This research paper will compare and analyse the survey from two methods of Remote Sensing techniques, Terrestrial LiDAR used as the base survey, and UAV Photogrammetry as the comparison survey for use in Landfill volume reporting.

Managing landfills generally requires adherence to local Environmental laws, and as such can include reporting on key metrics about the site including waste volume increase and remaining airspace in waste cells – important in end of cell life management and relaying on-costs to site users. These surveys have traditionally been recorded manually using GNSS GPS or Total Station techniques which can be dangerous to survey staff – oftentimes being exposed to the landfills harmful waste material. Remote sensing may be able to provide better data, faster, cheaper and eliminate exposure to harmful waste.

While extensive research has been undertaken in comparing UAV Photogrammetry to many other forms of survey, there is little research specific to the waste management context, and the advantages of remote sensing for workers.

This dissertation aims to research, test, and evaluate the suitability of UAV photogrammetry for the purpose of landfill volume survey for safety, cost, efficiency, and quality of delivered outcomes for their use in site management. Assessment of how the objectives are met will be done with quantitative analysis – providing a comprehensive cost-benefit analysis and quality assessment of each system output.

A control site was selected at the Albury Waste Management Centre – Operated by AlburyCity Council which are also the project sponsor. Two surveys were conducted on two separate time-series to build up a dataset able to produce a comparison of the methods.

UAV Photogrammetry – for its simplicity, low cost, and safety advantages, should be utilised by local government and landfill operators.

The study showed that UAV photogrammetry was able to survey far greater areas in a similar time, while significantly reducing time spent on site and drastically reducing exposure to the site waste.

For the great benefits and its demonstrated accuracy UAV photogrammetry can be deemed sufficient for volume survey in the waste management context. The UAV method being less costly, still maintained a +/- 120mm relative accuracy to the base survey, which far exceeds the minimum EPA Waste Levy Guidelines of +/- 200mm.
