About ten years ago it became clear that in many parts of the world airspace was approaching saturation point. Air transportation was plagued by delays, and safety had begun to be compromised. The existing outmoded groundbased radar systems, already stretched to the limit, were hardly able to cope. In the US, there are around 50,000 […]

Laser Scanning for Mine Safety
SIMON ARTHUR and DAVID ELDRIDGE In an effort to enhance mine safety, the management of Beaconsfield gold mine, at Beaconsfield in north eastern Tasmania, has purchased a new laser scanning system. It can rapidly scan the underground workings. What’s more, it is remote-controlled, so the operators are never exposed to danger. Historically, Beaconsfield’s mine surveying […]
Choosing an Airborne Laser Scanner
WAL MAYR Airborne laser scanning is a relatively recent technology that has revolutionised the capture of terrain information. It involves the emission and measurement of laser pulses from an airborne scanner. Until recently, it was mainly used to capture large areas of relatively low-resolution digital terrain data. However, in the past few years a range […]
Earthquake Prediction After Sichuan
PAUL GRAD A massive earthquake hit China’s Sichuan Province on 12 May. As aftershocks and landslides threatened further loss of life and property damage, a team from the University of New South Wales joined several other organisations to provide detailed satellite images of the affected area. The earth tremor was of magnitude 8.0 on the […]
Monitoring Landslides in New Zealand
PAUL GRAD A landslide monitoring system now under development in New Zealand is probably the most detailed in the world. GNS Science, a New Zealand government owned research organisation, is developing the system in the township of Taihape in central North Island. GNS Science operates a hazard monitoring system network called GeoNet, which is […]
Re-Aligning the Cadastre
Bundaberg is located at the southern tip of the Great Barrier Reef in the heart of a rich sugar and horticultural belt. The name is well known – it is the home of the famous Bundaberg Rum. Just four hours drive north from Brisbane, the city is home to 46,000 people. It services 120,000 […]
Designing Maps for the Web
JOSE DIACONO Good cartography for online mapping is about what you show, how you show it and how fast. No matter how current and correct your GIS information, such distractions as slow display, spidery fonts, obscure icons or cluttered symbology will turn off an increasingly demanding public. They just need answers. Unfortunately, however, it is […]
Mapping the Sydney Underground
JON FAIRALL Tough new penalties await contractors who interrupt electricity and gas supplies in Sydney. The legislation, which allows for five-year jail terms, has passed through the New South Wales Parliament and is now awaiting Royal Assent. It follows a series of power failures in Sydney’s central business district in March. The legislation is a […]
Victoria’s Notification and Editing System
JOSE DIACONO As a rule, 75 per cent of the cost of a spatial system is in the data. Inevitably, some of this data will change or be wrong, so there are huge benefits to be gained by putting the people who find the problems in touch with those who fix them. At the […]
NSW Introduces CORS Network
JONATHON POWERS The NSW Department of Lands is rolling out a $6 million electronic survey infrastructure. When completed, the entire state will be covered by a network of continuously operating reference stations that receive signals from navigation satellites. The project will increase the absolute accuracy of the survey control network. Currently, the survey […]
