LIS Virtual
LIS Virtual is designed for efficient access to and processing of very large point cloud collections. Data catalogues combine tiled datasets into virtual point clouds that can be queried and processed as a seamless dataset without manually handling every source tile. Typical applications include managing regional or nationwide LiDAR archives, extracting point clouds for arbitrary project areas independent of the original tile structure, retiling datasets into a new delivery scheme, and generating raster products or thinned datasets directly from large LAS/LAZ, RDBX or SAGA point cloud collections.
