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...
3D Laser Scanning ( Combination of Lidar and Terrestrial laser Scanning Data)
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).
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.
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.
Terrestrial LiDAR scan of a courtyard with true color point cloud colorization. This point cloud was made to be used in Revit to create a 3-D architects model for design purposes. Scan performed by Civil Design & Engineering Inc., with locations in Flagstaff, Phoenix, and Tucson, AZ.
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.
Exact Metrology offers several options for long range scanning. The Leica long range scanners are eye-safe laser scanners that incorporate two different scanning technologies: time-of-flight and phase based. Each technology is unique in its ability, range, speed and accuracy. The Leica time of flight scanners send a pulse laser using mirrors 270 degrees vertically and 360 degrees horizontally to record the environment. The emitted laser bounces off an object and returns a signal to the device. The measured "time" the laser has left and returned is used to calculate the distance of the object. The latest versions of Leica's time-of-flight systems can capture as many as 50,000 points per second. This scanner will capture data up to 100 meters (300 feet) with the accuracy of typicall...
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.

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.
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, ...

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...
