ItemThe development of a frameworkand associated tools for the integration ofmulti-sourced spatial datasets( 2006)The world of today heavily relies on spatial data to manage the natural and built environments.Monitoring and controlling the impact of human activities on environment and the impact of naturalenvironment changes (including natural hazards) on built environment is a major policy driver formany jurisdictions. The mitigation of natural hazards including tsunami, earthquake and landslide andsecuring citizens against them has become another priority of nations , especially after Indonesia’stsunami. September 11 was also a remarkable point in history which attracts attentions towardsproviding more efficient counter-terrorism initiatives to secure citizens.In many countries meeting sustainable development objectives including social cohesion andenvironment protection together with economical growth is the most overwhelming policy driver. Inthese countries most of legislations and decisions are made, if they meet sustainable developmentobjectives.All above mentioned activities try to control the natural and built environments and monitor theimpacts of one environment on the other one. To control and monitor built and natural environments,the components of these environments need to be integrated to provide the factual model of realworld. Effective access and use of spatial data has been addressed by developing SDIs (Spatial DataInfrastructures) which one of its objectives is to address and provide requirements for effective dataintegration.The effective integration of built and natural environmental datasets is an ultimate goal of manyspatial decision making systems which has not been fully achieved, however technical integration andinteroperability of multi-sourced spatial data have received much attention. The integration of multisourcedspatial data due to the diversity of data providers needs more than technical tools andconsiderations. Institutional, social, legal and policy requirements must also be taken intoconsideration in order to achieve effective integratio

ItemA template for assessing worldwide cadastral systems as part of national SDI initiatives( 2006)Many countries over the past few years have spent considerable time and energy in attempting to compile descriptions and reports in the area of land administration, without giving much attention to the role of cadastral systems and national spatial data infrastructures within a land administration system. The Permanent Committee on GIS Infrastructure for Asia and the Pacific (PCGIAP) and the International Federation of Surveyors (FIG), together with the Centre for SDIs and Land Administration have attempted to address this through the creation of a joint cadastral template that has so far been filled out by 39 countries. The template collects descriptions of national cadastral systems as part of National Spatial Data Infrastructure (SDI) initiatives on a broad basis and the information is made publicly accessible on the web. The information can be used for comparing and assessing land administration and cadastral systems worldwide, in order to help countries re-engineer and implement their systems to address future needs. This paper aims to outline the concept and theory behind the development of the cadastral template and its relationship with National SDI initiatives and how it can help spatial information practitioners in improving and re-engineering their infrastructure and systems. Analysis of the data gathered from the completed templates is currently being undertaken with some overall results presented and future areas of work identified.

ItemCreating an enabling platform for the delivery of spatial information( 2005)The ability of single organisations or government agencies to deliver services and tools that meet user needs withinthe spatial information market is shrinking. Users now require precise spatial information in real-time about realworldobjects. This requires governments and industry to work together to create such products and services. Theproblem in Australia however, is that much of the spatial information needed to create these services resides withingovernment agencies which is often difficult for industry to access.Governments are moving forward in relation to creating policies and initiatives which open up some of thisinformation to the public. They are also creating whole-of-government initiatives such as Western Australia’sShared Land Information Platform (SLIP) and Information Queensland which aim to make governmental spatialinformation accessible across all government agencies. What is lacking however is the ability for industry to engagedirectly with these whole-of-government/cross-agency initiatives. There is a need to create an infrastructure orenabling platform linking government and private industry from which applications and services can be leveragedand value added, providing the ability to grow the private sector and spatial information industry as a whole.This paper aims to describe the issues surrounding the creation of an enabling platform linking governments spatialinformation initiatives and the private sector. It also explores the relationship between top-down research required tospecify strategic goals and vision, prioritize plans, resolve policy issues and build enabling framework and thebottom-up commercialisation required to promote various local initiatives and build application-specific andenterprise-wide databases and services. This is done through an analysis of the concept of a virtual jurisdiction,outcomes of case studies undertaken within five Australian jurisdictions on spatial data infrastructure and spatialinformation initia

ItemIssues in defining the concept of a marine cadastre for Australia( 2003)Australia's ratification and subsequent implementation of the United Nations Convention on the Law of the Sea has given the government responsibility for the management of a marine environment double the size of the country's land mass. Such a management initiative must take into account the economic, social and environmental needs of marine stakeholders, as well as incorporating international and national tools of governance. In the terrestrial environment, it is the cadastre and initiatives such as the creation of the Australian Spatial Data Infrastructure (ASDI) that are facilitating greater decision making in areas such as sustainable development. The ability of such tools and initiatives to facilitate effective decision-making and spatial data access mechanisms within the marine environment has given rise to research into a marine cadastre. Such a cadastre aims to define, visualise and realise legally defined maritime boundaries and the rights, restrictions and responsibilities attached to them. With this in mind, this paper aims to identify and quantify the various themes which are driving the development of an Australian marine cadastre, as well as attempting to define the concept of a marine cadastre through an investigation into the current international research into marine cadastral systems.

ItemDevelopment of a Virtual Australia Utilising an SDI Enabled Platform( 2005)Spatial Data Infrastructure (SDI) which is an evolving concept and can be viewed as anenabling platform linking data producers, providers and value adders to data users. With thisin mind, many nations and jurisdictions are investing in developing such platforms andinfrastructures that enable their stakeholders to work together in a more mutual approach tocreate distributed virtual systems that support better decision-making. The success of thesesystems depend on collaboration between all parties and need to be designed to supportefficient access, retrieval and delivery of spatial information to where it is needed.Within Australia, through the Cooperative Research Centre for Spatial Information (CRC-SI),there is a vision to provide a single entry point to SI, modeling and visualization tools, makingspatial information available and useful to all - at any time and in any place. This requires theseamless integration of SDIs at different levels including state and national to form a virtualjurisdiction such as Virtual Australia, providing a foundation for identifying best practice andkey performance indicators of SDIs in terms of their policy, technology and institutionalframeworks.This paper will discuss how SDIs can be used as an enabling platform in the construction anddelivery of a Virtual Australia, based on the SDI hierarchy model where data flows withminimal impediments within and between state and federal/national levels. The benefits ofVirtual Australia will be more than just the representation of feature based structures of theworld, it will also include the administration and institutional aspects of such features,enabling both technical and institutional aspects to be incorporated into decision-making. Thisis an aspect of research identified as more challenging than complex technical issues.
