3. Remote – far away
Sensing – Observing or Acquiring Some Information
Remote Sensing is the science of acquiring information about the earth
using remote instruments such as satellites which is useful for disaster
management
6. Geographic Information System(GIS)
◦ GEO – Earth
◦ Geography – study of Earth
◦ Information - Capturing , Managing , Analyzing and understanding
Information
◦ System – A set of Software , Hardware and Data , Processing…….
7. A Geographic Information System, can be defined as an organized collection
of software and Geographic data that allows efficient storage , analysis and
presentation of spatially explicit and geographically referenced information
from Global Positioning System
GPS - GLOBAL POSITIONING SYSTEM
GIS Components – 1. Graphical Data (Lands , Rivers , etc.,)
2. Tabular Data (Population , Air Pollution , etc., )
8. APPLICATION OF GIS
◦ EMERGENCY SHELTERS – GIS can be used by shelter operators to capture specific personal details of persons being
housed at the shelters . It would make it possible to assess the number of needed shelters and the structure of that suffering population
◦ DISTRIBUTION OF RELIEF – In affected areas during and after disaster , Food drops is always likely to take place. This process can
be helped with GIS as maps can be generated which identify the specific area with clusters of victims are located and the unique need of
persons within these clusters.
◦ DATA GATHERING – The data is gathered for the analysis and to assess the need of activities and actions before during and after the
disaster. By the use of this data , maps of most vulnerable area can be produced and thoe areas can be highlighted .
9. ◦ Identification of cyclone shelters location
◦ Use in Automated weather Stations
◦ Preparation of the district Vulnerability Maps
◦ Strengthening of embankment
◦ Repair of roads
◦ Identification of Weak points in the embankments
◦ Preparing the base map indicating location
