Case Studies

Helicopter-based LiDAR Survey

AAS in collaboration with the Archaeological Institute of Kashihara (Nara prefecture) surveyed tumulus features. A helicopter-based LiDAR system was used to acquire 3D point cloud data that was used to create a digital surface model (DSM) for the tumulus feature. A Red Relief Image Map (RRIM) for the tumulus feature was generated from the DSM. RRIM is a proprietary topographic visualization technology, which was developed by AAS.

Airborne and Mobile LiDAR Surveying

AAS acquired accurate 3D point cloud road surface data using Airborne and Mobile LiDAR systems in order to assess road surface conditions and damages (e.g., cracks, potholes) for MLIT Chubu Regional Development Bureau Mie Office of River and National Highway. Furthermore, AAS proposed a costeffective road management plan based on Airborne and Mobile LiDAR data. read more(Japanese version only. ) →

Seamless Airborne LiDAR Bathymetric and Topographic Data

AAS introduced an "Airborne LiDAR Bathymetry (ALB)"system for mapping shallow sea areas using green laser. Bathymetric suirveys are affected by sudden weather changes, fishing net, shallow water and rapid stream. For example, extremely shallow sea (1-3 meters water) is difficult to survey because ships.Therefore, ALB enables safe, efficient, quantitative measurement of water depth with high-accuracy.
