Coordinate system of .las file?

I have uploaded a set of geotagged images to Pix4D mapper cloud. In the online viewer, I can see that the 3D reconstruction of the property is set at the correct GPS location.

I now need to get the digital elevation model of my map. For this I have downloaded the .las file. I can parse it with my own C++ parser or look at it with

I’m confused about the coordinate system of the data points. They are around 459262.316139 5245125.344528, 565.579197, whereas the GPS coordinates should be around 47.35, 8.46, 500.0 (very roughly).

Very helpful, thanks!

Is there a way of seeing in which UTM zone the points are in the .las file?

You can see it in the quality report.
