Tool Create Virtual Point Cloud Dataset
The tool allows one to create a virtual point cloud dataset from a set of SAGA point cloud files. For a large number of files, it is advised to use an input file list, i.e. a text file with the full path to an input point cloud on each line. If possible, you should make use of the point cloud headers files to construct the virtual dataset. This avoids that each dataset has to be loaded and thus reduces execution time enormously.
A virtual point cloud dataset is a simple XML format with the file extension .spcvf, which describes a mosaic of individual point cloud files. Such a virtual point cloud dataset can be used for seamless data access with the 'Get Subset from Virtual Point Cloud' tool.
All point cloud input datasets must share the same attribute table structure, NoData value and projection.
