Modelling Prague Castle with a UAS

Capturing a Highly Secured Site from the Air
In a recent project to obtain detailed and accurate orthoimages and 3D models to support technical staff in maintaining Prague Castle in the Czech Republic, the site was captured by UAS photogrammetry. Videos and georeferenced panoramic images were also taken as a service to documentalists and to provide the basis for virtual tours for tourists. Prague Castle and its surroundings are heavily secured sites and special permission was required to conduct the air survey. Learn more about this unique project here. By Jakub Karas, Upvision, Czech Republic From the 9th century onwards Prague Castle, located on the banks of the River... (read more)

Plowman Craven’s Spec for BIM Ready Modelling

One of the UK’s leading survey firms has produced a client ready specification for BIM surveys and deliverables. Richard Groom runs his eye over the content. Who better to write a BIM specification than a company that was there at the start. Plowman Craven’s (PCL) BIM specification first appeared several years ago and has just been updated and revamped. Like all good specifications it is an interface document that bridges the gap between the client and the surveyor. This bridge is simple and functional. At first glance 64 pages seems a little daunting but the contents are straightforward and easily... (read more)

Geospatial Modelling and Rights to Light

GW reports on last November’s RICS fascinating lecture by Andrew D. Thompson on how geomatics measurement techniques are being used in rights to light cases. Ever since man first began to live in clusters of buildings with windows there must surely have begun a test of neighbourliness. Don’t build too near my property and don’t obscure my view, would have been an early test of relations. In today’s highly developed and complex world we have necessarily developed highly sophisticated software tools, legislation, tables and guides to solve these problems. Andrew D. Thompson is a chartered surveyor who has specialised in... (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)

Bentley Puts Modelling in the Cloud

Is the 3D model becoming the only deliverable? For construction, is photogrammetry a better option than LiDAR? How long before modelling software can calculate costs? When should you start mentioning BIM? Richard Groom reports from a day of insight. It was only near the end of a morning of presentations at Bentley’s London offices that the acronym BIM was mentioned. The reason, I was told, is that the meaning of BIM develops with people’s understanding as they progress through Levels one to three and that for those just starting out, talk of BIM as a process can be a step...

Topcon and Bentley Bundle Reality Modelling Software with UAS

Topcon Positioning Group has introduced Topcon ContextCapture, powered by Bentley Systems, a reality modelling software solution that will be offered with Topcon unmanned aerial systems (UASs). The system is designed for mapping, construction and surveying professionals. It enables them to quickly turn simple photographs and/or point cloud data into true-to-life, highly detailed 3D models for use throughout a project life cycle. The offering will include Topcon ContextCapture Standard and Topcon ContextCapture Advanced, said Charles Rihner, vice president of the Topcon GeoPositioning Solutions Group. The standard package will be bundled with Falcon 8 and Sirius Basic/Pro and allows operators to process data from... (read more)

GeoSLAM and Bentley Systems Join Forces for Indoor Mobile Modelling

GeoSLAM, who specialise in 3D mobile mapping technology, and Bentley Systems, a global provider of software solutions for advancing infrastructure, has announced a partnership to enable the simple and fast production of hybrid reality models in any environment. Mark Reid, VP of Product Management at GeoSLAM, said “The simplicity of the ZEB-REVO handheld mobile mapping system has democratised laser scanning, enabling anybody to document their facility or construction site without being a survey expert. The next stage for us is to further improve how our results can be both interpreted and consumed within typical engineering and GIS workflows – and our partnership with... (read more)

Maptek Releases I-Site Studio 6 Point Cloud Modelling Tools

The latest I-Site point cloud processing tools from Maptek focus on the everyday needs of mine surveyors for fast and accurate volumes, conformance reporting, geotechnical analysis and CAD design. I-Site Studio software offers an expanding range of applications with increasing sophistication. I-Site Studio 6, released earlier this month, provides various new tools and requested enhancements. New CAD design tools include user-friendly preferences for snapping to angles and points. Other in-demand items include auto registration and alignment of scans, complex surface modelling, waviness analysis for geotechnical modelling and analysis. Surveyors are under pressure from all departments to quickly and safely survey... (read more)

Automatically Creating 3D City Models with Tridicon Building Finder Modelling Solution

The automatic creation of GIS-ready 3D city models and textured buildings from aerial images or LiDAR is rapidly gaining importance across the industry as national mapping agencies and municipalities are seeking to convert their cadastre or base map from 2D to 3D to support better planning, taxation, civic engagement and the growing number of smart city applications. “For many years Leica Geosystems’ tridicon City Modeller has been Europe’s leading solution to automatically create textured 3D buildings from aerial data and existing building footprints with recognition accuracies greater 90%”, says Ruedi Wagner, vice president of geospatial solutions at Leica Geosystems. “Unfortunately,...

Medway Modelling or Fitting Kent on to Two Church Hall Tables

3D modelling has become second nature to surveyors but creating a real physical model from digital data was new to Richard Groom and his colleagues at the Environment Agency’s Geomatics group. So what do you need to do to create a model big enough to fit on two church hall tables? Nowadays the task of the surveyor is normally to produce virtual models of the Earth’s terrain and the features on its surface. But a few months ago the Geomatics team in the Environment Agency were asked to procure a physical model covering Kent, South London and East Sussex. The... (read more)
