On 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.”
In 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.
FIT 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.”
This is an excellent article on the right way to think about building information modeling – BIM. To get the maximum value out of BIM it needs to be introduced at the start of a project and continue throughout the lifecycle of an asset.
“When we say building, we refer to it as a continuous verb rather than a physical asset,” explained Nader Reslan, Manager for the Rail Sector, Bentley Systems. “BIM embraces the entire lifecycle of the building process beyond the initial design phase to include build, operations and maintenance phases.”
Reslan pointed out that BIM is not a product, data format or vendor-specific initiative. Nor should it be confused with a massive 3D CAD model, GIS model or a hybrid of both.
In July of 2011, architects from the U.S. National Park Service’s Historic American Building Survey (HABS) embarked on a ground-breaking project to fully document the Ghazni towers. Using high definition surveying, also known as laser scanning, Dana Lockett and Paul Davidson captured the elaborate terracotta details of each façade as well as the brickwork of their exposed foundations to a level of accuracy never previously achieved. Their work, sponsored by the U.S. Department of State’s Cultural Heritage Center, is an effort to help cultural heritage professionals in Afghanistan preserve the towers by providing baseline documentation that will underpin future conservation and preservation activities.
The architectural detail of the towers is amazing.
Autodesk is promoting what they call “reality computing” as the integration of 3D laser scanning, 3D modeling, 3D printing and augmented reality. According to Rick Rundell, Technology and Innovation Strategist at Autodesk, we are only at the beginning of a long arc of change in the way we interact with physical and digital data, and in the way we experience reality itself.
We’ve been using the term digital transformation, but it’s the same concept. It’s an interesting read.
Now this is a great idea. Thanks to Wolfgang Juchmann at Velodyne for the heads up.
A hardware and software technology company, Essess provides drive-by thermal imaging capabilities that enable utility and government clients to identify energy waste in buildings on an unprecedented scale. While Essess drives on public roads, it uses thermal cameras combined with real-time LiDAR sensors (Velodyne HDL-32E) to capture 3D thermal video of the surrounding environment.
The imaging system consists of a custom-designed multi-sensor rig integrated onto the top of the vehicle. As the vehicle drives, the thermal cameras measure the heat signature of the buildings, and the LiDAR imaging rig captures the structures in 3D on both sides of the car, enabling Essess to image large geographic areas each night. The images are stored onboard the vehicle using a custom-built data recording system and then processed at Essess headquarters in Boston.
This should be a major winner.
