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.

3D Educational Event on the Battleship New Jersey

nj scanOn September 10, 2014, Leica Geosystems, in conjunction with the Surveyors Association of West Jersey, will host a special half-day educational event for transportation surveying and engineering professionals on the nation’s largest battleship, the Battleship New Jersey, anchored in Camden, N.J. For more information or to register, visit http://novalearningnetwork. com/battleship-nj-seminar/.

As part of this effort Leica Geosystems and Haag 3D are also scanning the New Jersey as a volunteer effort. “Our firm is dedicated to reaching out and providing our technology and experience to the community we live in,” said Christopher Zmijewski, vice president of Haag 3D Solutions. “Having the Battleship New Jersey in our backyard provides a unique opportunity to completely scan the ship. We recognize how HDS documentation technology can be used to enhance future visitor and educational experiences, while documenting the ship as the engineering marvel she is.”

The ROI for 3DEP

LidarIn this well written article from Information Week the author provides eight examples of the way in which 3DEP (USGS 3D Elevation Program) data can be used to improve geographic decision making. The goal of 3DEP is to systematically collect enhanced elevation data using lidar over an eight-year period. Alaska is one exception, where interferometric synthetic aperture radar (ifsar) will be used to collect data, since cloud cover and remote locations prevent the use of lidar.

3DEP is based on the results of the National Enhanced Elevation Assessment, which found more than 600 business and science uses for 3D mapping data across federal agencies, all 50 US states, local government and tribal offices, nonprofit organizations, and the private sector. The program design was determined from analyzing the uses in the study and selecting the best return on investment. Based on the assessment, 3DEP will meet $690 million of the documented benefits annually if it is fully funded, Lukas said.

Mobile Lidar Improves Rail Safety in France

3DLM_Fit_ESIC_Rail_0406FIT ESIC used a rail mounted StreetMapper to survey several hundreds of kilometres of track, generating engineering grade survey data on behalf of SNCF. The laser generated computer model was used to build a detailed 3D topographic map of the tracks and its surroundings.  This provided length data and cross profiles as well as detecting potentially dangerous objects near the track.

Bruno Landes, Head of the Works Assistance and Surveying Division at SNCF (Societe Nationale des Chemins de Fer Francais) France’s national state-owned railway company, added: “LiDAR technology  has without a doubt improved the management of our railway infrastructure. The data has been used as topographic inputs for railway modernisation studies, gauge studies and electrification studies, for example.”
