Operation Steps Of UAV Aerial Mapping
UAV Aerial Mapping is convenient, accurate and efficient, so it becomes more and more popular. More and more engineering projects are willing to use drones to collect survey data.
There are many things to keep in mind when using drones for mapping. WELKINUAV summarizes the following 12 steps for UAV pilots and hopes to help you use the drone to complete the surveying missions easily.

- Three Essentials About Aerial Mapping
1. Judge weather conditions
UAV aerial survey, the weather conditions affects a lot. Before starting the aerial photography, it is necessary to get the weather conditions of the day and observe the thickness of the clouds, the light and the visibility of the air.
2. Arrive at the take-off place
When it knows that the weather is suitable for aerial mapping, bring the survey drone, radio, ground control station, and other related equipment to the aerial take-off place.
The take-off place is usually checked in advance, requiring the site to be flat. No wires, tall buildings, etc. Plan the flight sequence in advance is necessary.
3. Measure wind speed
when arriving at the scene, it needs to measure the wind speed.
4. Set up a radio station
The radio is used for communication between the ground control station and the survey drone.
5. Working log
Record the wind speed, weather, takeoff and landing information, and other data, in order to analyze and summarize.
6. Adjust the attitude angle
If the take-off location is 200km far away from the last take-off location, it needs to adjust the attitude and angle of the survey done to ensure accurate communication.
7. Manual remote control test
Adjust the flight mode to the manual remote flight state and test whether the nose, body, and tail can be operated as directed.
The manual remote control mode is mainly used for emergency treatment when the survey drone takes off and land in case of special circumstances.
8. Preparation before takeoff
Before taking off, check whether the aerial camera and the flight control system are connected. The aerial survey drone needs to be parallel to the wind direction, and no people and vehicles move around the take-off place.
9. Aerial survey drone takes off
When it’s are ready, you can control the aerial survey drone to take off. The aerial survey drone pilot should hold the remote control and stand by, and manually adjust the attitude and flight height of the mapping drone.
10. Monitor the flight
It needs to monitor three parts:
a. Monitor the altitude, speed and flight route of the mapping drone;
b. Monitor engine speed, airspeed and ground speed of the mapping drone;
c. Check the number of aerial photos.
11. The landing of mapping drone
After the land survey drone has completed the aerial flight according to the set route. It needs to land at the designated location.
Return with one click. If there happens a sudden situation, it needs to change the landing place as soon as possible.
12. Export and check data
When the aerial survey UAV lands, it needs to check the aerial photos and the aerial survey UAV. Combined with the line rate and attitude angle to determine whether to continue flying or not. Theoretically, the flight control range of one take-off location is 300km.
