Specific Risk (Rs) = H x V x E(value of)
Total Risk (Rt) = H x ∑ (V x E (value of)
… impact beyond the manageable

Pre-Disaster PhasePre-Disaster PhaseRISK 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 hazarda. 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 mapsb. Construct vulnerability maps
c. Quantify the c. Quantify the valuevalue of of elements at Riskelements at Risk
Pre-Disaster PhasePre-Disaster PhaseDISASTER 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 WarningsPredictions 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
During the DisasterDuring the DisasterRESPONSE

Information systems for capturing, storing, retrieving, analyzing and
displaying spatial data
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

1. Location Information: Where is it?
51°N, 112°W
2. Attribute Information:
What is it?

RASTER DATA REPRESENTATION
Tessellation
RasterFeatures
Sampling
Regular square tessellation is RASTER data model
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
