Lightning Talk: Working with
LiDAR Data
April – June 2013

LiDAR data manipulation
 Derive Ground to Tree Heights
 Approx. 9Gbytes LiDAR LAS data in original dataset
 Combine Point Cloud LAS files
 Clip Point Cloud & Roads to AOI (Area of Interest)
 Filter Point Cloud by elevation – thin bad returns
 Tile the point cloud into “cells” (i.e. 10x10m areas)
 Split by Classification (Ground & High Vegetation)
 Convert Point Cloud Cells -> multi-point
 Extract Min/Max XYZ and calculate maxZ-minZ = diffZ
 Output to:
 Coloured polygons (MapInfo)
 Source:
LAS LiDAR
GeoBase
- National Road Network
 Result:
MapInfo TAB
