Lidar

This issue of GIM is largely devoted to emergent Lidar technology. We have a feature on 3D-visualisation of Lidar data co-authored by new contributing editor Dr Bharat Lohani of IIT Kanpur India, and no fewer than two product surveys, one on Airborne Lidar Systems, the other on Lidar software. Two regular features, Technology in Focus and Company’s View, this month address processing the product of Lidar survey, point-clouds. Lidar is without doubt a most successful data-acquisition technique. As an acronym of Light Detection and Ranging - some prefer to read Lidar as Laser Imaging Detection And Ranging - the term...

LiDAR Compressor

LizardTech has released the LizardTech LiDAR Compressor. This product enables users to turn giant point cloud data into efficient MrSID files that retain 100% of the raw data at just 25% of the file size.     Unlike raw LAS or ASCII data, LiDAR files compressed to MrSID are easily managed resources from which derivatives can be extracted over and over again. One of the key features of LiDAR Compressor is its ability to reduce LiDAR file sizes by 75% while retaining all of the points and all of the point precision and accuracy of the original file. If users... (read more)

European Lidar Mapping Forum

The ELMF team are taking the show to Salzburg, Austria from 29th to 30th November 2011. In four weeks time, since the launch of the second event, old and new exhibitors are taking stands with 60% of the floor plan already allocated. The organisers are also enjoying a very positive response to the Call for Papers that was announced recently with many abstracts already submitted. The deadline for online submission is 25th July 2011. The ELMF conference is a platform on which to launch the latest concepts from commercial or academic research, leading-edge innovations in technologies, improved operating practices, reports...

Mapping with Mobile Lidar

High Speed, Accuracy and Density
The use of Mobile Lidar systems enters the scene when large areas have to be surveyed at accuracy and resolution exceeding those available through aerial photogrammetry, and when using static Lidar is impractical. The Lynx Mobile Mapper captures high-accuracy, high-density points, allowing easy and precise identification of objects. In 2006 Sineco S.p.A, an Italian engineering firm belonging to the ASTM Group, began collaborating with Optech Incorporated, the Canadian manufacturer of laser-based imaging systems, to develop a mobile Lidar system. The first prototype, ready in early 2007, combined two ILRIS-3D laser scanners with a position-and-orientation system (Applanix POS LV 420). This... (read more)

International LIDAR Mapping Forum

ILMF
International LiDAR Mapping Forum (ILMF) is a technical conference and exhibition showcasing the latest airborne, terrestrial, and underwater LiDAR as well as emerging remote-sensing and data collection tools and technologies. With a special emphasis on data acquisition, fusion, integration, processing and visualization, ILMF is the must-attend event for professionals involved in utility asset management, transportation, urban modeling, coastal zone mapping, and more. At the 2017 event, you will: Learn the difference between Geiger-Mode LiDAR (GML) and Single-Photon LiDAR (SPL) and why it matters Hear about GML/SPL applied to large scale projects Go in-depth on point clouds: From processing and feature extraction to analysis and management...

Velodyne Live Lidar Demos

Velodyne Lidar (USA) is displaying its latest in sensor technology, the HDL-32E, on Stand 39 at the 2011 SPAR international conference being held this week at the Waterway Marriott Hotel and Convention Center in Houston (TX, USA). Visitors to the show can see the HDL-32E in action at the Mobile Scanning and Mapping Demo being held in the circular driveway of the convention centre.   The HDL-32E is a small, lightweight and rugged sensor designed to meet the demand for 3D mapping applications and autonomous navigation. It features 32 lasers across a 40° vertical Field of View (FOV) and generates... (read more)

First ALS LIDAR Project

Airborne Laser Solutions (South Africa) has undertaken the first aerial lidar survey project in its new Rockwell Aero Commander 1000 aircraft. This survey is required for the route selection and design of a 220km-power line linking Tete in Mozambique and Blantyre in Malawi. The company’s prime equipment currently consists of an Optech 3033 ALTM LiDAR system combined with a Hasselblad camera and Phase One digital back. With this equipment in the Aero Commander ALS is able to generate terrain models at 50cm to 10cm vertical accuracy, and colour digital orthophotos at pixel ground resolution ranging from 50cm to 10cm. The... (read more)

Lidar Rectification Software

Optech has released the Optech LMS Lidar Mapping Suite for its Lynx Mobile Mapper clients. It offers Lynx clients a new workflow designed specifically for high-volume production processing, and incorporates a fully automated batch-mode capability.     Optech LMS enables simultaneous processing of multi-mission data collects, and includes multi-threaded and distributed processing capabilities to further increase processing efficiency.   According to Daina Morgan, Optech's Lynx Mobile Mapper product manager, Optech LMS Standard includes all the capabilities the clients are used to, with the added feature of comprehensive coordinate conversion. This facilitates a transition without the need of extensive retraining.   (read more)

Lidar Forum Dates Set

Following on from the previous success of both the European Lidar Mapping Forum and the International Lidar Mapping Forum, the organisers have now set the dates for the next edition of both events. ELMF will be returning to Salzburg, Austria, from 4th to 5th December 2012, and ILMF will be returning to Denver, Colorado in the US from 11th to 13th February 2013. In 2011, when ELMF moved to Salzburg from The Hague in The Netherlands, the venue received so much positive feedback from visitors and exhibitors alike that the organisers are planning to return there for a second year....
