This initiative is introduction of 3D Terrestrial Laser Scanner System for accurate and human intervention free measurement of the coal and Over Burden face in all major mines which is helping in accurate determination of volume of coal and OB extracted from the mines.
Sarah Kandrot (Phd Researcher, Department of Geography, University College Cork, Ireland) is talking about her research using Terrestrial Laser Scanner for monitoring changes in the morphology of sand dunes at Rossbeigh, Co. Kerry, Ireland. Filming and editing by Dr Max Kozachenko (Lecturer, Department of Geography and Coastal & Marine Research Centre, University College Cork, Ireland).
Shattuck St. Mary’s boarding school utilized laser scanning to revamp their outdated construction documents into 3D CAD format. The project was an excellent example of the value of terrestrial scanning. Using highly accurate 3D scan data generated with 3D scanning you are able to view as-built documentation in a virtual world. The point cloud data can also be surfaced to generate a CAD model which can be used for comparison or reconstruction.

To showcase the outstanding qualities of the RIEGL VZ-400i for underground data acquisition of large areas, a special 3D laser scanning project was executed in summer 2017. Data of the famous Eisriesenwelt, a cave labyrinth with a total length of more than 40 kilometers in Werfen, Austria, was captured in 370 scan positions within two days. Only four hours were necessary for registration and post processing of the data. Based on RIEGL’s Waveform-LiDAR technology, additional scan data attributes are provided with each measurement. Using the reflectance value - for example - allows surface material detection and e.g. visualization of all surfaces covered with ice.
The necessity for monitoring geo-risk areas such as rock slides is growing due to the increasing probability of such events caused by environmental change. Europe is one leader in survey technology, due to well-established providers of measurement systems and frameworks. In Europe, rock slides cause increasing damage particularly in alpine areas. DE-MONTES provides an efficient, highly automated, high-resolution, terrestrial, long range sensing measurement and analysis system which is able to monitor geo-risk (and related) objects by means of non-signalized natural target points -- which is a key to such systems due to the lack of reachability and the required distance-to-the-object. Even novel sensor concepts such as terrestrial laser scanning can only cover a subset of the requirements, ...
Darling's 3D Laser Scanning services have revolutionized the way mining industries map underground assets. With an accurate 3D model of existing drifts and shafts, you can take the guesswork out of where and what to develop. Match our 3D model with your ore body mapping to get a complete picture of what is happening underground. All this can be done without costly downtime in your mining operation in most cases.
3D Laser Scanning ( Combination of Lidar and Terrestrial laser Scanning Data)
A short course last August at the Indiana University Judson Mead Geologic Field Station in Montana brought together 21 geoscience field instructors to learn about incorporating terrestrial laser scanning (TLS; sometimes called ground-based lidar) and structure from motion (SfM) photogrammetry into geoscience courses with field components. Both methods can be used to generate high-resolution, three-dimensional topographic models that can be applied to hazard assessment, geomorphic change detection, and stratigraphic sequence analysis, to cite a few examples. In this scene, meeting attendees were scanned from a single position by a Riegl VZ-1000 scanner. The entire scan took a few 10s of seconds and the laser was only on a given participant for seconds. The final scan resolution was less th...
Watercourse crossing scanned with Terrestrial LiDAR
Well, here's a complete how-to if you want to do this yourself in your area - just please be sure you are legal, there are a lot of restrictions in many areas. And I show you why I'm done with it FAR earlier than I wanted to be obviously.
Land forming is the process of applying a man-made slope on land to be used for irrigation. The I-Site laser scanning system brings accuracy and efficiency to the process to ensure the correct grade for pre-determined watering and drainage systems.
Trunking can be better thought of as computer controlled radio. In this video we explore the origins, mechanics and benefits of using a Trunked network. Dr. Jan Noordhof is an independent principal consultant with over 20 years experience in radio standard development, software engineering, systems programming, telecommunications, embedded system design, and teaching at a number of universities. Tait Radio Academy is a free online resource for all things radio. You can find more at www.taitradioacademy.com.
Engineering geologist, Pete Hobbs, explains how the British Geological Survey landslides team use Terrestrial Light Detection and Ranging (LiDAR). LiDAR is a land-based laser scanner which, combined with a highly accurate differential GPS and camera, enables us to produce 3D computer models of landslides in coastal areas.
This 3D VZ-Line Laser Scanner offers superior and unrivalled long range measurement performance of up to 4000 m reflectorlessly while still maintaining completely eye safe operation (Laser Class 1). RIEGL's unique V-Line technology is based on echo digitization and online waveform processing and is the key to enabling such extreme long range measurements. The VZ-4000 operates even in poor visibility and demanding multi target situations caused by dust, haze, rain, snow, etc. which are frequently found in difficult environments such as mine sites.More Information: www.riegl.com
