Aerial Mapping & Drone Surveys

Unmanned Aerial Vehicles (UAVs) technology has been around for nearly a century, but it certainly wasn’t used in the way we see them used today. As the technology continues to evolve, AUAV continues to stay in step with the ever-changing scope.

At AUAV, we use unique skills and advanced equipment to bring customers a first-class aerial surveying and mapping experience. AUAV strives to provide superior quality aerial drone surveying and mapping services with highly accurate topographic maps and centimetre-level accuracy at any given time.

Equipped with high-end surveying drones and a crew of skilled surveyors, we deliver results faster, enabling our clients to make agile decisions much more quickly.

The resolution of our maps and survey data is usually between 1- 3cm per pixel (1-3cm GSD). We process the data to deliver full 3D terrain models (e.g., DSM, DTM), and the accuracy of the 3D data is generally around 50mm horizontal and 50-80mm vertical.

What is a Drone Survey?

A drone survey uses drones to capture data with the help of downward-facing sensors, such as LIDAR payloads, RGB, or multispectral cameras. A drone survey with an RGB camera photographs the ground several times from various angles, and each of these images is tagged with coordinates.

A photogrammetry software uses this data to create geo-referenced orthomosaics, 3D models, or elevation models of the project area. Using these maps, information such as volumetric measurements, areas, slope and high-accurate distances can be extracted.

Unlike satellite imagery or manned aircraft, drones have the ability to fly at a much lower altitude, capturing high-resolution and highly accurate data at a much lower cost.

What is Drone Mapping?

Drone mapping is an innovative technique that leverages the power of survey drones to collect aerial images and generate detailed maps and models. This advanced approach to surveying and mapping has revolutionized how data is collected and analyzed in various industries.

The core of drone mapping lies in its ability to collect aerial images of land surfaces and structures. Equipped with high-resolution cameras, drones capture a series of overlapping images from different angles, covering extensive areas with ease and precision.

Drone Survey Mapping goes beyond mere photography. The images captured by survey drones are processed using specialized software to create comprehensive maps and 3D models. These maps are used for a variety of purposes, including land surveying, construction planning, environmental monitoring, and more.

Survey drones are specifically designed for mapping purposes. They are equipped with advanced sensors and GPS technology, enabling them to navigate and cover targeted areas effectively. Their ability to reach difficult or inaccessible terrains makes them an invaluable tool for comprehensive land surveying.

Drone mapping is a technologically advanced method that transforms how aerial images are collected and utilized for accurate measurements and detailed survey mapping. At AUAV, our expertise in drone mapping provides clients with precise, efficient, and comprehensive data, essential for informed decision-making and effective project management.

Why Use Drone Surveying and Aerial Mapping?

Some benefits of using drone surveying and aerial mapping include:

Provide Accurate And Reliable Data A single drone flight can produce thousands of measurements. These can easily be represented in different formats such as point cloud, DTM, contour lines, DSM, orthomosaic, etc. Each pixel of the aerial map or point of the 3D model contains 3D geo-data.
Provide Accurate And Exhaustive Data Quickly An aerial surveying drone captures huge amounts of survey imagery and data of complex and large projects in a short period of time. Aerial surveys are great for reporting quantities and conformance.
Ability To Map Inaccessible Areas Aerial mapping drones are limitless. They can fly almost anywhere – unreachable areas, unsafe steep slopes, or harsh terrain unsuitable for traditional measuring methods.
Safely Track The Progress Of Your Project Drones give you the ability to monitor the progress of your project from a distance. This is a big step towards a more efficient and safer monitoring process.
