Drone Solutions For Disaster Management: Aerial Surveys And Search Operations
Natural disasters like earthquakes, hurricanes, and floods can strike without warning, leading to devastating consequences for the people living in the affected areas. It becomes critical to find and locate survivors, reach them with aid, assess the damage, and create an action plan for recovery. However, conventional methods of disaster management can be time-consuming, costly and may not be practical in all situations. Fortunately, the emergence of drone technology has substantially improved disaster response and recovery efforts. Drones can provide faster response times, efficient surveys, and live aerial footage of the situation. In this article, we will explore how drones can be used for disaster management, particularly for aerial surveys and search operations.

How Drones Are Being Used for Disaster Management?

 How Drones Are Being Used For Disaster Management?
Drones are increasingly becoming an essential tool for disaster management and mitigation because of several reasons. Firstly, drones can easily and quickly access areasaffected by disasters where it might be difficult or impossible for humans to reach. Secondly, drones canfly at low altitudes or hover in place, capturing detailed aerial images of the disaster-affected areas. Lastly, drones have become more affordable and widely available, making them a practical solution.Drones can be employed in several ways to aid rescue and recovery efforts during disasters:

1. Search and Rescue

One of the most significant advantages of drones for disaster management is that they can assist search and rescue teams with live footage of affected areas. During a disaster, rescue officials get a bird’s eye view of the situation and can plan fast on how to save people trapped in the affected areas. The live-streaming drone footage helps alert the victims while rescuing teams are on the way, leading to a faster and more effective rescue system. Mathias Griebel, the chief operating officer for DJI, the largest drone manufacturer in the world, says, “In the first few hours after a disaster, having qualified responders out searching, either by foot or by drone, saves lives and provides vital intelligence.”

2. Disaster Risk Assessment

Drones can collect and provide high-resolution images that allow officials to assess the disaster area and evaluate the extent of damage. Disaster management authorities can use drones to map the terrain and evaluate individual buildings or neighborhoods’ structural safety. The data collected from drones can update governments, NGOs, and other emergency support systems to outline existing scenarios of disaster-stricken areas. Furthermore, drones can also help gather information about people who might need urgent assistance like elderly people or infants.

3. Real-time Communication with Disaster-affected people

Communication during natural disasters can be a real challenge. Power outages and infrastructure damage can significantly hinder rescue efforts. Drones can be equipped with cell repeaters or other communication equipment that can boost the signal and enable disaster victims to establish contact with the outside world, including support services, such as the police and emergency services department.

The Role of Aerial Surveys in Disaster Management

The Role Of Aerial Surveys In Disaster Management
Aerial surveys refer to the use of drones to record images or videos of an area or environment from the air. These surveys can provide vital information for disaster management that can improve the overall rescue and recovery effort.

1. Efficient and Comprehensive Surveys

Drones can capture extensive and detailed aerial imagery of disaster-affected areas. This imagery helps disaster response teams decide on the various obstacles and risks to the affected areas. It helps identify landslides, hazardous material spills, broken gas and oil pipelines, road and building damage, and other hazards that may not be visible from the ground. Surveying the damage using drones’ advanced vision sensors eliminates the hazards that could block or interfere with on-the-ground rescue work, enabling faster recovery.

2. Cost-effective Disaster monitoring

Manual inspection for disaster monitoring can sometimes be expensive due toextensive damages in the affected areas since several factors need to be accounted for before using physical contact. However, with drones, the same level of detail and data can be captured for a lesser cost and within a short time. Furthermore, drones can be used to collect real-time data on disasters, improving prediction models and enabling emergency officials to be better prepared for future catastrophes.

3. Effective Damage Assessment

Drones can capture detailed imagery to assess and monitor the damage to structures and critical infrastructure. Detailed imagery is then analyzed with data-rich algorithms for accurate and comprehensive damage assessment in a quick and efficient manner.

Does Drone Technology Have Limitations in Disaster Management?

Does Drone Technology Have Limitations In Disaster Management?
While drones have proved to be an efficient solution in disaster management, they have some limitations that must be addressed.

1. Communication issues

Although drones have the potential to assist in disaster communication, they may not be useful in some disaster scenarios. Communication signals may be blocked or lost in remote areas, which may limit drone functionality. Moreover, weak mobile networks can interfere with the drone’s remote control system.

2. Weather conditions

A drone’s operability can be hindered by harsh weather conditions. High winds and heavy rain can make rescue operations difficult, increasing the drone’s cost of operation. During foggy days, visibility for the drone operator can be hindered, potentially causing the drone to lose communication and control, risking disaster response team members in the area.

3. Legal and ethical concerns:

The use of drones during disaster management requires extensive research into regulations. While drones have the potential to aid in relief efforts, drone users must be aware of flight regulations and airspace the presence of airborne rescue efforts engaging in the area to prevent potential conflict.

Conclusion

Conclusion
Drones are becoming increasingly valuable when it comes to disaster management, particularly for aerial photographic surveys and search operations. Aerial surveys carried out by drones provide vital information about the level of damage caused by natural disasters, enabling governments and aid agencies to effectively deploy resources and implement intervention measures. The emergency services can use data collected from drone footage and thus help save lives and aid in the relief process. While drones have their limitations and concerns during disaster management, they have proven to be an effective and cost-efficient tool in disaster response, hence highlighting evidence of their instrumental role during any disaster.See you again in another interesting article.
