Landfill Area and Volume Study

For this project, aerial photogrammetry and 3D point cloud model capture were required to review available material deposit areas and volumes in a waste disposal landfill in Hong Kong.

The landfill management company required an accurate 3D model and map of the entire site, so Dronesurvey Asia employed an Emlid RTK/PPK system in conjunction with a Phantom 4 Pro to photograph the entire site to within 1.4cm XYZ accuracy, and a GSD of 2.5 to 3.0cm/px. From this, a detailed orthomosaic map and Digital Surface Model (DSM) were generated, and used to accurately determine area and volume measurements from various earth and refuse deposits within the site.

A 3D model was also generated for reference. Together, this gave the client a complete, accurate, and up-to-date picture of the landfill area for ongoing evaluation.
