I have many XYZ Lidar files which contain the class code prior to the co-ordinates i.e. 2 x y z. How can I import this file and convert it to multipoint?
I may be wrong, but don't know of way within ArcGIS to pull class codes into a multi-point from an ASCII file. You can probably do it in a stand-alone python program using the liblas library of python LAS processing tools, to create LAS files with class code, then pull them into multi-points using the 3D Analyst LAS-to-Multipoint GP Tool http://www.liblas.org/tutorial/python.html
