Terrestrial LiDAR= The best way to get a dense data scaffold in the field-

if it could be adapted for rapid deployment in uncertain

environments…

•Weight•Electricity•Time•The Unexpected

Using LiDAR in the Field…

TEST CASE 2011 Khirbat Faynan, Jordan

*testing the engineering

*creating metadata standards & workflow

*building a digital scaffold

Scan Planning

•Pre-Plan: Size, Schedule, Power, Transport..

•Trouble Shoot the Landscape

•Re-Assess the Plan & Prioritize

•Scan, Scan, Scan

•Scan

•Keep up your Labeling Systems

•Keep visual & textual Metadata throughout
