  5. nrsc Pre-Disaster Phase RISK IDENTIFICATION AND EVALUATION • The RISK evaluation is based on the vulnerability of elements at risk • Stock and state of constructions, infrastructure, facilities • Characteristics of population • Stock and state of societal and individual assets • Environment, topography, soil,.. • b. Construct vulnerability maps • c. Quantify the value of • elements at Risk • The RISK identificationis based upon the history of disasters that occurred in the past • Historical Data and Geo-environmental and terrain Conditions help to construct the hazard maps and to a. Quantify the hazard

  6. nrsc Pre-Disaster Phase DISASTER MITIGATION, PREDICTIONS, WARNING AND PREPAREDNESS • Predictions and Warningsalert for preparedness and efficient response • Disaster Preparedness aims to reduce the loss from future disasters • Consists of planned measures to deal with a disaster • Involve mock drills • Disaster Mitigation • Reduce the Hazard or vulnerability or both • Continuous and long term efforts through: • ENGINEERING MEASURES • PHYSICAL PLANNING MEASURES • ECONOMIC MEASURES • MANAGEMENT & INSTITUTIONAL MEASURES • SOCIAL MEASURES

  7. nrsc During the Disaster RESPONSE Post - Disaster RECONSTRUCTION • IMPLEMENTATION OF PLANNING OR MEASURES PUT IN PLACE IN THE PREPAREDNESS PHASE • SAVING LIFE – PRIORITY • Evacuation • Assessment and Emergency Relief • Logistics and Supply • Communication and information Management • RESTORING NORMALCY • RESCUE-RELIEF-REHABILITATION

  9. nrsc Database systems in which the data are spatially indexed, upon which a set of procedures are operated in order to answer queries about spatial entities in the database Information systems for capturing, storing, retrieving, analyzing and displaying spatial data DEFINITIONS USEA Powerful tool for solving real-world problems by spatial analysis People Software Method Thematic data layers COMPONENTS Hardware Data

  10. Provided…. The data is stored with: 2. Attribute Information: What is it? 1. Location Information: Where is it? Species: Oak Height: 15m Age: 75 Yrs 51°N, 112°W

  11. Features Raster Tessellation Sampling RASTER DATA REPRESENTATION Regular square tessellation is RASTER data model

  12. VECTORDATAREPRESENTATION • object based approach • representation by coordinate system • built on two common concepts • decomposition of spatial objects into • basic graphic elements • spatial relation between these • elements (topology) • basic graphic elements • point, line, polygon

  13. NETWORK ANALYSIS – AM/FM, Route/Resource Management • SURFACE ANALYSIS – Runoff Modeling /Topographic Analysis • POINT PATTERN ANALYSIS – Spatial extrapolation • SITE SUITSBILITY ANALYSIS - Nuclear waste disposal site identification • HAZARD / RISK MODELLING - Slope stability analysis, Flood Forecasting, Drought Modelling…. COMMON MODELLING APPLICATIONS
