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).

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
