Processing point cloud data#

Beagle use Hadoop map-reduce for processing point cloud data, read data from HDFS, generate LOD PCD.
Old documentation confluence - Beagle data storage model and implimentation

Procedure:#

Upload file to HDFS:#

For text file you can upload to HDFS directly. See how to upload
For las/laz file you have to split your data first ( <4000000 points for each), then upload splitted data.
Run hadoop map-reduce job

Split files#

You can use lassplit to split las/laz files

lassplit "D:\<folder_name>\*.las" -merged -split 4000000 -o ./<file_name>.las

Run hadoop map-reduce job#
