5 Reasons Drone Surveys Are The Future Of Land Survey And Mapping
Drones are effective tools used by Aerial survey companies for mapping and surveying properties. They fly over the ground to carry out tasks like 3D mapping, land surveys, photogrammetry, and topographic surveying. Presented below is all the information you need to know about drone surveying.
How Does a Drone Survey Work?
A drone survey makes use of multispectral and RGB (Reed Green Blue) cameras with downward-facing sensors to take pictures of the subject while it flies above the ground. Nowadays, many drones have LiDAR payloads to aid in data collection. The RGB camera takes pictures of the ground (aka subject) from various perspectives as it surveys the area. The precise coordinates are tagged with each angle.
Why Drone Surveys Are Considered the Most Efficient?
1. Accuracy
UAV (Unmanned Aerial Vehicle) and camera technology owned by aerial survey companies have undergone expeditious technological advancements in the past several years. Present-day drones can capture images and videos up to 5.2K in resolution. The higher pixel density makes sure that the aerial survey is performed at maximum efficiency. What’s more, the new cutting-edge stabilization techniques imbued in drones allow them to take ultra-high-definition pictures even when faced with extreme and inclement weather.
One of the major reasons why drones have applaudable efficiency is because of their accuracy, high-tech GPS systems, and real-time kinematics or RTK, which is integrated into some drones' software. Combining accuracy with other inherent advantages, only a fool would pass on drones when conducting aerial surveys.
2. Speed
Drones being so incredibly flexible, can actually cover huge expanses of land in a relatively short amount of time. Another reason they have such super speed is that the flights are pre-programmed. This is very effective in reducing the total time taken in the project (from initial planning to data processing to delivery of the end product). Drone surveys are your best shot for time-sensitive projects.
3. Safety
Does your project involve working in a compromised, risky, or sensitive area? Drones could be exactly what you are looking for. They are the perfect data collection tool since they pose no risk to the surveying pilot flying the drone or to the general public. All data is easily collected while the drone is airborne. The risk is practically nil when it comes to one's health or safety. This also means that the project can now be completed way more quickly as there is no longer a need for comprehensive health and safety considerations.
4. Accessibility
This doesn’t need telling twice, but UAVs boost the accessibility factor by many points. With a UAV at your service, it is easier than ever before to access hard-to-reach places. Be it roofs, masts, towers, impossibly tall skyscrapers, or even wound turbines; it is a piece of cake for the drone to reach there. Most modern drones are equipped with 30X zoom optical equipment, ensuring that even with remote access, the data is of excellent quality.
5. Cost Efficient
Drone surveys have opened the doors to newer avenues in terms of what is feasible and affordable for aerial survey companies. All thanks to drones’ low overhead and incredible cost efficiency when compared to terrestrial, light aircraft, and helicopter surveys. The perspectives that were previously out of reach due to bulk expenses and operational issues are now easily attainable.
