Dear all
I have a dense point cloud (.Las) which is consist of 150 million points and I want to create a Raster file (i.e., DSM) from it. The question is: which software can do it? I used the LASTools, ArcGIS and TerraSolid, however; none of them could handle such a big file.
Thank you in advance,
Did you try FUSION? If it is still too big, you can tile your data and build DSM using a list of tiles as a batch file.
Dear the best to you use software is called eD3, and if you need any help just ask
regards
Dear If you could not do it you can send me your data and I will do it DSM to you.
Regards
I would recommend the LAStools software distributed by Rapidlasso (free and commercial versions) that is specially designed to work with large clouds of 3D points.
Sayyed, you can do this with Terrascan for sure. You have to split your data in tiles that fit in your RAM and TScan provides tools to do that. Reading one point from each 100 you can find the extent of the point cloud. Then define a project, draw the blocks of the project and distribute the points into blocks. The DSM can be generated as a project command. Read the TScan documentation.
Dear all
Thanks for your answers. They were helpful.
I recommend using Cloud Compare (link at the end). It's a free software that I used for large point cloud files. One of my study sites has over 237 million points (11 LAS files). I used Cloud Compare to merge them into one, then export them. You have a few options for your export file type and format.
One more important detail, the processing for the above-mentioned dataset was done in a MacBook air (early 2015) with a 2.2ghz i7 processor // 8GB ram // and SSD drive.
link to cloud compare (available for windows, linux and MacOS):

Good luck.
