Module Get Grid from Virtual Point Cloud (interactive)
The module allows one to retrieve a grid from a virtual point cloud dataset by dragging a box (AOI) in a Map View.
Optionally, the query can be constrained by providing an attribute field and a value range that must be met.
A virtual point cloud dataset is a simple XML format with the file extension .spcvf, which can be created with the 'Create Virtual Point Cloud Dataset' module.
