Celebrating Labor Day

Here in the U.S. we are celebrating Labor Day. I used to always joke with my employees that this meant you were supposed to be working on Labor Day, but the truth of it is “Labor Day, the first Monday in September, is a creation of the labor movement and is dedicated to the social and economic achievements of American workers. It constitutes a yearly national tribute to the contributions workers have made to the strength, prosperity, and well-being of our country.”

Well said and thank you to everyone around the world for all of the hard work you put in to your careers and for your employers.

Lidar and Rowing

I was rowing on the Exeter River the other day when I heard a helicopter approaching. It was flying low and slow. I realized it was collecting lidar on the powerline ROW that is close to our boathouse. My two passions linked together – what a coincidence.

50 Years of 3D

In case you have been thinking that the use of 3D is a relatively new phenomena have a look at Ralph Grabowski’s latest upFront.eZine post on the history of 3D CAD at Dassault Systems. Turns out Dassault has been promoting the advantages of 3D for nearly 50 years – incredible.

The aircraft and automotive industries have been reaping the benefits of 3D for decades, but for some reason the AEC world is still hesitant to change. Construction is different from manufacturing, but there is still tremendous opportunity to “build the model.”

Digitally Documenting the Lincoln Memorial

As a follow-up to a post last December the scanning of the Lincoln Memorial has been completed by DJS Associates.

On behalf of the National Park Service (NPS) and CyArk, a non-profit organization, DJS donated its time and resources to gather millions of data points in order to capture accurate, reliable measurements of the monument, both interior and exterior.  The highly accurate record of the three-dimensional measurements and panoramic high-dynamic range photographs will be extremely useful in site management, as well as providing the ability for visitors from all over the world to explore the Lincoln Memorial virtually.

Look for a detailed article on this project in an upcoming LiDAR News Magazine article.

Laser Scanner Provides Quality Control for 3D Printing

Suppose your 3D printer malfunctions in the middle of a project. After you get it fixed how do you know where to restart the print job? A couple of M.I.T. students claim, as reported in Tech Page One, that they have the problem solved at a cost of less than $100.You simply scan what has been printed and compare it with the model to know where you should restart.

It has a bit of a science fair project feel to it, but I think they do have a good idea. What do you think?

Using Lidar to Improve Earth’s Climate

A Motherboard  article reports that two separate scientists put forward proposals to use lasers to modify the Earth’s climate and fight global warming, from space.

One suggested that a satellite equipped with a high-powered laser could grow clouds in the atmosphere below; the other proposed lasers that would blast greenhouse gases from orbit to effectively erase the agents of climate change.

And European Space Agency fellow Isabelle Dicaire studies them full time. She traveled to Berlin this week to discuss how a satellite equipped with high-powered LIDAR lasers may prove useful for researching—and maybe eventually actually orchestrating—climate engineering.

It’s still in the early stages of theoretical discussions, but one can dream.

ASPRS Establishes UAS Test Course

The ASPRS (American Society of Photogrammetry and Remote Sensing)  has announced that they have established the first UAS mapping calibration test course. The course will be established at the Reno Stead airport, an FAA-designated UAS test site.

The course will include ground surveyed targets of varying height, radiometric targets, undulating surfaces, “surprise” targets, and simulated flight restricted areas.  The first UAS flights of the test course will be conducted in conjunction with the UAS MAPPING 2014 RENO symposium on October 21-22, 2014 in Reno, Nevada.

Laser Scan From Multirotor Platform

sabreThis may be one of the first scans from a from a multicopters drone. All up weight less than 20kgs. It looks like the a glacier but it is a quarry.
