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
Read this interview with five pioneers in the field for insights into the best ways to introduce drones into your business model. 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... (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)

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)

Smart Surveyors: Developments and Trends from the FIG Working Week 2020

Some of the challenges demanding innovative surveying approaches and technologies are rapid urban growth, smart energy, cleaner mobility, and ‘land rights for all’. Sensing technologies, spatial data processing methods, and related approaches are already available. However, the question is how to use and improve them to become future proof, smart surveyors? Only ten years left to achieve the SDGs for a sustainable future. How can smart surveying contribute? To answer these questions, the papers of the FIG proceedings were analysed by the author-team.In this short article, we present the main trends distilled and the papers we refer to, represent these...

GNSS and Heavy Equipment

Financial Benefits of Telematics and Machine Control
Heavy equipment represents a major capital cost for companies in industries such as construction and agriculture. In recent years Global Navigation Satellite System (GNSS) technology, which uses signals from US Global Positioning System and the Russian Glonass satellite system constellations, has been used to improve fleet efficiency. Many companies may hesitate to invest in the technology because management is unaware of its benefits. Such hesitation has only increased during the current global economic downturn. However, recent evidence has emerged to demonstrate the measurable impact GNSS technology may have on company profits.   Equipment telematics, the wireless exchange of electronic information...
