Falcon Survey Engineering Consultants, UAE, is one of the leading organizations in the field of Lidar Mapping. This includes the process of collecting geospatial data from a mobile vehicle, typically fitted with a LiDAR + Camera systems. Such systems are composed of an integrated array of time synchronised navigation sensors and imaging sensors mounted on a mobile platform. The primary output from such systems include GIS data, digital maps, 3D models and georeferenced images and video.
LiDAR (Light Detection & Ranging) is a remote sensing technology, works in a similar way to RADAR and SONAR yet uses light waves from a laser (1 Million Pulse Per Second), instead of radio or sound waves. A LiDAR system calculates how long it takes for the light to hit an object or surface and reflect back to the scanner. The distance is then calculated using the velocity of light. These are known as ‘Time of Flight’ measurements. Differences in laser return times and wavelengths can then be used to make digital 3-D representations of the terrain. Lidar sometimes is called 3D laser scanning.
LiDAR mapping uses a laser scanning system with an integrated Inertial Measurement Unit (IMU) and GNSS receiver which allows each measurement, or point in the resulting point cloud, to be georeferenced. Each ‘point’ combines to create a 3D representation of the terrain. LiDAR systems are most commonly used for surveying tasks. Because of their ability to collect three dimensional measurements, laser scanning systems are popular for surveying the built environment (such as buildings, road networks and railways) as well as creating digital terrain (DTM) and elevation models (DEMs) of specific landscapes. LiDAR maps can be used to give positional accuracy – both absolute and relative, to allow viewers of the data to know where in the world the data was collected and how each point relates to objects terms of distance. LiDAR data, in the form or a point cloud, can be used to map entire cities, enabling decision makers to accurately pinpoint structures or areas of interest in millimetre perfect detail. Features and objects such as road networks, bridges, street furniture and vegetation can be classified and extracted. LiDAR maps can also be used to highlight changes and abnormalities such as surface degradation, slope changes and vegetation growth.
