How Does Airborne LiDAR Survey Work?Airborne LiDAR survey is a survey technique that uses lasers to measure distances and capture data in challenging environments. The process of airborne LiDAR survey involves three distinct steps: data collection, data processing, and data analysis.
Data collection is the first step of an airborne LiDAR survey and involves the use of a laser scanner mounted on an aircraft to scan the area of interest. The laser scanner emits pulses of light which are then reflected back to the aircraft by the terrain or objects in the environment. The data collected is then stored in a computer which is used to create a 3D map of the area of interest. Once the data has been collected, it must be processed in order to be useful.
During this step, the data is filtered, cleaned, and transformed into a format that can be easily analyzed. This includes removing noise from the data, such as trees or buildings that may have been captured during the scan. The data is then converted into a point cloud which can be used for further analysis. The final step in an airborne LiDAR survey is data analysis.
This involves using specialized software to analyze the point cloud and generate accurate results. This analysis can be used to measure distances between points, calculate elevation changes, and generate precise 3D models of the area of interest. Data analysis can also be used to identify areas that need further investigation or that may require additional surveys.
