Geospatial Technologies: The Cornerstone of Effective Disaster Management

On the backdrop of escalating natural disaster threats, the Association for Geographic Information (AGI) GeoResilience Symposium underscored the pivotal role of geospatial technologies in disaster management. The symposium's attendees, including eminent personalities like Dr. Mrutunjay Mohapatra, Director General of Meteorology at India Meteorological Department (IMD), and Ms. Srilakshmi P, Head of National Remote Sensing Centre - Indian Space Research Organization (NRSC-ISRO), highlighted that high-resolution geospatial data is the key to understanding terrain, infrastructure, and population in disaster-prone areas.

Geospatial Technologies: Aiding Disaster Preparedness, Response, and Recovery

Experts at the symposium stressed the need for better data to support efforts in disaster preparedness, response, and recovery. For instance, the Digital Elevation Modelling (DEM) was discussed as a paramount technique for identifying risk areas for natural hazards and assessing disaster damage. Monitoring land subsidence, as illustrated by the Joshimath tragedy in Uttarakhand, India, was also identified as a critical area where geospatial technology can make a significant impact.

Subsurface Characterizations: Key to Mitigating Disasters

Dr. Anand Kumar Pandey emphasized the need for subsurface characterizations to comprehend and mitigate such catastrophic events. A thorough understanding of the subsurface can help in predicting potential disasters, enabling authorities to take effective preventive measures.

NDEM: An Essential Repository for Disaster Management Data

Ms. Srilakshmi P of NRSC-ISRO introduced the National Database for Emergency Management (NDEM), a critical repository for disaster management data. The NDEM serves as a comprehensive platform for all necessary information, aiding in effective and prompt disaster management.

Furthermore, the symposium highlighted the importance of hazard atlases and Early Warning Systems using geospatial technologies as key tools for preparedness and mitigation. These tools help in not just predicting disasters but also in devising effective strategies to minimize their impact.

Concluding the symposium, the need for investment in geospatial data and technologies was emphasized. As climate change continues to pose increased threats of natural disasters, enhancing disaster resilience through state-of-the-art geospatial technologies is no longer an option but a necessity for a more prepared and resilient society.
