A point cloud is an unstructured set of points, each defined by x,y,z co-ordinates.

A point cloud is an unstructured set of points, each defined by x,y,z co-ordinates. They are commonly produced as the raw data form output by laser scanner (LiDAR) systems although other forms of spatial mapping can also produce point-clouds (e.g. photogrammetry). The LAS file format is an example of a commonly used structure for storing point-cloud data. Analysis of point-cloud datasets require a unique set of spatial analysis algorithms compared with other forms of raster or vector geospatial data.
