CPD: Understanding multi-sensor positioning systems

1: What best describes the difference between total station and GNSS surveys?

Total stations are traditionally based on local coordinates while GNSS works mainly on national coordinates but can access local coordinates when needed
Total stations are only ever for small projects while there’s only ever a need for GNSS on complex sites
Both are the same, there are no differences in the coordinates they provide

2: True or false: RTS systems do not require a clear line of sight to targets?

3: Which of these is a downside to only using GNSS systems?

They still require reflector points, which isn’t always possible on more complex sites
They are outdated and the technology is often inaccurate
They require line of sight to the sky and cannot be used indoors

4: True or false: certain construction site standards now require a national coordinate system?

5: Which of the following is not a reason that construction sites need to adopt digital tools and workflows?
