Construction sites (often) mean moving vehicles.
They need to travel in order to bring materials and remove debris and waste.
Even if vehicles are not so heavy, tires on the pavement of a historic center, in the long run, can damage it.
Here’s below one of the outputs of an aerial photogrammetric activity that I was assigned to do in the historic center of my home town, Sarzana – Italy.
Trucks needed to travel back and forth to reach a construction site.
I used a drone to take nadiral pictures of the entire road.
I shot them in order to have 70% of overlap between two sequential photos.
Then I processed them in a photogrammetric software.
I measured the coordinates of a bunch of points there were recognizable in the pictures (without going crazy on their quantity and disposition on the ground).
I used them to georeference, scale and orient the model.
In the end I generated an orthomosaic and loaded over the available 2D cartography of the area.
I thought that it was a good idea to show the footprint of some photos.
Of course not all the pictures taken and processed were shown but just the ones there were able to cover the entire path.
I added the filename and delivered a folder with the original jpg high resolution files.
Even if the orthomosaic is super detailed, thanks to the single images you can provide an extra tool for analysing the road.
After all these things have been done the state of the pavement was “frozen” before the activities started and trucks began to travel.
This ensured the Municipality for possible damages to charge but also ensured workers for not being charge due to damages they didn’t actually cause.
