uarries present a huge
challenge for industry: when
in use, they are filled with
However, carefully monitoring these
sites is important to the owners of
the quarries. Whether reports for
government or environmental
agencies, or for analyzing the
capacity of the pit, quarry owners
need to know exactly what is going
on with their quarry-turned-landfill.
This was the challenge for a British
quarrying company, where the cost
of inspecting the landfill surface
every few months was costing tens
of thousands of pounds. Properly
surveying the progress in each cell is
mandatory for quarry owners
despite the expense. This is where
Sky Grid came in.
Landfill sites are important to monitor, but it's expensive. Sky Grid uses
Pix4Dsurvey and Pix4Dcloud Advanced to be cost and time-efficient.

material back and forth, which is a
concern for health and safety
regulations. This has made worse
when the quarry is no longer in use or
transitions to focus on a different part
of the site, as it leaves an immense pit
in the ground that people or animals
can fall into. In the UK, one solution
for this is for empty quarries to be
repurposed as a landfill. Waste is
dumped into the hole, providing a
space for the refuse to be stored and
giving some function and regulation
to the space.
