Aerial lidar is commonly used in the construction industry for tasks such as creating digital terrain models, measuring volumes of stockpiles and cut/fill areas, and identifying potential issues with a construction site before work begins.

Aerial lidar (light detection and ranging) is a remote sensing method that uses laser technology to measure the distance to a target. It differs from other forms of remote sensing such as photogrammetry and radar in that it can collect high-resolution, precise 3D data in a relatively short amount of time.

Aerial lidar measurements can be extremely accurate, with typical horizontal and vertical accuracy levels of less than 10 cm. The level of accuracy is dependent on factors such as the density of the point cloud data collected and the quality of the sensor used.

Orthomosaic is a type of mosaic that has been geometrically corrected to minimize distortion and ensure that each pixel represents the same ground area throughout the image. A regular mosaic is a composite image made up of several overlapping images, but it does not have the same geometric correction.

Orthomosaics can be used in construction for tasks such as creating accurate maps, measuring distances and areas, and identifying potential issues with a construction site. They can also be used to monitor progress on a construction site over time.

To ensure that data obtained from aerial lidar and orthomosaics is accurate, it is important to use high-quality sensors and to properly process the data using specialized software. Additionally, ground control points can be used to accurately align the data with known coordinates.
