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 [http://lidarview.com/](http://lidarview.com/).

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).

How do I convert what I am getting from the `.las` file to LLH?

Some posts on here mention setting the right coordinate system for exporting, however I don’t see any such option in the cloud version of Pix4D mapper.

Thanks!

Hi Nick, This might be relevant to you: [https://support.pix4d.com/hc/en-us/articles/215858503-Cloud-general-questions#label8](https://support.pix4d.com/hc/en-us/articles/215858503-Cloud-general-questions#label8), To get the output in the coordiate system , you want, you will need to define the output coordinate system (select in Pix4D desktop) and the upload from desktop: [https://support.pix4d.com/hc/en-us/articles/202558589-How-to-upload-project-files-from-Desktop-to-Cloud](https://support.pix4d.com/hc/en-us/articles/202558589-How-to-upload-project-files-from-Desktop-to-Cloud)

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