Blue Marble releases fully managed version of GeoCalc SDK

By Ivan Leonardi | 14h27, 22 de October de 2013

Blue Marble Releases Global Mapper 14.24 Blue Marble releases fully managed version of GeoCalc SDKBlue Marble Geographics is pleased to announce the release of a fully managed .NET version of the GeoCalc 6.6 software development kit (SDK). Now .NET developers can get all of the accuracy and power of the GeoCalc toolkit in a fully managed .NET control. Blue Marble’s geospatial data manipulation, visualization and conversion solutions are used worldwide by thousands of GIS analysts at software, oil and gas, mining, civil engineering, surveying, and technology companies, as well as governmental and university organizations.

GeoCalc is a fully object-oriented class library for software developers. Available on a number of platforms, not only does it support a massive amount of geodetic objects out of the box but the tool also has a direct connection to the OGP’s EPSG Geodetic Parameter web registry. This allows you to directly update your EPSG definitions whenever you need it and to supplement our already huge database with even more objects for coordinate transformation. Blue Marble’s geodetic toolbox leverages an XML data source, enabling secure and powerful data transformation management through interfaces and logic that allow you to lock down your datasource via password protection. The toolkit includes a variety of tools for improving data quality management from a development level allowing the software developer to work with the survey expert to provide powerful coordinate transformation software. With the release of the fully managed .NET platform, developers now can get all of the accuracy and power of the GeoCalc toolkit in a fully managed .NET control.

“This fully managed version of GeoCalc has come about from working closely with a number of our developer customers over the past year,” stated Blue Marble President Patrick Cunningham “We’re pleased to make powerful, reliable coordinate transformation available for any software environment and happy to assist our customers at the same time. When we say customer driven development, we mean it.”

The GeoCalc fully managed SDK is built on Microsoft’s 4.0 .NET architecture. This means all of the memory management details are handled entirely by the .NET virtual machine and the CLR (Common Language Runtime). Using this standard Windows framework increases security, performance, and usability for anyone working inside the latest Microsoft development environments. This new version of GeoCalc streamlines the development process as 32 and 64 bit compatibility issues are handled entirely by Visual Studio, and the new code base means only one application needs to be delivered for both environments. The single DLL redistributable framework makes windows deployment much easier in many cases, lowering development costs and speeding up time to market.

Astrium unveils first WorldDEM Sample Data

By Alexandre Scussel | 14h05, 22 de October de 2013

Astrium, the world’s second-ranking space company, has released the first WorldDEM sample datasets for evaluation purposes, enabling potential customers to begin testing data for various applications including line-of-sight analysis, 3D visualisation or orthorectfication of satellite imagery. The sample data also facilitates testing of the Digital Elevation Models (DEMs) in the users’ data management environments. After evaluating the data, users can provide feedback to Astrium Services, helping to enhance the WorldDEM offering and its services.

Astrium unveils first WorldDEM Sample Data Astrium unveils first WorldDEM Sample DataThis is an opportunity for potential customers to test the WorldDEM data and experience firsthand the remarkable level of accuracy of the WorldDEM, that will surpass that of any satellite-based global elevation model available today, said Vark Helfritz, director of GEO-Information Corporate Development at Astrium Services.

The WorldDEM sample data, feature two different variants:

- The basic Digital Surface Model (DSM), including the heights of all natural and man-made objects;
- DSM hydro, where water body features derived from the radar data are extracted and edited.

WorldDEM is based on data acquired by the German high-resolution radar satellites TerraSAR-X and TanDEM-X and will be available starting in 2014. The two satellites acquire up to four coverages of the Earth’s surface. The combined processing of these various data takes will ensure the global consistency and quality of the final WorldDEM product.

The first and second coverages of the Earth’s land surface for WorldDEM have been completed, with the second coverage achieved in mid-2013. TerraSAR-X and TanDEM-X are now acquiring additional data takes of challenging terrain such as high-altitude mountain ranges. For this final stretch of the acquisition campaign, the formation of TerraSAR-X and TanDEM-X was revised. At the start of the mission TanDEM-X circled around TerraSAR-X in an anti-clockwise direction, following the satellite swap it is now clockwise. This change of formation was necessary to view complex mountainous terrain from a different viewing angle, eliminating missing information due to radar effects.

The TerraSAR-X and TanDEM-X missions are implemented as a Public Private Partnership between the German Aerospace Center DLR and Astrium. Astrium Services holds the exclusive commercial marketing rights for the data and is responsible for the adaptation of the elevation model to the needs of commercial users worldwide.

Gaming industry adapts mobile mapping technology

By Ivan Leonardi | 13h55, 22 de October de 2013

Computer gaming systems are getting closer to reality itself. To capture this  reality, software developers need to create accurate environmental settings for these games. Find out how racing game developers turned to Topcon’s mobile mapping technology.

IMG 1224 frei klein Gaming industry adapts mobile mapping technologyLandScope Engineering have developed a survey method that is capable of delivering a high resolution and accurate track survey, with minimal track shut-down to track activities. Ideally these surveys capture the various track set ups including the temporary race infrastructure such as signage and camera units. Furthermore the survey solution had to consider the logistical implications of surveying multiple tracks, in multiple geographies over several months – clearly calling for portability and ease of remote set-up.

Accuracy and detail make the game

The accuracy and detail of these virtual representations of race tracks have great bearing on the gaming experience with users otherwise reporting non-conformances such as missing track detail and misrepresentation of corner geometry. Exceptionally detailed models of the cars and motorbikes – in terms of graphics, sound and dynamics – can be compromised by inaccurate and low resolution track environments. Traditionally track surveys have been conducted with various straight forward techniques employing cameras, tape measures and, if lucky, handheld GPS, resulting in oversimplistic environmental representation.

Mobile Mapping Silverstone racetrack

Having considered the various survey and logistical requirements LandScope Engineering deployed the Topcon IP-S2 mobile mapping system to Silverstone. With data acquired over multiple laps the survey works were completed within forty minutes and the results exceeded all expectations of both the survey and computer modelling teams. Repeatable accuracies reviewed from lap to lap were in the order of 10-20 mm in the vertical.

Further processing within Topcon GeoClean software allows the matching of point clouds from multiple passes allowing the generation of both an accurate and seamless point cloud model – ready for export to 3D modelling packages as either point cloud or a generated mesh.

In addition to the point cloud data, the fully geo-referenced panoramic imagery gave valuable input to the game modelling process in communicating colour and texture data to the modelling teams. Thus removing the need for extensive photographic campaigns.

New workflow processes in gaming industry

The use of Mobile Mapping data acquisition created new possibilities in the gaming industry. LandScope Engineering and its partners develop innovative software systems and workflow processes to automatically extract carriageway and track geometry from point cloud models with a direct feed in to modelling systems such as AutoDesk 3DSMax.

Data acquired with the Topcon’s IP-S2 and processed by LandScope Engineering have become the ultimate reference for race track model generation. Modern racing games give players the closest feeling to a real race, and realistic game-experience is the only thing that counts.

ESA’s Goce mission comes to an end

By Ivan Leonardi | 13h38, 22 de October de 2013

GOCE in orbit node full image ESA’s Goce mission comes to an endAfter mapping variations in Earth’s gravity with unprecedented detail for four years, the Goce satellite has run out of fuel and the end of mission has been declared.

Since March 2009, the Gravity field and steady-state Ocean Circulation Explorer – Goce – has been orbiting Earth at the lowest altitude of any research satellite.

Its ‘gradiometer’ – the sensitive instrument measuring gravity in 3D – was the first in space and has mapped variations in Earth’s gravity with unrivalled precision. The result is a unique model of the ‘geoid’, which is essentially the shape of an ideal global ocean at rest and therefore critical for accurate measurements of ocean circulation and sea-level change.

Goce has provided dynamic topography and circulation patterns of the oceans with unprecedented quality and resolution, improving our understanding of the dynamics of world oceans.

Scientists further exploited Goce’s data to create the first global high-resolution map of the boundary between Earth’s crust and mantle – called the Moho.

The satellite also became the first seismometer in orbit when it detected sound waves from the massive earthquake that hit Japan on 11 March 2011.

Although the planned mission was completed in April 2011, the fuel consumption was much lower than anticipated because of the low solar activity, enabling ESA to extend Goce’s life.

In August 2012, the control team began to lower the satellite’s orbit – from about 255 km to 224 km. Dubbed ‘Goce’s second mission’, the lower orbit increased the accuracy and resolution of Goce’s measurements, improving our view of smaller ocean features such as eddy currents.

“This innovative mission has been a challenge for the entire team involved: from building the first gradiometer for space to maintaining such a low orbit in constant free-fall, to lowering the orbit even further,” said Volker Liebig, ESA’s Director of Earth Observation Programmes.

“The outcome is fantastic. We have obtained the most accurate gravity data ever available to scientists. This alone proves that Goce was worth the effort – and new scientific results are emerging constantly.”

On 21 October, the mission came to a natural end when it ran out of fuel. The satellite is expected to reenter Earth’s atmosphere in about two weeks.

Data acquisition and satellite operations will continue for about two more weeks until its systems stop working because of the harsh environmental conditions at such a low altitude. At this point, the satellite will be switched off, marking the end of activities for the Goce flight control team.

While most of the satellite will disintegrate in the atmosphere, Some smaller parts are expected to reach Earth’s surface. When and where these parts might land cannot yet be predicted, but the affected area will be narrowed down closer to the time of reentry.

An international campaign is monitoring the descent, involving the Inter-Agency Space Debris Coordination Committee. The situation is being continuously watched by ESA’s Space Debris Office, which will periodically issue reentry predictions.

ESA will keep its Member States and the relevant authorities permanently updated.
