Day 2 featured a number of presentations involving innovative technology. Airborne LiDAR may be maturing after 15+ years, but in many ways it is still in the early stages of theoretical development. Much research needs to be done on even some of the most basic principles such as a standard method for checking horizontal accuracy and the science behind breaklines.
Here are a few of the highlights from today’s sessions:
- Dr. John Damman from the Army Research Lab presented an alternative method for creating Digital Surface Models that is designed to avoid problems with interpolation
- Dr. Aaron Morris from Allpoint Systems explained how they were able to design an automation workflow that increased the production of LiDAR-derived bridge clearance reports from 20 per person per week to 400 to 500.
- Lewis Graham from GeoCue pointed out that 3/4 of the value of LiDAR data is intensity and that accuracy does not depend on resolution.
- A Joint Airborne LiDAR Bathymetry Technology Center of Expertise has been formed.
- Mike Olsen from Oregon State University reported on the work his team did to survey buildings after the tsunami and earthquake in Japan.
- Dr. Mark Hanus from GeoDigital reported that LiDAR was an effective tool to manage forest fire risk.
- Perhaps the most exciting news is that there are going to be some big breakthroughs in FLASH LiDAR announced in the near future according to Dr. Charles Toth from Ohio State. This could be DOD related.
- Jim Brainard from R.E.Y. Engineers predicted that electromagnetic imaging is going become much more widely used for mapping underground utilities.

I will not be able to attend Day 3, so this will wrap it up. Overall there was a lot of important information delivered and networking accomplished. Everyone I spoke with was very busy. Kudos to the ILMF Team for a great event.
