GPS infrastructures that have been established in Malaysia are mainly served as a ground control stations for cadastral and mapping purposes. Another element that has not been utilised is the height component due to its low accuracy. Conventional levelling is still the preferred method by the land surveyors to determine the stations orthometric height (H) with a proven accuracy. Therefore, Department of Survey and Mapping Malaysia (DSMM) has embarked the Airborne Gravity Survey, with one of the objectives is to compute the local precise geoid for Malaysia within centimeter level of accuracy. With the availability of the precise geoid, the “missing” element of GPS system is solved.
Land administration systems evolved from a focus on core functions of regulating land and property development, land use controls, land taxation and disputes (Dale & McLaughlin, 1999) to an integrated land management paradigm designed to support sustainable development (Enemark et al., 2005).
EU and India seal EU and India seal their agreement
After intensive exchanges held since January 2004, negotiations on India’s participation in Europe’s satellite radio navigation programme fi nally reached approval. The agreement, initialled today in New Delhi at the occasion of the EU-India Summit in the presence of UK Prime Minister Tony Blair as EU Presidency, European Commission President José Manuel Barroso and Indian Prime Minister Manmohan Singh, will ensure the availability of highest quality Galileo services in India as well as cooperation to establish regional augmentation systems based on EGNOS and GALILEO. Welcoming the outcome of the negotiations, Vice-President of the European Commission Jacques Barrot said: “This is another important step for the development of GALILEO as an international programme, but also a major milestone in the EU/India partnership”. The agreement was initialled by Mr Francisco Da Camara Gomes, Head of the EC Delegation in India, representing the European Union, and Mr G. Madhavan Nair, Secretary, Department of Space, representing India. Considering that India has well proven capabilities in space, satellite and navigation related activities, the agreement will provide a positive impulse for India and European industrial cooperation in many high tech areas.
India is the fourth country joining the GALILEO programme, after the signature of agreements with China, Israel and Ukraine. Discussions are also under way with Argentina, Brazil, Morocco, Mexico, Norway, Chile, South Korea, Malaysia, Canada and Australia.

Hurricane Katrina and its aftermath
Hurricane Katrina severely pounded the Gulf Coast of U.S. with great force at daybreak on the 29th of August. Arriving with 145 mile an hour wind speed, the storm left more than a million people in three U.S. states without power and submerged highways. Hurricane Katrina, formed in the Bahamas in mid-August and struck South Florida on 25 August, killing nine people and leaving a million more without electricity. European Space Agency’s multisensor Envisat satellite has gathered a unique view of Hurricane Katrina in the Gulf of Mexico. Envisat simultaneously acquired these images at 1550 UTC (1150 US Eastern Daylight Saving Time) on 28 August, with its Medium Resolution Imaging Spectrometer (MERIS) and Advanced Synthetic Aperture Radar (ASAR). While an optical image shows characteristic spiralling cloud patterns, a simultaneous radar observation pierces through the clouds to show how Katrina’s 250- kilometre-an-hour winds scour the sea surface. www.sciencedaily.com
In Great Britain most geodata that provides the reference and geographic context for more targeted user datasets created by individual organisations is issued by Ordnance Survey®. These user datasets may include Sites of Specifi c Scientifi c Interest or Basic Land and Property Units. Based on this reference data, users often integrate other datasets, such as statistical tables or their own geo-datasets, to support analysis and decision making. Others may collect geo-datasets by using Global Positioning System (GPS) equipment: the location of street furniture, for example. In all cases it is vital that data from different sources fi ts together spatially to enable the joint use and analysis.
Indigenous community in Australia maps cultural data
Traditional landowners in north west Queensland, Australia will soon be recording and mapping their own cultural heritage sites under a new arrangement with the State Government. The Mt Isa-based Mitakoodi-Juhnjlar aboriginal people will be the first to be taught the technical skills needed to gather their own data. They will be learning skills on using GPS programs and secondly being able to record those results onto software which will then go to offi cial authorities for insertion into the official maps.

This article investigates the use of artificial neural networks for developing an alternative integration scheme of low cost Microelectromechanical System (MEMS) Inertial Navigation System (INS) and Global Positioning System (GPS) for vehicular navigation applications. The primary objective is to overcome the limitations of current INS/GPS integration scheme and improve the positioning accuracy during GPS signal blockages. The results presented in this article indicated that the proposed technique was able to provide 47% and 78% improvement in terms of positioning accuracy during GPS signal blockages.
Bangkok to introduce GPS to its fleet of taxis
Bangkok has opened the first of 150 new electronic taxi stands that will allow pedestrians to summon a taxi by pressing a green button, signaling a dispatcher to send a taxi. The devices will display the estimated arrival time and license plate number of the approaching taxi. Taxis will be equipped with GPS as part of the service. The first arch-roofed electronic taxi stand was unveiled last week outside a superstore on the city’s Phahonyotin Road, while the remaining stands are expected to be installed across the city by November. Besides helping Bangkok pedestrians easily hail taxis, the stands are meant to keep cab drivers from wasting fuel by driving around the city in search of fares. www.chinapost.com.tw
Road Construction Project uses positioning technology
Trimble announced that it has been selected as the preferred supplier of machine control and survey equipment for Thiess John Holland, the lead contractor building Australia’s largest road project¯EastLink in Melbourne. With total construction costs of AU$2.5 billion (US$1.9 billion), the scale of work required for timely completion of Melbourne’s EastLink is beyond that ever tackled before on any single infrastructure project in Australia. EastLink’s three-lane, freeway-standard road is expected to be built over three and a half years. Construction includes two million square meters of paved road, more than eighty bridges, seventeen interchanges and 1.6 kilometers three-lane twin tunnels. The project will deliver Melbourne’s second fully-electronic tollway, comprising about 45 kilometers of freeway-standard road connecting the city’s eastern and south-eastern suburbs.
