LIS Virtual - massive point cloud data processing

This package contains tools to create and manage data catalogs (virtual point clouds describing a mosaic of point cloud data sets). Data catalogs provide seamless data access for data dissemination and mass data processing. This includes tools for spatial subset extraction (clipping), retiling, gridding and thinning. Data catalogs can be created from SAGA point clouds, LAS/LAZ files or Riegl RDBX files.
