Camera Laser Scanner

Geo-knowledge for Preservation of St Maria Maggiore, Italy
Image-based modelling is still the most widely used approach in building documentation and 3D investigations, but panoramic camera laser scanners are gaining in importance. They offer large fields of view, good accuracy and direct photo-texturing. The authors have tested the information content and performance of such systems in 3D modelling of St Maria Maggiore, the ancient church in Bergamo, Italy. Technology is moving towards the development of an automated hybrid measurement system that may be called the "panoramic camera laser scanner", consisting of a Lidar device solidly integrated with a calibrated digital camera. Such new devices collect spatial point-clouds and,... (read more)

UAVs in the Mining Industry

Capturing the Andalusian Mina de Aguas Teñidas
A growing number of mining companies are employing unmanned aerial vehicles (UAVs). Equipped with digital cameras, such remote-controlled small aircraft generate high-resolution aerial imagery which can be further processed to produce highly precise orthophotos, point clouds and 3D models. Surveyors and engineers can use this data to make statements and forecasts about the development of the mine, document changes as well as calculate volumes of spoil and stockpiles. In mines with both aboveground and underground areas, UAVs can provide important information about the state of the aboveground area, thus improving the safety of the workers underground. This was practised in... (read more)

The Art of Monozukuri

Aichi prefecture in the centre of Japan is the home of Japanese ‘monozukuri’, in Japanese, ‘craftsmanship with inexhaustible enthusiasm and science’. It is also the place where major international players in the automobile, power-tools and chemical manufacturing industries have been founded. Here too, Myzox also came into being, founded upon and carrying with it all the tradition of ‘monozukuri’. The founder began the company in 1950, originally as a small woodworking plant. In 1954 a licence was obtained to manufacture measuring instruments by approval of the Japanese Ministry of International Trade and Industry, and the company started producing wooden staves,...

RADARSAT-2 To Be Launched in 2005

Features and Applications of Canada’s Second SAR Satellite
RADARSAT-2, Canada’s second Synthetic Aperture Radar (SAR) Earth observation satellite will offer users imaging flexibility and increased data information content, ensuring continuity of all existing RADARSAT-1 beam modes along with powerful new capabilities, from 3m resolution to flexibility in selection of polarisation. The satellite is due to be launched from Vandenberg Air Force Base in California in 2005. RADARSAT-2 is Canada’s next-generation commercial Earth observation Synthetic Aperture Radar (SAR) satellite, the follow-on to RADARSAT-1, launched in 1995. The new satellite has been designed with significant and powerful technical advancements and provides the fulcrum of a programme representing a unique partnership... (read more)

South Korean Smart Cities Combine 3D Digital Models with GIS and BIM

Around the world, local governments are rolling out Smart City/Digital Twin projects to support economic stimulation and tourism programmes and to improve the quality of life overall. Up-to-date 3D building models and comprehensive Geographic Information Systems (GIS) data, along with Building Information Modelling (BIM) data, are combined to create a digital twin of the inside and outside of buildings and the surrounding topography. In effect, the real world is converted into an exact digital replica to facilitate analysis, planning and management of all smart city assets. The primary goal behind 3D virtual cities is to reduce and manage problems typically... (read more)

An IFSAR Quality Management System

Meeting DEM and Ortho-imagery Specifications
Interferometric Synthetic Aperture Radar (IFSAR) is emerging as a highly cost-effective 3D mapping technology. Digital elevation models and ortho-rectified radar imagery are core commercial Intermap Technologies products using its airborne IFSAR based STAR technology, the list of applications for which is continually growing. Quality control and assurance ensure consistent data quality. Data quality has become a matter of escalating interest amongst the geospatial community. Data providers must thus ensure their data products meet specifications; quality must be built into the production process so that data consistently and predictably meets expectations. A rigorous Quality Management System (QMS) needs to be designed... (read more)

The Sky’s the Limit

In 1996 staff of what would become Southern Mapping Company, based in Johannesburg, South Africa, were among the first in the world to offer commercial aerial Lidar (light detection and ranging) survey. The service was quickly recognised by mining, infrastructure and environmental companies as providing the most accurate surface-terrain model information available. Today more than 50% of SMC activities are conducted on behalf of local and international mining clients.<P> Although SMC was founded only in January 2007, its team has been working with Lidar technology since the mid-1990s, when its founders gained experience in the technology from its conception.

Trimble Dimensions 2007

Welcome to the Third Dimension
Trimble Dimensions 2007 took place from 5th to 7th November 2007 at the Convention Center and Events Center, Mirage Hotel, Las Vegas, US. There were some 2,200 participants, up from last year's total of two thousand. With the usual format of plenary keynote sessions, technical sessions and a trade show, the event sported the theme “Transform Your Business with the Connected Site”.<P> Trimble president and CEO Steve Berglund kicked off the conference, saying 'Welcome to the third dimensions'. His phraseology was intentional; the conference would focus on three dimensions, paralleling developments in the geospatial world. Pointing out how far technology... (read more)

Development of the ILRIS-36D

Balancing User, Market and Design Objectives
The ILRIS-3D laser scanner was launched in 1999 as a measuring system for 3D-point cloud collection. In October 2004 Optech launched its second-generation, tripod-mounted laser scanner, the ILRIS-36D. But getting the new design to meet the sometimes conflicting objectives of end user, laser scanning market and internal design team proved a challenge. The author offers insight into design decisions and driving factors for developing the scanner. The design of the new ILRIS laser scanner began with three questions. How to provide a scanner that makes good business sense for its owner? How to improve the scanner technically while maintaining focus... (read more)

GRACE Follow-up Mission to Keep Close Eye on Ice Loss

A few months ago, the GRACE mission’s two Earth observation satellites burnt up in the atmosphere. Although this loss was planned, for the experts at the Alfred Wegener Institute it left a considerable gap in monitoring ice loss in the Antarctic and Greenland. Now the follow-up mission will finally be launched, and will play a vital role in predicting future sea level rise. One of the greatest threats in connection with climate change is the continuing rise in sea level – and the more intensively the enormous ice sheets in Greenland and the Antarctic melt, the worse it will become....
