| Visibility | The distance at which objects can be clearly seen. | Poor visibility due to fog, haze, or smog can make it difficult for the drone operator to see the drone and obstacles in its path. It can also impact the drone's ability to detect and avoid obstacles using sensors. |
Cloud cover and visibility are critical weather factors to consider when planning drone surveying operations. Cloudy conditions can affect the quality of images captured by the drone, as well as the accuracy of data collected. Low visibility due to fog or haze can make it challenging to navigate the drone safely and accurately.
Monitoring cloud cover and visibility is essential before and during drone surveying operations. It is recommended to fly drones in clear or partly cloudy conditions for optimal image quality and data accuracy. If visibility is limited due to fog or haze, it is best to postpone the surveying mission until conditions improve.
When flying in low visibility conditions, it is crucial to use additional safety measures such as GPS tracking or obstacle avoidance systems. These technologies can help maintain control over the drone and prevent accidents or collisions.
Precipitation, such as rain or snow, can have a significant impact on drone flight and data collection. Water can damage the drone's components, including the motors, electronics, and camera. Additionally, rain or snow can obstruct the camera lens, affecting the quality of images captured.
Monitoring precipitation is crucial to ensure safe and accurate drone surveying operations. It is recommended to avoid flying drones in rainy or snowy conditions to prevent damage to the drone and ensure data accuracy. If precipitation occurs during a surveying mission, it is best to land the drone immediately and protect it from moisture.
When flying in wet conditions, it is essential to take precautions to protect the drone. This can be done by using waterproof covers or cases, applying water-repellent coatings on the drone's components, and regularly inspecting the drone for any signs of water damage.
Thunderstorms and lightning pose a significant risk to drone surveying operations. Flying drones during thunderstorms can be extremely dangerous due to strong winds, heavy rain, and lightning strikes. Lightning strikes can cause severe damage to the drone and pose a safety risk to operators.
Monitoring weather forecasts for thunderstorms and lightning is crucial before planning any drone surveying missions. It is recommended to avoid flying drones during thunderstorms or when there is a high risk of lightning in the area. Postponing the mission until conditions improve is the safest course of action.
When thunderstorms or lightning occur unexpectedly during a surveying mission, it is essential to land the drone immediately and seek shelter. Operators should never attempt to fly or retrieve a drone during a thunderstorm or when lightning is present.
Atmospheric pressure can affect drone flight and data collection, especially in areas with high altitudes or extreme weather conditions. Changes in atmospheric pressure can impact the performance of the drone's motors and sensors, leading to unstable flight or inaccurate data.
Monitoring atmospheric pressure is crucial when flying drones in areas with high or low altitudes. It is recommended to calibrate the drone's sensors before each flight to ensure accurate data collection. Additionally, it is essential to monitor changes in atmospheric pressure during the flight and make necessary adjustments to maintain stability.
When flying in areas with high altitudes, it is important to consider the reduced air density and adjust the drone's flight parameters accordingly. This can include increasing the throttle or adjusting the pitch and roll angles to compensate for the thinner air.
Solar radiation and UV exposure can have an impact on drone battery life, especially in sunny conditions. High levels of solar radiation can cause the drone's batteries to heat up, reducing their overall capacity and flight time. Additionally, prolonged exposure to UV rays can degrade the drone's components over time.
Monitoring solar radiation and UV exposure is crucial when planning drone surveying missions. It is recommended to fly drones during early morning or late afternoon when solar radiation levels are lower. This can help prolong battery life and ensure optimal performance.
To protect the drone from excessive solar radiation and UV exposure, it is advisable to use sunshades or covers on the drone's components. Additionally, storing the drone in a cool and shaded area when not in use can help prevent heat buildup and extend battery life.
