessed by thousands of people simultaneously
    over the Internet.
  • Integrate data from multiple sources (Internet or
    local) and serve it on the Web.

11
GIS allows for
  • Data capture
  • Data integration
  • Analysis
  • Projection
  • Data modeling
  • Display
  • Attribute table which forms a database

12
Possible effects of Climate change in the
Caribbean
  • Sea level rise
  • Increased saline intrusion of groundwater
  • Expansion of wetlands
  • Loss of beach
  • Damage to coastal infrastructure
  • Increased severity of floods
  • Increase in the number and severity of hurricanes
  • 2005 Hurricane Season

13
Application at ODPEM
  • JAHGIS
  • Create and Manage associated Database
  • Remote Sensing
  • NASA Whirlwind (Servir)
  • Hurrevac
  • UN Space Charter
  • Data Analysis
  • Vulnerability Assessment

14
Application at ODPEM
  • Collect damage assessment data
  • Storm surge run up
  • Flood area
  • Data Modelling
  • Preparation of Hazard Maps
  • Landslide and Flooding susceptibility

15
Application at ODPEM
  • Map preparation
  • Portmore Evacuation Map
  • Publishing of spatial data over the web
  • Collaboration with the Ministry of Agriculture

THE END
  • GIS SAVES LIVES
