Slide showing an oblique view of a UAV-enabled 3D model of a landfill at two different times


Sample Description

(1) Course Name/Type: CE 176: Environmental Geotechnics, upper level elective course in a 4-year civil and environmental engineering curriculum

(2) Course Emphasis: solid waste management, landfills, remediation

(3) Descriptive Title of Sample: Slide showing an oblique view of a UAV-enabled 3D model of a landfill at two different times

(4) Brief Teaching Note:

Unmanned Aerial Vehicles (UAVs) can be used to monitor landfills. Using LIDAR or optical data and the Structure-from-Motion technique, three dimensional models of the landfill can be created. By taking the difference between 3D models, one can measure the volume of placed material, or the amount of settlement and back-calculate settlement rates as shown in Champagne et al. 2023.

The attached slide shows an oblique view of a landfill in Greece as observed by UAVs deployed in July 2019 and December 2019. A sliding window is used to illustrate the differences between the two dates. Visually, one can observe the areas of activity and especially areas where waste material has been placed. For every pixel that you see in this photo, there is an x, y and z coordinate. In addition, as shown on the second slide, the difference in elevation between the two volumes can be measured, allowing for an estimation of waste material placed as well as areas where material was excavated or waste settlement has occurred.

Data shown was collected in collaboration with John Manousakis, ARGO-E Group, Athens and Prof. George Athanasopoulos, University of Patras
