Lidar conversion tool script for ArcGIS 9.3

Chris Harding, Iowa State University

Summary

Python 2.5/2.6 script for converting .las Lidar data files inside a folder into one or more other data formats: ERDAS imagine raster file, TIN (full resolution and decimated), multi-point shapefile (full resolution and decimated version). Script can be run inside a terminal (cmd or Powershell) or can started via an ArcGIS tool (tool is included)

Context

Type and level of course
Anybody who needs to work with the data inside las Lidar files. Several of our grad students have used this script/tool, hopefully it is robust enough for general class use.

Geoscience background assumed in this assignment
none

GIS/remote sensing skills/background assumed in this assignment
Lidar data in general, TINS, multi-point Shapefiles, rasters, TIN decimation, ArcTools

Software required for this assignment/activity:
ArcGIS 9.3 (ArcView license) with 3D Analyst extension. Working Python installation (standard for ArcGIS 9.3 is Python 2.5 but I use it with a Python 2.6 installation as well). Tested on Windows 7, should run on XP as well

Time required for students to complete the assignment:
N/A
