Digital Photogrammetry Mapping
At Nusail Survey, we specialize in LiDAR (Light Detection and Ranging) data processing, a sophisticated method that leverages laser technology to capture precise, high-resolution data about the Earth's surface and various objects. LiDAR has revolutionized the field of surveying, offering unparalleled accuracy and efficiency in data collection and analysis.
Understanding LiDAR
LiDAR is a remote sensing technique that uses laser pulses to measure distances. These laser pulses are emitted from a LiDAR sensor, and when they hit an object or surface, they bounce back to the sensor. By measuring the time it takes for the pulses to return, the system can calculate the distance between the sensor and the object. This process generates a dense, detailed point cloud of the surveyed area, capturing every feature with remarkable accuracy.
1. LiDAR Data Processing and Classification
Our LiDAR data processing and classification services involve several key steps to ensure precision and reliability:
-
Image Acquisition: Data Acquisition: Using airborne or terrestrial LiDAR systems, we capture high-density point clouds that represent the surface and objects within the survey area.
