Geo-informatics in Disaster Management

Geo-informatics is the science of gathering, analyzing, and using geographic data. It is the "Eye in the Sky" for disaster managers.

1. Remote Sensing (RS):

• Definition: Gathering information about the earth without physical contact, typically using Satellites or Drones.
• Application:
• Tracking cyclone paths (Meteorological satellites).
• Mapping flood extent (Optical/Radar satellites).
• Assessing drought impact on crops.

2. Geographic Information System (GIS):

• Definition: A computer system for capturing, storing, checking, and displaying data related to positions on Earth's surface. It's essentially "Smart Mapping".
• Application:
• Overlaying different layers (e.g., Road map + Flood map) to see which roads are blocked.
• Identifying hospitals near a blast site.
• Planning evacuation routes.

3. Global Positioning System (GPS):

• Definition: A satellite-based navigation system that provides precise location and time information.
• Application:
• Guiding Search and Rescue (SAR) teams to the exact location of victims.
• Tracking vehicle movements during relief operations.

Summary of Tools:

• RS: "The Camera" (Takes pictures).
• GPS: "The Compass" (Tells location).
• GIS: "The Brain" (Analyzes the data).
