Represents a indexed point cloud node in octree.
This class represents a coordinate reference system (CRS).
Base class for handling loading QgsPointCloudBlock asynchronously from a remote COPC dataset.
Base class for handling loading QgsPointCloudBlock asynchronously.
Base class for storing raw data from point cloud nodes.
AccessType
The access type of the data, local is for local files and remote for remote files (over HTTP)
@ Remote
Remote means it's loaded through a protocol like HTTP.
Point cloud data request.
Tile download manager handles downloads of map tiles for the purpose of map rendering.
