What is Aerial Surveying and Mapping with Drones?
In the realm of geospatial technology, aerial surveying and mapping with drones are transforming many industries. This method involves Unmanned Aerial Vehicles (UAVs), or drones, outfitted with sophisticated cameras and sensors, soaring across a specific geographical locale to collect intricate aerial imagery and topographic data. Once gathered, this information is then meticulously processed and interpreted by specialists in Geographic Information Systems (GIS).
The usage of drones in aerial surveying and mapping has created a seismic shift in the field.

The usage of drones in aerial surveying and mapping has created a seismic shift in the field. Take, for instance, the work of Aerotas, a company that has been leveraging drone technology to deliver high-precision survey data for land surveyors and civil engineers across the United States.
The Technology Behind Drone Surveying and Mapping
At the core of drone surveying and mapping, there are three primary components: sensors, high-resolution cameras, and GPS. Each drone flight is a meticulous mission of data capture, with the drones’ sensors and cameras harvesting raw information with high accuracy across vast swaths of land.
This raw data is then fed into the process of photogrammetry, a sophisticated technique of converting two-dimensional images into three-dimensional models.
Ultimately, the result is a detailed and precise representation of the landscape – a testament to the revolutionary role of drone technology in modern surveying and mapping endeavors.
Benefits of Using Drones for Aerial Surveying and Mapping
The advantages of drone technology in aerial surveying and mapping are manifold: precision, efficiency, safety, and cost-effectiveness all count among the most prominent benefits.
Drones excel under diverse environmental conditions, capturing data from different angles to create high-resolution orthomosaics, thus providing a highly detailed perspective of the area under study.
In contrast, traditional surveying methods often involved significant labor, cost, and time, with results being less detailed and more susceptible to human error.
Drone technology effectively addresses these issues, providing the detailed data necessary for making important decisions.
Consider the solar industry, where a case study showcases the game-changing nature of drone surveying. For large solar farms, drones equipped with thermal imaging cameras and GPS are used to create comprehensive maps of the installation.
These maps can pinpoint inefficiencies or damage, saving time and money in the maintenance and optimization of these vast arrays of solar panels.
Aerial Surveying and Mapping Techniques
The execution of aerial surveying and mapping techniques with drones involves a meticulous process that commences once the drone ascends.
Its sensors and cameras begin to capture data from different angles, a capability enhanced by the drone’s maneuverability and ability to navigate various environmental conditions.
Whether it’s a standard camera for visual data or Light Detection and Ranging (LiDAR) for topographical data, the drone effectively records raw information as it flies over the area of interest.
The ability to survey vast landscapes or intricate urban settings swiftly and accurately is a testament to the remarkable precision of this technology.
After landing, the post-flight phase begins.
The raw data collected during the flight is processed using advanced drone mapping software, transforming it into high-resolution orthomosaics, 3D models, and Digital Surface Models (DSMs).
This valuable information can influence important decisions in industries ranging from urban planning to environmental conservation, such as the case study of solar farms optimizing panel placement based on drone data.
Drone Mapping Software
In general, aerial surveying and mapping cannot be done without using a drone mapping software program.
As the hub where captured data from the aerial camera gets processed, the drone mapping software not only generates high-resolution orthomosaics but also develops complex digital elevation models.
Through the power of algorithms, it seamlessly stitches together images, transforming them into an accurate and comprehensive aerial survey.
GIS professionals heavily rely on this software to make sense of the raw data collected by drones, using it to create models that serve as an essential foundation for further analysis.
In essence, drone mapping software offers a time-efficient means to convert data into actionable insights, thereby serving as an indispensable tool in the field of aerial surveying and mapping.
For example, Pix4Dmapper, one of the leading photogrammetry solutions available today enables users to transform raw images captured during a drone survey into geo-referenced maps or 3D models easily. Another commonly used aerial mapping software is DroneDeploy.
