Abstract
A method comprises accessing a data set comprising a LIDAR acquired point cloud comprising a plurality of points each of which are attributed with at least a geospatial coordinate, sub-sampling at least a portion of the plurality of points to derive a representative sample of the plurality of points and displaying the representative sample of the plurality of points.

A method comprising:
- accessing a data set comprising a LIDAR acquired point cloud comprising a plurality of points each of which are attributed with at least a geospatial coordinate;
- sub-sampling at least a portion of the plurality of points to derive a representative sample of the plurality of points;
- and
- displaying the representative sample of the plurality of points;
- wherein sub-sampling at least a portion of the plurality of points comprises dividing a volume represented by the point cloud into sub-volumes and assigning a value to each of the sub-volumes, and
- wherein the assigned value of each sub-volume is indicative of a number of points inside the sub-volume.
