Hi Bernd.It sounds like the data were acquired and processed with Trimble
hardware and software. I am not familiar with their products however they tend
to write proprietary files unless they are exported to a open data format
within the Trimble Procesding software. I will have a look at ghd standards
when I have a few moments. As the data are kased scans, Agrisofglt or Pix4d
software are not suitable as these aed I are based, structure from motion
solutions.Kirk SchmidtSent from my Galaxy

Data? Hi Richard,wow, this is amazing stuff in the video!For the type of things
I am doing, this solution would be quit sufficient.I think the data I received
is way too detailed, but I'll try to get intouch and ask them to convert it to
.las if possible.Thanx a lot for all the hints!BerndOn 26.03.21 10:38, Richard

for you , you would have needed to receive the scan data in LAS format, it
would appear that the rcwx files are proprietary format from Trimble, and are
Trimble RealWorks Project files. The Pointcloud data is in the .tzf files Can
you ask the provider of the data to export the scan data as a LAS Format File?
You should then be able absorb the data into an Open Source Stack i.e.....Cloud
