Disaster Exposure Mapping
Disaster Exposure Mapping
How it Works
GeoEDGE partnered with the World Bank and Sri Lanka’s Disaster Management Centre (DMC) to support national resilience efforts through geospatial data enhancement. This project involved developing detailed exposure datasets for high-risk districts, contributing directly to Sri Lanka’s national geospatial platform.
The datasets provided critical baseline data on buildings, infrastructure, and population distribution, enabling disaster managers to visualize risk scenarios, assess vulnerability, and plan more effectively for disaster response and recovery.
“By strengthening national exposure datasets, this project builds the foundation for smarter, faster disaster response and risk-informed planning.”
Process & Results
The project began by identifying vulnerable districts and conducting pilot mapping exercises to capture high-resolution exposure data. GeoEDGE used remote sensing, field validation, and GIS-based modeling to develop building-level datasets aligned with national standards.
These datasets supported post-disaster payout assessments under the National Natural Disaster Insurance Scheme (NNDIS), managed by the National Insurance Trust Fund (NITF). The outcome enabled the National Disaster Relief Services Centre (NDRSC) to adopt more efficient building damage assessment mechanisms, reducing delays in compensation and improving planning for future disaster risk reduction. This effort also contributed to a more integrated, risk-informed approach across government agencies.
