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 following diagrammatic animation outlines the differences between traditional field measuring practices vs. terrestrial laser scanning. In addition, it shows the Enhanced Analysis Capabilities, and advantages allowed by laser scanning, and the collection of point cloud 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).
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.
Terrestrial scanning usually generate redundant points. VRMesh allows you to remove redundant points that can speed up the whole process of classifying points and creating accurate ground surface.
Shattuck St. Mary’s boarding school utilized laser scanning to revamp their outdated construction documents into 3D CAD format.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.

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.
In November KCI purchased a RIEGL VZ-400 3D Terrestrial Laser Scanner. This portable surveying instrument can collect millions of data points within a 400 meter range in a matter of minutes. The scanner emits a light pulse outward towards a target surface and measures how long it takes for the beam to hit and return while spinning in a 360 degree pattern. The system calculates the beams horizontal and vertical angles and captures anywhere from 5 million to 45 million data points into a database called a point cloud. From each scan position a digital camera captures images which are used to color the scan points. The point cloud is then recorded into a 3D visualization program, and matched with the digital images to create a panoramic view. By taking multiple scans and using target traver...
Our target-based registration is a manufacturer-independent solution for registration of terrestrial laser scanner data. Thanks to the carefully thought-out operation as well as quick and reliable finding and assignment of checkerboard targets and reference spheres, even non-experts can use a tool that allows reliable registration of terrestrial laser scanning data. If you work in smaller projects without targets or if a target is missing once, you can still register as easily due to natural corresponding points.
This professionally produced HD video illustrates how laser scanners work and describes which scanner features are important to consider, the topic of "registration" or stitching multiple scans together, and what type of support is available for implementing the technology. Highlights of key Leica Geosystems' scanner features are described and a high-level overview of software is given.

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.
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...
