HIGHLIGHTING THE USE OF GIS IN
CLIMATE CHANGE
UWI CLIMATE CHANGEJUNE, 2007
Overview of presentation
• What is GIS• Associated tools
– Remote Sensing– Global Positioning System
• Web publishing of maps/data• Application at ODPEM
What is GIS?Geographic Information Systems (GIS) is a spatial database management systemspatial database management system that can analyze, query and display analyze, query and display datadata using digitized maps and tablesdigitized maps and tables for planning and decision-making planning and decision-making (Anonymous)
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).
Remote Sensing allows for:
• Image interpretation & classification• Time-series image analysis• Drought analysis• Tracking of hurricanes
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.
GPS devices allows you to:
• Gather accurate spatial data– Flood extent– Sea level rise– Storm surge runup– Heights above sea level
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.
GIS allows for:
• Data capture• Data integration• Analysis• Projection • Data modeling• Display• Attribute table which forms a
database
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
Application at ODPEM
• JAHGIS– Create and Manage associated Database
• Remote Sensing– NASA Whirlwind (Servir)– Hurrevac– UN Space Charter
• Data Analysis– Vulnerability Assessment
Application at ODPEM
• Collect damage assessment data•Storm surge run up•Flood area
• Data Modelling •Preparation of Hazard Maps•Landslide and Flooding susceptibility
Application at ODPEM
• Map preparation– Portmore Evacuation Map
• Publishing of spatial data over the web– Collaboration with the Ministry of
Agriculture
