so just to be clear, you're speaking about the shift from going analog to digital capturing of the data?

Yeah, but also the way how GPS surveying was enabling the industry for measuring long distance.

It was not easy before to measure long distance with a high accuracy, which changed immediately when the satellite navigation system came into place and we were able to measure long distance with the GPS system.

And so this was a shift which gave us a push in the surveying industry on getting new distances and areas measured.

And this was a change.

A lot of people at that time thought, okay, it's the one and only and the other technology will not use anymore, but you will find the limit in the GPS surveying at that time when you run into a tunnel then immediately you will have no satellite signal and no satellite signal means no position on the ground.

So it was again saying at the end it was a very good tool and technology which was an add-on to the existing one and gave new opportunities on surveying.

Okay, we are speaking about Intergeo, but since you have so many experiences with also different trade shows as an exhibitor or later as an organizer, I'm interested in like, where do you see the biggest mistakes of exhibitors or of like exhibitors to be like, what do they get wrong about exhibiting on on expo or what wrong expectations do they have?
