Applications of remote sensing and gis

Remote sensing uses instruments like satellites to acquire information about the Earth that can help with disaster management. Geographic information systems (GIS) are computer tools that analyze geographic features and spatially referenced data. Together, remote sensing and GIS can map vulnerable areas, track disasters over time, and help with emergency response by identifying shelter locations and distributing relief effectively. A case study on a 2013 cyclone in India demonstrated how remote sensing data from multiple dates was analyzed in a GIS to monitor the storm and support disaster risk reduction activities.

REMOTE SENSING

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

4

APPLICATION OF REMOTE SENSING ◦ Agriculture - airborne images (Aerial Photography) ◦ Geology – Conventional Radar ◦ Ultrasound (acoustic) ◦ Radiometers and Photometers – Tsunami ◦ Forest fires ◦ Tracking Clouds ◦ Drought , Volcano , Landslide , Floods ◦ Terrorism and War

5

GIS Geographic Information System

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 .

◦ 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
