Aerial LiDAR acquisition begins with careful mission planning, where flight lines, altitude, pulse density, and sensor settings are tailored to meet the accuracy and coverage requirements of each project. Aircraft are equipped with LiDAR systems integrated with high-precision GNSS and IMUs, ensuring accurate position and attitude data are recorded throughout the mission. As the aircraft flies its planned lines, the sensor emits thousands of laser pulses per second, recording the time and angle of each return to compute precise three-dimensional coordinates across the project area.
Once collection is complete, raw point clouds undergo post-processing including trajectory computation, point cloud generation, and calibration adjustments to ensure geometric accuracy. Our team classifies the data into ground, vegetation, and structure categories, enabling extraction of bare-earth terrain models, canopy metrics, and surface models tailored to project needs. Quality control checks are performed to verify that vertical accuracy and point density requirements are met before delivery.
Final deliverables can include classified LAS files, digital terrain and surface models, intensity imagery, and contour datasets compatible with GIS and CAD platforms. Our end-to-end workflow, from flight planning and collection through processing and delivery, ensures a streamlined experience for projects of any scale. Aerial LiDAR is well suited for topographic mapping, corridor surveys, floodplain analysis, forestry assessments, and any application demanding precise, high-density elevation data over large areas.
