It often happens that I read technical specifications that request a survey service by specifically indicating the use of a certain technology or instrument, rather than focusing on the expected results.
“We need a survey with a drone” is one of the top phrases that bothers me a bit.
It doesn’t mean anything since a drone is not a measuring instrument.
“You need to do an aerial photogrammetry survey because we need a point cloud.”
Wait, a “mobile mapping” system also gives you a point cloud.
“Laser scans must be carried out with instruments of a million points per second.”
Really? For a 1:500 scale plan?
I realize that sometimes very important information, such as output accuracy, scale of representation, reference systems, and the purpose of the work, is often overlooked.
In the end, a survey solves a problem.
But the problem can vary greatly from case to case.
It is important to communicate it in detail, so the technician can choose the appropriate instruments and, consequently, the right process.
I would be happy to know that a geomatics or surveying consultant has supported the staff in drafting a technical specification, or in evaluating the offers received.
Here in Italy is something we still have to work on...
