What is drone mapping and surveying?

A drone survey is the use of drones or unmanned aerial vehicles (UAVs) equipped with RGB cameras, multispectral cameras, or LiDAR payloads to collect data. And then this data is transmitted to special equipment on the ground near the UAV operator. The end result of drone land surveying is a finished map of detail at a given scale, presented in digital format. Surveying drones can fly at much lower altitudes than traditional techniques like manned aircraft or satellites, providing high-resolution, high-precision images faster and cheaper, and independent of weather conditions such as cloud cover.

What are the benefits of drone survey?

Even the most novice user knows that drones can be used for photography. The availability of unmanned aerial photography has led to its use in many sectors and produced incredible images.

Save time and money

The economic advantage of drone land surveying comes primarily from its low operating costs compared to its main competitors, airplanes, and helicopters, which are up to 10 times more expensive than drone topography. Besides, recent studies show drone surveying is up to five times faster than traditional land-based methods.

Provide high data accuracy

Drones have extremely high accuracy, with aerial mapping reaching centimeter-level accuracy and mapping accuracy generally reaching 1:1000. In addition, aerial mapping also has a wealth of 3D geographic information, which can capture the data of large-scale terrain.

Map inaccessible places safer

Drone topographic survey allows us to obtain extensive and reliable data from inaccessible locations, unsafe steep slopes, or hazardous terrain. This means that surveyors can create a 3D computer model of the object under study and take a series of measurements in the office, without necessarily needing to be in the field or in a hazardous area to obtain data.

Monitoring large areas efficiently

JOUAV surveillance drones do tedious and repetitive tasks of monitoring large areas very efficiently and rapidly. With ranges of 30km, 50km, 100km, and 200km, drones can be controlled and maintain a radio/video link over very large distances. The drones have long endurance of up to 12 hours from 60km/h to 140 km/h. JOUAV UAVs have a patrol range of 30 to 100 km and can usually cover the target area in one flight, which is super time and energy efficient.

The easiest and autonomous drones to fly

After pressing the take-off button, the drone takes off autonomously on a planned course, captures images, and then lands where it started. The operator does not need to do anything else during this process.
JOUAV drones also support a Terrain Following Mode based on a high-precision digital 3D map. With this feature, they can automatically generate a variable height route based on the measurement area and maintain a consistent ground resolution for better data results.

Less than 300ms transmission latency for real-time streaming

With a low latency of merely 300 ms, the JOUAV drone security system transmits 1080P HD real-time video, data of the aircraft and its surrounding environment to the ground station through a dedicated communication link. The ground control terminal receives the images and shares the data with other terminals through 4G/5G routers, or it can push the video stream to the cloud server through the network cable. As a result, other mobile terminals can watch the video in real time by accessing the link.

Down to 1cm (0.4 in) absolute accuracy

The JOUAV UAV uses both RTK and PPK modes. RTK is primarily used for precise centimeter-level autonomous vertical landings, and PPK is primarily used to output high-precision POS data to ensure a large reduction in image control points. The JOUAV RTK drone provides best-in-class absolute accuracy with vertical positioning accuracy down to 3 cm and horizontal positioning accuracy down to 1 cm, which allows the JOUAV UAV from high altitude to fly over and still provide low GSD images.
