Pre-Disaster Phase RISK IDENTIFICATION AND EVALUATION The RISK identification is 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 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 elements at Risk

Pre-Disaster Phase DISASTER MITIGATION, PREDICTIONS, WARNING AND PREPAREDNESS 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 Predictions and Warnings Predictions and Warnings alert for preparedness and efficient response Disaster Preparedness Disaster Preparedness aims to reduce the loss from future disasters Consists of planned measures to deal with a disaster Involve mock drills

RASTER DATA REPRESENTATION Tessellation Raster Features Sampling Regular square tessellation is RASTER data model
16
VECTOR DATA REPRESENTATION -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
