The decade immediately after the end of the Second World War gave rise to three key societal developments in Australia—a dramatic increase in the birth rate and car ownership, plus an acceleration of the suburbanisation process. Five decades later, these three developments would converge and give rise to a new public policy problem: a spatially dis...

Advances in microelectronics and the increasing use of digital mobile technologies associated with location based service (LBS) provision and consumption, have started to profoundly change the way we make decisions about when, how and where we do things. Microelectronics based modes of communication have extended our capacity to escape the ‘spatial...

Over the past decade, researchers have refocused their attention upon the interconnection between locationally disadvantaged communities and poor transport services in order to better understand social exclusion. Limited access to private and public transport has often been identified as a major contributing factor to social isolation and economic...

In order to assist the surveying industry face unprecedented international economic, environmental and governance challenges the educational challenges of the GPS/Surveying discipline need to be confronted. These challenges centre on the alignment of curriculum and assessment with new technology tools to overcome conceptual and technical complexity...

Salahuddin Ahmad, Gang-jun Liu and Benno Engels (2009) A Simple GIS-based Method for Transferring Census Data from CCDs to MBs, Spatial Sciences Institute Biennial International Conference, Adelaide, Australia, 28 September – 2 October 2009. Abstract: More spatially distributed description of local community’s characteristics is desirable for many...

Global natural disasters have caused billions of dollars of property and infrastructure damages, unexpected disruption to socioeconomic activities and tragic loss of human lives each year. It is of paramount importance to collect, maintain and manage detailed and accurate records of disastrous events for an effective risk assessment and mitigation...

With the rapid development of spatial information infrastructure in US, Europe, Japan, China and India, there is no doubt that the next generation Global Navigation Satellite Systems ( GNSS) will improve the integrity, accuracy, reliability and availability of the position solution. GNSS is becoming an essential element of geospatial infrastructure...

As in many parts of the world, long-term excessive extraction of groundwater has caused significant land-surface subsidence in the residential areas of Datun coal mining district in East China. The recorded maximum level of subsidence in the area since 1976 to 2006 is 863 mm, and the area with an accumulative subsidence more than 200 mm has reached...

AbstractMore effective environmental pollution control and management are needed due to the increasing environmental impacts from a range of human activities and the growing public demands for a better living environment. Urban air pollution is a serious environmental issue that poses adverse impacts on the health of people and the environment in m...

With the rapid development of spatial satellite-based infrastructure in US, Europe, Japan, China and India, there is no doubt that the next generation Global Navigation Satellite Systems (GNSS) will significantly improve the integrity, accuracy, reliability and availability of the position solution. GNSS is becoming an essential element of personal...

With the rapid development of spatial infrastructure in US, Europe, Japan, China and India, there is no doubt that the next generation Global Navigation Satellite System (GNSS) will improve the integrity, accuracy, reliability and availability of the position solution. GNSS is becoming an essential element of personal, commercial and public infrast...

This spatial and temporal heterogeneity in the distribution of Anopheles mosquitos were studied during August 2001 to December 2002 in three villages Ban Khun Huay, Ban Pa Dae, and Ban Tham Seau, in northwestern Thailand in Mae Sot district, Tak Province. The three Karen villages are located about 20 km east of the city of Mae Sot near the Myanmar...

We sampled 291 bodies of water for Anopheles larvae around three malaria-endemic villages of Ban Khun Huay, Ban Pa Dae, and Ban Tham Seau, Mae Sot district, Tak Province, Thailand during August 2001-December 2002 and collected 4,387 larvae from 12 categories of breeding habitat types. We modeled surface slope and wetness indices to identify the ext...

Given a set of remotely sensed images with different spatial and spectral resolutions, information preserving techniques of pixel-level image fusion can be used to generate a synthesised image that maximises the preservation of both the spectral and the spatial information available from the source images. These techniques have the potential for im...

Land use in long-settled areas outside zones especially affected by climatic change and not much or long subject to rapid economic development can be shown to reflect sustainable practice. The research reported here used terrain characteristics of such areas (over five land-use types) to establish a benchmark framework for assessing land-use suitab...
