Wzgórze Maślickie: volume measurement on large site

Wzgórze Maślickie – an artificial hill 157.4 m above sea level located in the residential area of Maślice in Wroclaw, Poland. It is a reclaimed landfill operated from the 1960s until 2000 and covers an area of 14 hectares. It is the highest point in Wroclaw.

On our day off, we decided to make a 3D model of this abandoned landfill and check the amount of garbage stored there. The survey was carried out with the DJI Mavic 3E RTK in automatic oblique mode. 636 photos had to be taken to create a 3D model in Agisoft Metashape.

Even though Sketchfab distorts the quality of the model a bit, the result is beautiful. Of course, it looks much better in specialized software!

Digital elevation model and landfill volume measurement

We conducted the survey using a GSD resolution of 2 cm/pixel, which provides sufficient accuracy for our volume calculations.

To calculate the volume, we created a polygon at the visual foot of the hill. Using the volume calculation function of Agisoft Metashape, we obtained the volume value. The data is shown in the table below:

We also built cross-sections on understanding the nature of the relief:

Finally, I would like to add that the photogrammetric method is more accurate, faster, and less time-consuming compared to the traditional method of calculating volumes in large areas.
