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 system that
can analyze, query and display data using
digitized maps and tables for planning and
decision-making (Anonymous)
Remote Sensing
Remote sensing is the short or largescale 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
