Chapter Content
• GNSS-equipped drones perform aerial mapping
Detailed Explanation
GNSS-equipped drones, also known as UAVs (Unmanned Aerial Vehicles), use Global Navigation Satellite Systems to determine their precise location while flying. This allows them to capture accurate images and data from the air. Aerial mapping refers to the process of collecting data from above the Earth’s surface using these drones, often replacing traditional methods that require much more time and manpower.
Examples & Analogies
Imagine a bird flying over a city, taking pictures of different landmarks. Just like the bird is able to see everything from above, a GNSS-equipped drone can collect high-resolution images from the sky, helping engineers or planners to visualize areas that might be difficult to access on foot.

Chapter Content
• Used for volume estimation, terrain modeling, progress monitoring
Detailed Explanation
The integration of GNSS with UAV technology allows for several important applications in civil engineering and land management. Volume estimation involves measuring the size of stockpiled materials or excavations. Terrain modeling creates a three-dimensional representation of the land surface, which is crucial for planning infrastructure projects. Progress monitoring enables project managers to track development over time and ensure that everything is on schedule.
Examples & Analogies
Think about a construction site where big piles of dirt are being moved. A drone can fly over the site and quickly measure how much dirt was removed or added, giving contractors a clear picture of the project's progress without having to manually measure everything. This saves time and helps keep the project on track.
