intro
Welcome to a special "magazine issue" of LiDAR News. In this issue we highlight the articles from our recently published LiDAR Magazine. As many of you know not only did we publish a digital edition of the third issue of the magazine, but for the first time we published a print edition, which was distributed and well received by those attending ILMF 2012. If you would like to receive a print version please use this form to subscribe.
For those who were not able to attend I wanted to take this opportunity to do a brief recap of some of the highlights of IMLF 2012. The conference unofficially opened with the ASPRS - American Society of Photogrammetry and Remote Sensing Hot Topics session. Lewis Graham from GeoCue, the LiDAR Division chair discussed the recently approved LAS 1.4 data format and the work that is being done in the Mobile Mapping committee on a best practices manual.
Of note was the fact that none of the vendors are shipping software that supports 1.4 - yet, and perhaps as importantly there is no file validator software available or planned. In fact, the ASPRS has not offered reference implementations of any of the LAS formats.
The other unresolved issue that came up during the ASPRS session was the fact that there is no standard or accepted method for checking the horizontal accuracy of an airborne LiDAR data collection. Based on a few informal discussions, I think both of these items will be receiving follow on attention.
An extensive market research study was one of the plenary session topics. It was conducted on behalf of the USGS by Dewberry to analyze the benefit/cost ratios of establishing a National Enhanced Elevation program for the U.S. At levels of 1 to 2 LiDAR points per square meter or greater density and virtually any reasonable revisit schedule the benefits outweighed the costs typically by a factor of 4 in most cases. The problem is where to get the upfront money to fund this national LiDAR program.
As an alternative, the Oregon Department of Geology and Mineral Industries - DOGAMI LiDAR program, the other plenary presentation, is demonstrating that innovation and the entrepreneurial spirit is alive and well in state government as they slowly, but surely obtain LiDAR for the state. Data distribution has been their one challenge. Anyone interested in helping them?
There were a number of excellent presentations updating attendees regarding ongoing research into bathymetric LiDAR, better methods for creating digital surface models, full waveform analysis, breaklines, single-photon detection and more. Dr. Habib presented a very encouraging set of results indicating that a much less rigorous mathematical approach to LiDAR system calibration holds promise.
Perhaps the least well kept secret at ILMF 2012 was the rumor that a major breakthrough in flash LiDAR might be around the corner. Dr. Charles Toth referred to this in his single-photon research presentation. I have a sense this may be coming from DOD research that might now become public. A couple of impressive workflow automation sessions involving the production of bridge clearance reports by Allpoint Systems and sign extraction by Earth Eye demonstrated that automated feature extraction, at least on a limited basis is making real progress.
In general ILMF has its roots in airborne LiDAR, but like SPAR it is also pushing into mobile. One of the more interesting sessions came from the researchers at CSIRO in Australia who are working on a new indoor mobile mapping system that leverages SLAM - simultaneous location and mapping technology borrowed from the robotics world. This video will provide some insight. Indoor mapping is the next hot market - just ask Google. The ILMF 2012 proceedings will be available for free if you attended and for a nominal charge if you did not.
In summary, although the airborne LiDAR industry has been making significant advances over the past 15+ years much of the theoretical foundation remains to be established and more importantly put into practice as standard operating procedure. This would also apply to mobile LiDAR which has less of a track record, but similar theoretical issues. The issue of course is money, but it would seem that the various stakeholders would all benefit from a more coordinated, strategic approach.
One other note, given the overlap in membership I would hope that in the future that ILMF and MAPPS would work together to avoid scheduling their events for the same week. That really does not make sense.
The Spotlight in this issue goes to Bill Gutelius for his insights on the use of airborne LiDAR to map airport obstructions. The Video of the Week goes to Jody Lounsbury for his review of EdgeWise Plant 2.0.
With January closing our focus turns to 2 February events the Faro and Riegl user conferences - both new events in the show schedule. LiDAR News will be at both of these events working hard to keep you informed. We hope to see you there.
We are approaching 250 listings in the Resource Directory. Please take advantage of this opportunity to promote your firm to readers and organizations around the world: list your firm. And don't forget to send us your white papers and product videos as well. We want to help you to be noticed.
It is going to be an exciting year in many respects. Please let us know how LiDAR News can create more value for you, and encourage your colleagues to sign up for the newsletter here. We thank you for ongoing support in building this professional community.
Best regards,

LiDAR for Obstruction Mapping: Enabling Flight Safety
As laser scanning has evolved and matured, it has increasingly become a new and eventually necessary tool in many industries. One area that has benefitted from the application of laser scanning is aviation safety. Airborne LiDAR (Light Detection And Ranging) is used to detect and map obstacles that intrude into the airspace through which aircraft fly. Ground-based LiDAR (mobile and static scanning systems) technology has also been used recently ...

LiDAR Data Meets the MrSID Format

LizardTech® LiDAR Compressor™ software enables you to turn giant point cloud datasets into efficient MrSID® files that retain 100 percent of the raw data at just 25 percent or less of the original file size (lossless compression). If storage requirements are critical, you can reduce your LiDAR file sizes by 90 percent or more by choosing a higher compression ratio and letting LiDAR Compressor select the best way to reach a desired file size (lossy compression). Unlike raw LAS or ASCII data, LiDAR files compressed to MrSID are easily managed resources you can extract derivatives from again and again.
