Time-space Modelling with Terrestrial Lidar

Monitoring Ice Cliff Evolution of the Miage Glacier, Italy, with ILRIS-3D
The Miage Glacier at Mont Blanc Massif, with an area totalling 11km2, is the third largest glacier in Italy. Time-space modelling of the lakebed and glacier walls carried out with terrestrial Lidar revealed that the ice cliff had retreated more than 45m between July 2003 and September 2004. The Miage Lake area, which has been a tourist attraction and object of study for decades, has been affected by at least seventeen drainage events over the past hundred years, the most recent just last year. Observations during this last event suggest that an increased discharge of water from the lake, resulting... (read more)

3D Modelling of Shukhov Tower

Using Laser Scanning to Model a Russian Radio Tower
The 90-year-old Shukhov Tower in Moscow, Russia, is not only in a state of severe disrepair but the 150m-high steel construction is also under-documented. To support restoration initiatives or, in case of unexpected collapse, to enable the tower to be observed virtually, the authors carried out ground-based laser scanning using seven scan positions to create a detailed 3D model. Built in the period from 1919 to 1922, the radio tower at Shabolovka is an icon of Soviet broadcasting and a world-renowned monument of Russian avant-garde architecture. Today it is called Shukhov Tower after its designer V.G. Shukhov (1853-1939), an outstanding... (read more)

Air Pollution Modelling with 3D Visualisation

UK-based environmental engineering company Cambridge Environmental Research Consultants (CERC) has been using the TatukGIS Developer Kernel (DK) ActiveX edition since 2007 to develop the GIS mapping module for its ADMS air pollution modelling software. The mapping module developed from the TatukGIS DK, called ADMS Mapper, is used to visualise and edit input data for the ADMS modelling software. The Mapper can render pollutant concentrations output from the ADMS model. Before ADMS Mapper became available, users of ADMS had to buy third-party GIS software such as ESRI ArcGIS or MapInfo to visualise their modelling scenarios. ADMS is used by hundreds of people...

3D Modelling from RGB Images

FOVEX Measure 3D is a combination of a super-fast high-resolution 360° panorama camera and innovative software that allows accurate measurement and CAD modelling directly within the images. FOVEX Measure 3D allows significant savings in field and office work, thereby increasing productivity. The technique is to be presented at Intergeo, taking place from 9 to 11 October 2012 in Hanover, Germany. After measuring an object in two images, its shape can be modelled by connecting points directly in the software. Therefore, the CAD model can be completed within the FOVEX software directly and the model as a whole can be exported... (read more)

Maptek Demonstrates Resource Modelling Technology at PDAC

With the investment stream opening up, visitors to this year’s PDAC in Toronto, Canada, will be keen to explore resource estimation and project evaluation tools that can add value to mining projects. Maptek adds value to the entire mine cycle, from exploration through modelling, mine design, optimisation, production and rehabilitation. Maptek capabilities for handling large datasets are developed to make targeting easier. Evaluating multiple prospects on the desktop helps ensure money is not wasted pursuing an uneconomic project. The data remain available and processes are fully auditable and can be revisited when conditions change. Maptek’s latest Eureka 3 allows multi-source,... (read more)

Sharing and Reusing Geospatial and Modelling Data

Last month, Envitia, UK, announced the launch of Envitia Discovery 2.7 for modelling and simulation. Envitia Discovery allows organisations to seamlessly share and reuse geospatial and modelling data. Users are able to rapidly discover, transform and stream geospatial data into modelling and simulation applications using open standards. Powerful production workflows coupled with an intuitive web portal ensure that end users are never more than a few clicks from finding their required datasets. Envitia Discovery reduces the time spent hunting for data and instead allows more time for data visualisation and exploitation in systems. Envitia Discovery 2.7 bridges the gap between live...

Modelling the Great Wall of China

Mapping by Airborne and Terrestrial Lidar
The Great Wall of China is one of the largest manmade wonders of the world, comprising many different and irregular structures. We employed airborne Lidar to produce highly accurate digital elevation models (DEMs) to identify areas requiring repair. A terrestrial laser scanner mounted on a tripod was used to improve the terrain model, especially for surfaces covered with dense vegetation. The combined use of airborne and terrestrial laser scanner produced DEMs with accuracies better than 10cm. The easternmost end of the Great Wall, Shanhaiguan Great Wall, is in the city of Qinhuangdao in Hebei. Although the wall is intact, the... (read more)

Free Modelling and Simulation Terrain Databases

The U.S. Army Geospatial Center (AGC) is distributing Modelling and Simulation (M&S) terrain databases along with operational geospatial products on its Common Map Background (CMB) website with the goal of providing a single repository for all geospatial products. There are 161 free synthetic terrain databases that support Live, Virtual, & Constructive (L/V/C) simulations used in training, testing and experimentation hosted on CMB. These M&S terrain databases are available in multiple formats suitable for use in Joint Semi-Automated Forces (JSAF), One Semi-Automated Forces (OneSAF), Virtual Battle Space 2 (VBS2) and other Department of Defense simulations. Available terrain databases include selected Army... (read more)

Capturing, Modelling and Building the Reality

Interview with Aidan Mercer, Bentley Systems
Bentley Systems held its latest annual Year in Infrastructure Conference in London, UK. The event proved to be an excellent opportunity to take a look behind the scenes at Bentley, a leading provider of software solutions for advancing infrastructure. 'GIM International' talked with Aidan Mercer, global industry marketing director for utilities and government. In this in-depth discussion, he zooms in on the role the company plays in advancing the world’s infrastructure and how geomatics is a key element of many of Bentley’s applications. (By Wim van Wegen, content manager, GIM International) We’re hearing a lot about reality modelling at Bentley’s Year... (read more)
