Future development in LIDAR-derived DEM workflows market requirements, paths for 3 rd-party developers Speed – but can be overcome with more CPUs Black box – minimizing human interaction, especially during the filtering and editing stages; possible impact of Full Waveform Digitizing (FWD) LIDAR data on accuracy and ability to filter data Multi-sensor automation - easier fusion from dissimilar sensors – airborne LIDAR + terrestrial LIDAR, LIDAR + airborne (Vis or NIR) imager, LIDAR + thermal imagery Auto QC – automating the quantitative measurement of output data quality 8
