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.
Shafer Kline & Warren’s Light Detection and Ranging (LiDAR) scanning provides comprehensive, high-definition survey information with unsurpassed accuracy and efficiency. SKW’s LiDAR gurus Scott Confer and Patrick Crawford provide insight into LiDAR scanning, and how they leverage the technology to engineer solutions for energy and infrastructure. Many structures lack accurate as-built documentation or site data, and without this information, companies are unable to assess their current structures or perform facility modifications and updates. With scan speeds of up to one million points per second, LiDAR technology reduces the time needed to collect survey data and produce actionable data, which allows companies to complete projects sooner and meet tight deadlines. Additionally, LiDAR scan...
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).
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.

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.
In the webinar we will demonstrate the simulation of different laser scanning setups and the analysis of speckle pattern for scanned images. * Simulation of laser scanning systems based on setups exhibiting one and two scanning mirrors with different subsequent lens configurations. * Analysis of beam deformations caused by static and dynamic aberrations of the scanning mirror. * Investigation of speckle pattern in laser scanned images observed by the human eye.
Terrestrial scanning is a useful surveying tool that can help to accelerate natural gas development.

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
RIEGL VZ-400/ VZ-1000 in three application examples: Scanning of the Millennium Tower and St. Peter's Church, both in Vienna Austria, and in Forestry Assessment. The V-Line 3D Terrestrial Laser Scanners RIEGL VZ-400/ VZ-1000 provide high speed, non-contact data acquisition for ranges up to 600m/ 1400 m using a narrow infrared laser beam and a fast scanning mechanism. High-accuracy laser ranging is based upon RIEGL's unique echo digitization and online waveform processing, which allows achieving superior measurement capability even under adverse atmospheric conditions and the evaluation of multiple target echoes.
3D Laser Scanning ( Combination of Lidar and Terrestrial laser Scanning Data)
This video clip has been generated from Terrestrial Laser Scanning data of some 150 - 200 year old trees (Abies Alba and Picea Abies) growing in a traditionally manged and privately owned "Plenterwald" forest in the Black Forest Mountain Range in Southwest Germany. Such a "Plenterwald" is an old sylvicultural forest management system based on individual tree selection. It is very close to nature and typical for privately owned farm forests in the Black Forest. Other Plenterwald forests are growing in Switzerland and Austria. The biggest tree, a White Fir (Abies Alba), is 45 m high and its stem has a diameter at breast height of 1.32 m (perimeter: 4.15 m), the estimated tree volume is about 25 cubic meters. With 6 Laserscans from different positions all data visible in the video clip w...
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...
In this video we will share with you some technology that can have a significant impact on your cases, terrestrial laser scanning. Laser scanning is simply a process which accurately measures 3 dimensional objects or scenes. Think of it as a 3D photo. There are many types of laser scanning: satellite, airborne, bathymetry, mobile and terrestrial. This video will focus on terrestrial laser scanning.
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, ...
Advin developed its own innovative scanning vehicle. It is unique in the world. No other system is as accurate or reliable as Advin's system. Dynamic scanning makes it possible to measure roads, railways, dikes, canals, buildings and even complete neighbourhoods with high accuracy at speeds up to 120 km/h.
