The Role of GIS Mapping in Disaster Management 

No matter how cliché it sounds but the fact remains the fact: Geographic Information System or GIS mapping services have revolutionized the field of disaster management. The integration of spatial data with real-time information under the umbrella of GIS has been actively used to get crucial insights that aid in preparation, response, recovery, and mitigation phases of disaster management.

In this article, we are going to explore the role of GIS mapping in disaster management. So, stay with us!  

Understanding GIS and Its Components

GIS captures, store, manipulate, analyze, manage, and present spatial and geographic data. By combining multiple layers of information about a place, GIS helps stakeholders gain better understanding of the place. This information can include anything from the location of infrastructure to the prevalence of natural resources or the patterns of human behavior and natural resources as well. 

Now that you have acquired initial understanding of the GIS concept, let’s find out what its key components are:  

1. Hardware: Computers and servers that store and process spatial data. 
2. Software: Programs that facilitate data entry, analysis, and visualization (e.g., ArcGIS, QGIS). 
3. Data: Spatial and attribute data that provide detailed information about geographic features. 
4. People: Skilled professionals who analyse and interpret GIS data. 
5. Methods: Techniques and procedures used to analyse GIS data and generate actionable insights. 

GIS in Disaster Preparedness

GIS has emerged as a key tool to mitigate the impact of disasters. Here’s how GIS mapping services play key role in disaster mitigation phase:  

Risk Assessment

You can use GIS technology to identify those areas that are prone to natural disasters such as floods, earthquakes, and hurricanes. For this to happen, GIS analyses historical data vis-à-vis current conditions to make accurate predictions about disaster zones. This feature of GIS has greatly helped authorities concerned to implement preventive measures before the calamity strikes.

Resource Allocation

The second feature where GIS excels in disaster mitigation is that it enables authorities to optimize resources for better allocation. It does so by mapping the location of critical infrastructure, emergency services, and vulnerable populations. Using this feature efficiently, authorities have been able to place resources strategically in areas where they are needed most.  

Public Awareness

The third area where GIS have proven its mettle is public awareness vis-à-vis disaster management. Using valuable information extracted from GIS, authorities raise public awareness in the events of disaster about potential risks and safe zones. Similarly, authorities use interactive maps and mobile applications to educate masses about evacuation routes, emergency shelters, and safety protocols. 

GIS in Disaster Response 

Now that you have understood importance of GIS mapping services in disaster mitigation, let’s find out its role in disaster response.  

Real-Time Monitoring

GIS is an extremely powerful tool that integrates real-time data from a wide array of sources, including (but not limited to) satellites, weather stations, and social media. And by harnessing this amount of data, GIS provides real-time information about the progression of disaster. It enables authorities to monitor the situation in real-time and make informed decisions in favor of public safety.  

Situation Analysis

When it comes to responding to disaster, GIS proves its mettle again by visualizing the extent and impact of it. Emergency management teams use GIS data to assess the situations quickly. Similarly, emergency management teams use heat maps, flood models, and damage assessments to enable prioritization of areas that require immediate attention.  

Coordination and Communication

When dealing with disaster, streamline coordination and communication is the key. In absence of it, efforts will take a big hit. Shared GIS platforms act as single point of truth and ensure that everyone involved in disaster response efforts has access to real-time and the same information.  

Resource Management

By using GIS, authorities track the movement and deployment of resources to ensure that the same are used efficiently and are provided to the areas most in need. These resources include medical supplies, rescue teams, and food aid.   

GIS in Disaster Recovery 

GIS has proven to be extremely effectively when it comes to recovery efforts. GIS mapping services contributes to recovery by: 

Damage Assessment

By comparing pre and post-disaster imagery, authorities make accurate assessments about the losses. Using this valuable information, authorities have successfully identified the extent of destruction. Additionally, the same information is used to pan reconstruction efforts effectively.  

Rebuilding Infrastructure

When it comes to rebuilding infrastructure after a calamity hit an area, GIS is the second to none. It provides accurate data about the location and condition of infrastructure. Again, authorities can use analyse the historical data and compared it with the current one to build more resilient and sustainable infrastructure.  

Tracking Progress

GIS mapping services support the recovery process by monitoring and tracking the status of various projects and initiatives. Not only this feature helps greatly in ensuring accountability and transparency but also expedite the recovery phase.  

GIS enables the monitoring of recovery progress by tracking the status of various projects and initiatives. This helps in ensuring accountability and transparency in the recovery process.
