Hello, How can i get a Point Cloud from the whole Area?

gfacciol commented 2 years ago

Yes, you can joint all the ply in a single point cloud. However, the ply format is not adapted to handle billions of points, so instead we use a potree. The script utils/s2p_to_potree.py should do the job:

I need it in the LAS Format to process with danesfield. That's why i want to merge them.

I'm not aware of a single tool that would do the conversion, but I think it should be easy to script as:

1st: convert all ply to las using plyfile and laspy to read and write each file https://github.com/dranjan/python-plyfile https://github.com/laspy/laspy

2nd: merge all the las files using lasmerge https://rapidlasso.com/lastools/lasmerge/
