The US Army has developed a long distance LiDAR system allowing them to better calculate range and velocity measurements of long distance targets, such as incoming missiles. This technology allows them to more accurately discern between actual threats and false alarms. At closer ranges, they will be able to create 3D images in near real-time of these threats. If you are interested in becoming a partner and applying for a license for this technology, or if you are interested in more details regarding this technologies capabilities and technicalities, please click here.

Dr. Damian Evans, an Australian archaeologist, is the architect of the Cambodian Archaeological Lidar Initiative (Cali) and a research fellow at Siem Reap’s École Française d’Extrême-Orient (EFEO).
In 2012 and 2015 The Cambodian Archaeological Lidar Initiative scanned the jungles of Cambodia, finding new and groundbreaking evidence of medieval cities that once stood there.
The ERC, European Reseach Council funded the 2015 scan project based on the work Evans did in 2012 which unearthed the network of medieval temple-cities. At that time, a city was found beneath Mount Kulen, proving what archeologists has been suspecting for some time.
The much larger scan conducted in 2015 showed the immense scale of the city beneath Mt. Kulen including features such as elaborate water systems. In June, the Guardian reported that these findings could “upend key assumptions about south-east Asia’s history”. Evans says these discoveries even “call into question the whole notion of an Angkorian collapse.”
The research from these scans by Dr Damian Evans have been published in the Journal of Archaeological Science.
The team at Lidar News is very interested in continuing to follow the incredible work that the Cambodian Archeological Initiative is doing. We will share their findings here and in more detail at the Lidar News website.
Most of the news on autonomous vehicles centers around the world of vehicles designed for roads. But what if your city or town is surrounded by water – what if the avenue to your home or business is not a road, but a canal?
With global technological movement flowing towards self driving vehicles, it was only a matter of time before a metropolis such as Amsterdam started thinking about the future of autonomous vehicles in terms of their city landscape. And that means boats.
Enter the Massachusetts Institute of Technology. They are pairing up with the Amsterdam Institute for Advanced Metropolitan Solutions (AMS Institute) to begin the world’s first large scale research project on autonomous floating vessels for cities, cleverly called Roboat. This is a five year initiative including researchers from MIT, Delft University of Technology and Wageningen University and Research.
The budget? 25 million euros. The first prototypes? AMS says they’ll be in the water in 2017.
I think it’s safe to say we’ll be seeing much more news about this project and any others of its scale focusing on autonomous vehicles.
What’s next? Autonomous ice cream trucks? I’ll have mint chocolate chip, please.
Read more on the project at AMS.

Leica Geosystems has announced the launch of HDS University, a new hands-on educational opportunity for professionals looking to expand their skillset in the growing field of laser scanning/high-definition surveying (HDS). During a three-day session Oct. 25 through 27, HDS University will bring courses in laser scanning hardware and software to professionals at the Leica Geosystems Americas region headquarters near Atlanta.
A quick review of the listing shows a wide variety of topics and areas of interest. The cost is $395 per course.
In partnership with the University of Arkansas, Leica Geosystems is offering continuing education unit (CEU) credits on most HDS University classes. A limited number of one-on-one consulting sessions with Leica HDS experts are also available on Oct. 24 and 28 for a nominal additional fee.
An early registration discount of 20% is available to those who sign up for their courses by September 30.
It seems that the promise of full waveform technology has not yet been realized. This team of researchers at the University of Heidelberg in Germany note that for the forestry application at least “an extensive overview, categorization and comparison of features from full-waveform airborne laser scanning and how they relate to specific tree species are still missing.”
To address this they provide a review that “identifies frequently used full-waveform airborne laser scanning-based point cloud and waveform features for tree species classification and compare the applied features and their characteristics for specific tree species detection. Limiting and influencing factors on feature characteristics and tree classification are discussed with respect to vegetation structure, data acquisition and processing.”
Have you used full waveform?
This is an excellent article on the background of the relationship between Uber and Carnegie Mellon University’s robotics lab, NREC. The original plan was for Uber and CMU to form a partnership to work on autonomous vehicles. Instead Uber hired 40 of the lab’s 100 scientists, as well as the director. They set up an office about a mile from NREC.
Interesting as that may be, the issue that I wanted to focus on is the following response from Herman Herman, the Lab Director when asked about the status of autonomous vehicle research, “With autonomous cars, you see these videos from Google and Uber showing a car driving around, but people have not taken it past 80 percent. It’s one of those problems where it’s easy to get to the first 80 percent, but it’s incredibly difficult to solve the last 20 percent. If you have a good GPS, nicely marked roads like in California, and nice weather without snow or rain, it’s actually not that hard. But guess what? To solve the real problem, for you or me to buy a car that can drive autonomously from point A to point B—it’s not even close. There are fundamental problems that need to be solved.”
I guess you could say it is the old 80/20 rule, perhaps in reverse.

Scanse recently announced that they have completed a pilot run of their low cost, 2D Sweep lidar sensor, finalized the mechanical dimensions and production is now underway. With a range of 40 meters and the ability to operate outdoors, not to mention the $250 price tag it is going to be interesting to see what the professional community does with this disruptive technology.
One of the co-founders explains the innovation behind the Sweep –
“Sweep is based on a new time of flight ranging method, which involves sending out laser pulses that are made up of a series of micro pulses. These micro pulses act as a kind of light based checksum, which allows the sensor to more easily correlate returning light to the known pattern, and achieve a phase difference measurement. This method is much different than traditional LIDAR, which uses a train of identical pulses to measure the phase difference between outgoing and incoming light.
The traditional method requires the pulses to be much brighter than ambient light, otherwise it gets drowned in noise. This requires high power lasers and finely tuned detectors. The new method we are using allows the sensor to use lower power components, which contributes to its low cost. This also gives it the ability to sense surfaces up to 40 meters away, even in noisy sunlit environments. A final added benefit comes from the fact that each pulse packet is unique, which means the sensor can reject multi-bounce returns (as they would come out of order), as well as light from adjacent sensors.”
NOAA’s Office of Coastal Management Digital Coast is offering a free, online training course entitled, “Introduction to Lidar.” It’s an 80 minute tutorial including the following topics:
- Define lidar
- Select types of elevation data for specific coastal applications
- Describe how lidar data are collected
- Identify the characteristics of lidar data
- Distinguish between lidar data products
- Recognize aspects of data quality that impact data usability
- Locate lidar data sources and additional information resources
This self-paced, online training introduces several fundamental concepts of lidar and demonstrates how high-accuracy lidar-derived elevation data support natural resource and emergency management applications in the coastal zone. The material provides geospatial analysts with the information needed to understand the characteristics of lidar that have direct impacts on mapping and spatial analysis projects. A demonstration is included to show how lidar data can be downloaded from NOAA’s Digital Coast.
