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.

Kerry, Ireland. Filming and editing by Dr Max Kozachenko (Lecturer, Department of Geography and Coastal & Marine Research Centre, University College Cork, Ireland).
Laser Scanning Essentials
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 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...
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.

Shattuck St. Mary’s boarding school utilized laser scanning to revamp their outdated construction documents into 3D CAD format.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.
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.
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...
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.
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...
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.
Using the Leica Geosystems terrestrial laser scanner, we've been producing digital elevation models of cattle ramps. By comparing these models across time, we hope to quantify the mass loss caused by cattle.
