Now let the Chinese MMCUAV surveying and mapping experts tell you the detailed operation steps of mapping and mapping drones in determining rural land rights.

1. How mapping drones make low-altitude aerial surveys
How does the mapping drone perform low-altitude aerial photography? What are
the detailed steps? What are the precautions in aerial surveys? Now let the Chinese
MMCUAV surveying and mapping experts tell you the detailed operation steps of
mapping and mapping drones in determining rural land rights.
1. Judge weather conditions
The quality of the weather directly affects the effect of aerial photography, so we
must grasp the weather conditions of the day before observing the aerial
photography, and observe the cloud thickness, light and air visibility.
2.Measure the wind speed on site
After arriving at the aerial survey site, first determine the wind speed. See if the
mapping drone can resist the wind speed at that time, and whether it can adapt to
the temperature at that time.
3.Ejection rack
The catapult is generally set upwind to ensure that the plane takes off smoothly.
Huatest P700E adopts the configuration of an integrated ejection rack, which has
less requirements on the site and strong adaptability to the terrain. Compared with
other products, the design of the ejection rope is more in line with the concept of

2. convenience and speed, and at the same time, it guarantees the operator's safety to
the greatest extent.
4. Set up the radio
The radio is used for communication between the ground station and the drone. At
this stage, most surveying and mapping drones use radios to exchange data
between the drones and the ground station. The high-frequency radio stations of
Huasue P700E can perform ultra-long-range monitoring up to 50 kilometers to
ensure the safe and efficient operation of the aircraft.
5. Record the day's job log
Record the current day's wind speed, weather, takeoff and landing coordinates, etc.,
and keep it for future reference and analysis.
6, attitude angle adjustment
For take-off points that are more than 200km from the last take-off point, the
attitude and angle of the aircraft need to be adjusted to ensure that the aircraft
communicates accurately. The drone's body is equipped with electronic compass,
magnetic calibration and other equipment to ensure the aircraft's self-attitude
control during flight. Due to the different geomagnetic conditions in various places,
Huatest P700E comes with a calibration system to respond to different
geomagnetic conditions in various places. Human-machine interference and

3. potential safety hazards.
7, put the drone on the catapult
During installation, it is necessary to check whether the parts of the drone are
tightly connected, the power supply wiring of the ejection rack is correctly
connected, and the power is sufficient.
8.Manual remote test
Set the flight mode to the manual remote control flight state, and test whether the
nose, fuselage, and tail can operate as instructed. The manual remote control mode
is mainly used for emergency handling when drones take off and land in special
situations.
9. Preparation before take-off
Before taking off, check whether the aerial camera is connected to the flight control
system, the parachute bag is on standby, parallel to the wind direction, and no one
is moving.
10.Drone take off
After all the preparations are completed, you can take off. At this time, the operator
should hold the manual operation lever on standby, observe the situation on site,
and manually adjust the aircraft attitude and flight height at any time as needed.

4. 11. Flight monitoring
This process does three things:
① Monitoring of altitude, speed and flight trajectory;
②Monitor engine speed, airspeed and ground speed;
③ Check the number of photos taken at any time.
12.Drone landing
After the drone has finished flying according to the set route, it will land at the
designated location. The manual remote control operator stands by at the
designated place, and adjusts the landing place in time when there is a sudden
strong wind at the landing site, and people move around.
13.Data export check
After landing, check and evaluate the photo data and the aircraft as a whole,
determine whether to go around in combination with the line-up rate and attitude
angle, and continue to complete aerial missions or transitions in the vicinity. In
theory, the flight control range of a landing point is 300 square kilometers. .
Nationwide, UAV remote sensing technology has been used for rural land rights
determination for many times. The technology has matured, not only the accuracy
of the results is far better than traditional measurement methods, but also the work

5. time is greatly shortened, reducing the workload of rural grassroots management ,
Saving manpower and material resources, it is worth promoting in the work of
determining land rights in rural areas. Surveying and mapping drones are serving
all aspects of economic and social development with their high mobility, high cost
performance, and high security.
