Exceeding All Limits

Intergeo 2005 Düsseldorf, Germany – A Preview
This year’s Intergeo, to be held at the Exhibition Centre in Düsseldorf, Germany from 4th to 6th October, is expected to exceed all limits. With opening extended to three whole days and exhibition space to 10,000m2, it certainly looks as though big things are expected. And if organiser Hinte-Messe predictions prove correct, some 17,000 visitors and 1,500 conference delegates will attend. Nearly five hundred exhibitors have booked a stand at the trade-fair. It is not only in statistics limits are being pushed. The theme of ‘Exceeding limits’ reflects a wish to increase awareness of European expansion, globalisation and its effect... (read more)

Capturing Geospatial Data from Vehicle Platforms

Jacobs’ Journey
Jacobs Geomatics provides support and consultancy to the company’s wider design and engineering services. In recent years Jacobs’ UK geomatics team has been involved in increasingly large infrastructure schemes, typically supporting preliminary and detailed design phases of projects. This requires advising on solutions and the subsequent provision of suitable geospatial data. As the projects have grown in scale and complexity, the company has increasingly sought to supplement traditional topographical survey capture techniques with rapid data techniques such as terrestrial laser scanning, aerial photography and Lidar. Over the past three to four years, Jacobs has also become increasingly involved in vehicle-mounted... (read more)

How Can Establishing a UAV Fleet Help Your Business Take off?

Best Practices in Drone Mapping
Unmanned aerial vehicles (UAVs or 'drones') are increasingly becoming the solution of choice and have indeed proven to be a disruptive force across a multitude of industries in the past decade, including for the geospatial surveying profession. But will drones really provide all the answers to your mapping challenges? We interviewed five pioneers in the field to take us beyond the hype, explaining the lessons they have learned from the frontline and sharing their insights on the best ways to introduce UAVs into your business model. What type of work can UAVs be used for? UAVs can serve mapping and... (read more)

Mobile GIS Systems

Technical and Business Features
Today the computer power of handheld devices is comparable to the desktop computers of a few years back. Together with rapid adoption of the internet, this progress has triggered fitting mobile GIS systems into work processes. Mobile GIS is a means of geo-data collection using GNSS positioning, GIS functionality, wireless connection and mapping, all integrated in one compact device. In tandem with this month’s product survey (page 28), the author gives a detailed outline of the technical and business features of mobile GIS systems. Many work processes start with dispatching digital geo-data from the central GIS to the plotter next... (read more)

High-precision GNSS Receivers

The benefits and availability of new signals and systems
What will the new GNSS signals bring to the user of high-precision receivers? This article provides a brief overview of what users can expect from GNSS systems that are currently in the modernisation/development stage, looking at new signals and emerging techniques including coverage of GNSS developments such as GPS, Galileo, GLONASS and Compass/Beidou. In view of the planned timeframe, what we can do to improve the robustness of our receivers with a special focus on interference and the upcoming solar maximum? The use of high-precision GPS for surveying applications has increased dramatically over the last decade. GPS receivers can provide... (read more)

UAS Campus Survey Project

Students Capturing Spatial Information Needs
Texas A&M University-Corpus Christi, home to the largest geomatics undergraduate programme in Texas, USA, is currently undergoing a major university expansion. Both the main Island campus and the Momentum campus, which is a smaller developing campus, are undergoing extensive construction projects. The university’s Conrad Blucher Institute for Surveying and Science (CBI) was tasked with devising a comprehensive way to capture the spatial information needs related to the expansion. This effort is ongoing and is being conducted by students, providing them with a unique survey experience. The initial task was to perform a complete ground survey of all existing infrastructure at... (read more)

Using 3D Printer Technology to Represent Survey Information

The Art of Bathymetry
Great advancements have been made in three dimensional printing over the last few years and have made an impressionable impact across a variety of industries. 3D printing's versatility can be incorporated into any industry that has some form of three dimensional design. An exciting application is to model point clouds from survey techniques to create three dimensional scaled models for visualisation and communication. This article explores a new medium using 3D printed technology.  (By Andrew Ternes, Port of Melbourne and Dr Daniel Ierodiaconou, Deakin University, Australia) Over the last few years great advancements have been made to all forms of...

Ortho-imagery: Geometric Accuracy Assessment

Towards Product Specification for Urban Areas
Anomalies such as building-lean result from the processing of traditional orthorectified imagery and this limits its use in urban areas. However, the arrival of digital sensors has meant fully orthorectified products coming onto the market. The authors test the positional accuracy of fully orthorectified imagery for urban areas and suggest a product specification. Orthophoto production used to be mostly limited to medium and small-scale applications, and even in the 1990s this market remained so underdeveloped that line-map restitution from stereo imagery was cheaper than producing large-scale orthophotos. Orthorectification transforms an image from a perspective projection to an orthogonal one; the... (read more)
