Aerial Survey: Do You Know the Mapping drones? 

Estimated reading time: 5 minutes

With the continuous advancement of technology, aerial survey and mapping drones have transformed our perspective of the world. They provide us with a fresh outlook and play an increasingly crucial role in various fields such as land surveying, urban planning, and environmental monitoring.

Getting Started with Surveying Drones:

What Is a Surveying Drone?

Surveying drones are unmanned aerial vehicles equipped with various sensors and cameras capable of executing diverse surveying tasks, including map creation, 3D modeling, and environmental monitoring.

What Can Surveying Drones Do?

Surveying drones efficiently and accurately gather geographic information data, rapidly generating high-resolution maps and models.

Their applications span across multiple fields, including land surveying, forestry management, urban planning, and disaster monitoring.

Why Choose Surveying Drones Over Traditional Methods?

Compared to traditional surveying methods, surveying drones offer advantages such as lower costs, higher efficiency, and superior data quality. They can quickly cover extensive areas and perform tasks in different terrain conditions, providing users with more comprehensive and detailed information.

Grasping the Technology: Core Features of Surveying Drones:

Flight Performance of Surveying Drones:

The flight performance of surveying drones is a core feature. Flight altitude determines data collection accuracy, while flight speed directly influences task execution efficiency.

Additionally, hover capability is a critical indicator, especially for tasks requiring detailed surveying in specific areas. When choosing surveying drones, users need to consider these flight performance parameters based on task requirements and environmental conditions.

Understanding Various Sensors:

The sensors onboard drones directly determine the diversity and quality of data collection. RGB cameras are suitable for general map creation, while infrared cameras can be used for vegetation monitoring in agriculture.

Furthermore, sensors like LiDAR provide highly accurate terrain data. Understanding the principles and suitable scenarios of different sensors helps users select the right drone based on task requirements.

Introduction to Flight Time and Route Planning:

Flight time and route planning directly impact a drone’s endurance and task execution efficiency. Longer flight times mean greater coverage, especially beneficial for large-scale surveying projects, reducing the frequency of landings and battery replacements, thus improving work efficiency.

Route planning ensures an optimized path, automating the entire task and ensuring the integrity of the coverage area. This is crucial for reducing human errors and enhancing data consistency.

Careful Selection: Brands and Models:

Brief Introduction to Well-Known Surveying Drone Brands:

In the market, DJI stands out as a leading brand, receiving acclaim for its Phantom, Inspire, and Mavic series products. Parrot’s Anafi series is renowned for its lightweight and high-performance features.

HEQ, with a focus on fixed-wing drones, has introduced the SWAN fixed-wing surveying drone, providing unique solutions for specific tasks. Understanding the characteristics of these brands helps users make informed decisions when choosing a drone that aligns with their requirements.

HEQ’s Mapping Drone:

HEQ is an emerging manufacturer of fixed-wing drones. The HEQ Mapping drone features vertical take-off and landing, with a one-key switch flight mode function. It boasts an impressive endurance of 50–60 minutes and a flight speed ranging from 10m/s to 25m/s.

The HEQ Swan Mapping drone incorporates non-rudder control technology, enabling simple operation and achieving centimeter-level mapping accuracy.

After the flight mission is over, surveying and Mapping Data Processing

1. Data Analysis:

After converting the static data collected in the field survey into a Rinex file, import them into YFI gama solving software with the data in PPK together for data Calculation.

2. Data Processing:

01:Compare and process the photos taken during aerial operations with the corresponding POS (positioning) data, eliminating redundant and unusable data, ensuring a one-to-one correspondence between photos and POS data.

POS Data

02: Convert image control point data into a CSV file that can be imported into modeling software.

Data for ground control points

3. Photo Processing:

Import processed photos, POS data, and ground control point data into mapping software for resident mapping.

Tips: Data calculation and mapping process reference data processing tutorials and corresponding mapping software tutorials.

Understanding of regulations:

When selecting and using surveying drones, it is very important to understand the relevant laws and regulations. There are international regulations for flying drones, so make sure your operations are legal.

Protecting privacy is equally important as ensuring flight safety. It is your responsibility to understand the privacy regulations relevant when flying, and to take appropriate security measures when using a mapping drone.

Conclusion:

When choosing a survey drone, it is crucial to fully understand your needs, understand the different options on the market, and pay attention to technical characteristics and regulatory requirements.

We hope that through the introduction of this article, readers can more confidently select a surveying drone that suits their needs and start a drone adventure of their own.

HAPPY FLYING!
