Digital cartography and natural disaster management

  1. 1. Presented By: Medam Mariyam kareem Presented By: MuhammadAzaz Roll no 1811 Department of Geography GC University Faisalabad
  2. 2.  Disaster Management  A systematic process which aims to reduce the impact or consequences of any adverse event like, Flood, Earthquake, Disease etc. It is more then just response and relief.  Hazard  It is a potential for a natural or Human-Caused event with negative impacts or consequences.  Emergency  It is a situation generated by real or imminent occurrence od an event that requires immediate response/Attention.  Disaster  It is a natural or human-caused event which causes intensive negative impact on people, goods, services and/or environment acceding the affected community’s capability to respond.
  3. 3.  An Emergency is a situation in which the community is capable of coping.  A Disaster is a situation in which the community is incapable of coping. It is a natural or human-caused event which causes intense negative impacts on people, goods, services and/or the environment,
  4. 4.  Better data storage  Better data analysis  Handy in planning  Helpful for stakeholders/ Decision Makers
  5. 5.  In digital cartography GIS is a tool that allows users to create interactive queries (user created searches), analyze the spatial information, edit data, maps, and present the results of all these operations.  The specific application in Risk Assessment are, Hazard mapping to show earthquake, floods, landslide or fire.  These maps are used for warning system.
  6. 6.  In digital cartography GIS application can be useful in the following activities  To create Hazard inventory maps  Locate Critical Facilities  To help out the peoples
  7. 7.  Planning Digital cartography is useful in helping with forward planning. It provides the framework for planners and disaster managers to view spatial data by way of computer based maps.  Mitigation  Representation of High risk areas  Facilitates the implementation of necessary mechanism to lessen the impact.  Preparedness  Identification of emergency areas on the map.  Positions of related departments, Agencies, and Human Resources,  Make it easier for security and shelters provides to plan the strategies  Answer that who is to be based where and at what phase of emergency
  8. 8.  Response  Provide accurate information on exact location of an emergency situation  Time saving during the determination of trouble areas (Quick Response)  Used as floor guide for evacuation routes  Recovery  Mapping level of damage  Information related to disrupted infrastructure, number of persons died or injured and impact on Environment.
  9. 9.  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 like, children, adults, disables etc..
  10. 10.  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 areas with clusters of victims are located and the unique need of persons within these clusters.
  11. 11.  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 areas can be produced and those areas can be highlighted which are most prone to disasters.
  12. 12.  Ability to represent geographical information 2D and 3D  It provides the facility to integrate the different geo-spatial information.  It effectively collect, analyze, manage and distribute up-to-date information  It is versatile and easy to use for big purposes, but requires a little training to get individuals involved in process.  The GIS based database provides better environment for future planning.
