Geoinformatics, which integrates geographic information systems (GIS), remote sensing, global positioning systems (GPS), and spatial data analysis, has become a pivotal tool in disaster risk reduction (DRR). It provides comprehensive spatial and temporal insights into natural and human-induced hazards, vulnerabilities, and exposure patterns, enabling decision-makers to plan, respond, and mitigate disaster risks more effectively. The application of geoinformatics in DRR spans several stages, including hazard assessment, vulnerability analysis, early warning systems, disaster response, and recovery planning. One of the primary applications of geoinformatics in disaster risk reduction is hazard mapping. Remote sensing satellites and aerial imagery allow scientists and disaster managers to identify and monitor natural hazards such as floods, earthquakes, landslides, cyclones, and droughts. High-resolution satellite imagery helps detect changes in land use, vegetation cover, water bodies, and coastal areas that could influence the frequency and intensity of disasters. For instance, satellite data can reveal areas prone to landslides by analyzing slope, soil type, rainfall patterns, and vegetation cover. Similarly, flood-prone zones can be identified using digital elevation models (DEMs), historical flood data, and rainfall patterns, providing vital information for planning flood mitigation measures. Geoinformatics also plays a critical role in vulnerability assessment. Vulnerability refers to the susceptibility of populations, infrastructure, and ecosystems to the impacts of hazards.
