You need to download and place the pointclouds data into the /static/pointclouds/highres.
The structure looks like:

Upload the PointCloud data in cloud storage

• You need to have installed locally gsutils
• log in you google account to get writing permissions
• Navigate to the root where the data folder is placed and start the copy of the files to the google cloud storage:

gsutil -m cp -r ./data gs://via-appia-20540.appspot.com

Enable settings locally

You can change local setting by creating a .env file and enabling the settings you want to have:

Converting big LAS files to LAZ and viewing it in Potree Desktop

To make things easier you can use windows. it is possible to compile the PotreeConverter and LasZIP for Linux and Mac but you have to do it yourself.

What you need:

• Your LAS file, (in our case has been a 17GB size file).
• PotreeConverter
  • Download here PotreeConverter_1.7_windows_x64.zip
• Potree Desktop (optional, use it to test your converted files)
  • Web: https://github.com/potree/PotreeDesktop/releases/tag/1.8
  • File: PotreeDesktop_1.8_windows_x64.zip

Only PotreeConverter 1.7 is able to compress the LAS files. It will result in many small files. PotreeConvert 2 only uses one file, but it doesn't compress, so the resulting point cloud will be as big as the original LAS.

Navigate to the folder where PotreeConverter is, and run the command (replace the <names>):

./PotreeConverter.exe .\<fileName>.laz -o ./<outputDirectory> --output-format LAZ

Once the process has finished, you can drag and drop the new output directory to PotreeDesktop 1.8.
