- You can use a software like LAStools to extract a subset of the point cloud data that you're interested in.Firstly,Using laszip function we can reduce the size of the LAS file. Then using a function called lasclip you can clip the file to a specific area.
How to read/pre-process too large las file?

Hi everyone,
I have a las file of 50GB and I want to read/load it in MATLAB ( I have the lidar toolbox available).
I have a Mac from 2017 and it's just not able to handle such a file.
Is there a way to pre-process the las and/or reduce the size by selecting a subset of the area?
filename = '/LiDAR/lidars/terra_las/cloud_merged.las';
lasReader = lasFileReader(filename);
ptCloud = readPointCloud(lasReader);
Thanks a lot for your tip/suggestions.
