- 2. Disaster Management Topic :- GEO-INFORMATION IN DISASTER MANAGEMENT (RS,GIS,GPS and RS)
- 3. GEO- INFORMATION A Geographic Information System (GIS) is a computer-based system including software, hardware, people, and geographic information A method to visualize, manipulate, analyze, and display spatial data to study the world
- 5. GIS OBJECTIVES MAXIMIZE THE EFFICENCY OF PLANNING AND DECISION MAKING. PROVIDE EFFICENT MEANS FOR DATA DISTRIBUTION AND HANDLING. ELIMINATION OF REDUNDANT DATABASE-MINIMIZE DUPLICATION. CAPACITY TO INTEGRATE INFORMATION FROM MANY SOURCES. COMPLEX ANALYSIS/ QUERY INVOLVING GEOGRAPHICAL REFERENCED DATA TO INTEGRATE
- 6. How GIS use in disaster management 1) EARTQUAKE GIS can be useful for monitoring historical sites of earthquake also to Response & data management for recovery. It’s also useful for Impact assessment.
- 7. 2) FLOOD •Flood mapping from Macro level to Micro level. •Flood Zone mapping. •Detecting Potential Site of Flood in reference with rainfall •Elevation Mapping •Preparing Response map in response to manage after flood situation
- 8. Situational Awareness Disaster and emergency management in situational awareness is essential thing. GIS techniques plays vital role to provide locational information of the event, that is, where is the event happened and what happening exactly in real time. Also by linking people, processes spatial information situational awareness established. GIS map interface important in handling emergency condition.
- 9. REMOTE SENSING Quickly assessing severity and impact of damage due to flooding, earthquakes, oil spills and other disasters Rapidly identifying hardest-hit disaster areas in order to provide early warning of potential disasters Developing, maintaining or updating accurate base maps
- 11. •the science of acquiring information about the Earth using remote instruments, such as satellites is inherently useful for disaster management. •Satellites offer accurate, frequent and almost instantaneous data over large areas anywhere in the world. • When a disaster strikes, remote sensing is often the only way to view what is happening on the ground
- 12. REMOTE SENSING FLOODING Using remote technology however, would allow response workers to stay away from danger zones while at the same time gather pertinent information to facilitate timely response, rescue and relief efforts. It is always going to be difficult, if not impossible, for planners to identify all the areas likely to experience flooding in any location
- 14. Remote sensing and Earthquakes This technology will help in identifying the structural and non-structural earthquake hazards that are present and employ the most appropriate tool for minimizing these risks. Using remote sensing technology, however, would significantly improve the timeliness and quality of aid that can be provided. it would be advantageous to employ the service of remote sensing for deep
- 17. GPS (global positioning system) The Global Positioning System (GPS) is a satellite-based navigation system made up of a network of 24 satellites placed into orbit by the U.S. department of Defense. GPS was originally intended for military applications, but in the 1980s, the government made the system available for civilian use. GPS works in any weather conditions, anywhere in the world, 24 hours a day.
- 19. How GPS Works: Overview Receivers use an almanac that includes The position of all satellites every second This is updated monthly from control stations The satellite signal is received, compared with the receiver’s internal clock, and used to calculate the distance from that satellite Trilateration (similar to triangulation) is used to determine location from multiple satellite signals
