How Are Drones Being Used For Remote Sensing

Unmanned Aerial Vehicles (UAVs), commonly known as drones are independent aircraft operated remotely with human interference or autonomously by a computer fitted in them. These sophisticated flying machines have now been heavily incorporated into various industries that rely on real-time data and assessment of various factors, including land and its remote sensing.

These copters vary in sizes and carry loads of up to 5 kg depending on their size. They are equipped with sensors like thermal, optical, LIDAR, multispectral, and hyperspectral to help capture dynamic data with accuracy. With researches and studies going on consistently, drones have started to be used in various sectors and have proven very helpful to assess landforms aerially without the expense of a full aircraft or jet being needed.

In the field of remote sensing, there has been a sharp rise in the use of UAVs due to convenience, flexibility, and considerable cost reduction. Here are a few uses of UAVs and drones in remote sensing:
 

3-D Terrain Modelling and Construction


The AEC industry heavily relies on remote sensing. From terrain assessment to final implementation of projects-this industry uses remote sensing throughout a project’s lifespan. UAVs are being used in this assessment and research extensively as they provide accurate information and even help in producing data for volumetric analysis. The realistic, digital, and balanced 3-D models presented digitally or physically utilise UAVs for sensing and mapping the terrains, environmental impact, and other essential metrics.
 

Large Scale Mapping in Urban Development


Mapping in the Urban Development sector has taken to UAVs due to their flexibility and viability to map large urban areas without losing essential information. UAVs reduce the time of mapping considerably with the help of high quality and resolution imagery captured aerially to give accurate and dependable data for decision making and further planning and development.
 

Agriculture and Crop Management

Agriculture and collateral industries use UAVs to assess crops, study soil and land data, and analyse growth patterns. Most critically, UAVs are used to assess infestation and crop damage in case of a breakout. This data can help formulate a plan to eradicate the infestation or work towards improvement. The results help in timely decision making as an infestation can lead to high quantity crop damage.

Drones are also used to study soil and terrain that helps in decision making for the future and helps in crop management as well.
 

Mapping of disaster-affected areas

Drones are extensively used in disaster management and control. They not only help in the assessment of areas to find disaster-prone landforms, but they also help in mapping of disaster-affected areas and the extent of damage without having to risk more lives.

UAVs help find areas that might be prone to disasters due to their environment, the impact of disasters in other areas, and due to their proximity to nature’s elements like oceans, forests, etc.

Mapping of disaster-affected areas is important to find out the loss of life and property, the impact of the disaster in its neighbouring regions, and to create contingency and evacuation plans. All of this heavily relies on remote sensing done by UAVs.

These are only some of the industries that use UAVs for remote sensing. Commercial usage of drones for remote sensing growing and is bound to take the industry by a storm. We can only see this industry growing far and wide, and at unprecedented speed.
