Geo-Spatial Data Modeling to Estimate Flood Affected Population in a Near Real-Time Scenario: Pakistan Floods 2011

Problem Description / Relevance to Water Security: 

During humanitarian emergencies, Well-timed information on losses, affected areas and affected population is essential to plan any effective response and optimum resource allocation that are in hand. However, this is, conventionally, only available following an on-ground assessment.

ICT Application / Outcome: 

A spatial model was developed for the assessment of the flood-affected population in a near real-time scenario using spatial analysis. A flood extent vector, extracted from MODIS daily images, was superimposed on a LandScan population grid to estimate the population count living in the flooded area, aggregated by their respective administrative level.
