Road surveying in a quarry site

I’is important to know position of the roads in a construction site.
Especially in an excavation quarry.
Especially if the change quickly.
Especially if it is a quite “vertical“site.

In the Apuanian Alps, North West of Italy, where the White Marble from Carrara is extracted, construction site roads change rather quickly.
They depend on the active parts of the whole quarry.
Their plan is linked to the one of the extraction area.
But they could move slightly away from the project as bulldozers, trucks and dumpers “make” them or “move” those that are already there.

They do not change as quickly as the excavation front, but are nevertheless dynamic entities.
I believe it is important to include them in the areas to be surveyed when topographical activities are made in those sites.

I really don’t feel like saying that you have to use a drone and do aerial photogrammetry at all costs.
Ok, it’s comfortable.
It works well but to detect a road, its borders and its axis, a satellite receiver is fine.
If there are many points to measure, perhaps it is better to use two, in base-rover radiomode.
And the whole job will be done much faster than using just one antenna in nRTK.

Ciao!
