In order to capture the best result with REVO systems it is important to:
- End the scan at the same place where started;
- Create internal loops whilst scanning
Going in one direction and then following your footsteps back is not the same as closing the loop from a different direction.
By closing a loop, you are making repeated measurements of the same area but the error is NOT spread in the same way around the loop.
The longer the scan length without closing a loop, the more absolute error will be created.
