ItemDesign and development of a web-based 3D cadastral visualisation prototype(Taylor & Francis, 2015)Three-dimensional (3D) developments of land, such as complex high-rises, put enormous pressure on current land administration systems that have ad hoc approaches to 3D property management. These approaches are unable to support effective 3D storage, analysis and visualisation of property information. Effective visualisation is one of the essential components in realisation of a truly 3D cadastre. Currently, several 3D visualisation applications and cadastral prototypes have been developed around the world. However, they do not effectively represent ownership information in 3D because they have not been developed based on 3D cadastral visualisation requirements. After candidate 3D visualisation solutions were compared with user-derived visualisation criteria, a web-based 3D visualisation prototype was designed and developed. The functionality, usability and efficiency of the prototype were evaluated by potential users involved in the registration and management of property. While there was a high level of enthusiasm for the features of the prototype, the results also suggest further directions for development of 3D cadastral visualisation. © 2014 © 2014 Taylor & Francis.

Item3D visualisation of cadastre(Institution of Surveyors Victoria, 2013)The importance of managing stratified ownership land rights, restrictions and responsibilities (RRRs) are increasing due to population growth and land shortage, particularly in urban areas. As a result, stakeholders are looking for ways in order to manage land and property information more efficiently. Current approaches for managing and visualising land ownership rights are not efficient in very dense and complex urban areas. (From Introduction)

ItemCollaborative Environmental Knowledge Management(IGI GLOBAL, 2013-01-01)
This article describes the integration of a smartphone, a world viewer and a geodatabase into a collaborative virtual environment (CVE) as a knowledge management platform for use in land management. A spatial interoperability mechanism was designed for integration of these various technologies distributed in different system layers and written in different programming languages. As users may vary in their education backgrounds and understanding of advanced information technologies, the proposed platform employs existing popular spatial technologies to facilitate usage. The platform includes an iPhone™ application, a web portal based on Google Earth™ viewer and a data server, all of which may be deployed in different and distant places, allowing remote collaboration. To evaluate the usability of the platform, a case study was implemented involving a scientist, a farmer and an agricultural consultant working collaboratively, but remotely, within the system to support their farming practices, decision-making and agricultural research. Users found that the efficiency of agricultural knowledge transfer was increased, and the centralized knowledge database would also be helpful for tracking farming history and supporting agricultural research. This represents a new paradigm in agricultural knowledge management, where relationships between the three key parties are bidirectional, in contrast to the traditional knowledge transfer pattern. This paradigm can be readily extended to other environmental management contexts.

ItemUnderstanding New Landscapes: Support for Renewable Energy Planning(IGI GLOBAL, 2012-10-01)
The pace of transition to new energy sources, and away from fossil fuels, is as hard to predict as any other impact of climate change. However, it appears inevitable that a transition will be made eventually. In some countries, notably Germany and Denmark, the process is already well underway. In others it is just beginning. This article uses the situation of the state of Victoria in southern Australia to explore the possible extent of landscape change under a move to renewable energy sources, and to explore the key variables and tools for analysis and communication which will identify the consequences and support planning. A scenario for a future level of wind power generation in Victoria is proposed, potential sites identified and then the visual impact of these analyzed, not simply on a case-by-case basis but as a system of facilities across the landscape. People travelling by road, or train, will be particularly aware of the extent to which the change is pervasive and new parameters and representations are proposed for documentation of these dynamic visual landscape outcomes.

ItemDevelopment of a 3D ePlan/LandXML visualisation system in Australia(International Federation of Surveyors, 2012)The importance of managing properties and people’s interests in complex multi-level developments is increasing, due to population growth and shortage of land in urban areas. As a result, cadastral systems are under pressure to change the way they capture, register and visualise 3D data of these multi-level scenarios. However, interests in land and properties in Australia are registered and visualised through subdivision plans. This visualisation method is often paper-based and includes 2D floor plans, cross-sections and isometric diagrams. These drawings are used to represent 3D properties and associated rights. Although this has been a common practice for experts such as land registration officers and cadastral surveyors, non-expert users such as the public, lawyers and real-estate agents often find these methods difficult to understand and interpret particularly in complex high rise buildings. In order to visualise and represent properties and associated rights in 3D, a web-based prototype system was designed and developed utilising various technologies to enable a wide variety of users to explore 3D ownership rights. The prototype system’s architecture is based on a three-layer framework including, data access, process and presentation layers to represent cadastral data such as Rights, Restrictions and Responsibilities (RRRs). For developing the prototype system, the subdivision plan components and the electronic surveying and subdivision plans (ePlan) were studied and analysed. In this web-based prototype system, 3D LandXML files are converted to KML data format using Extensible Stylesheet Language Transformations (XSLT) and are visualised in the Google Earth API. Furthermore, attribute information such as bearing and distance, attached to subdivision plans, is also represented in this system. Although this prototype system is not able to visualise underground RRRs, it has potential to represent interests in land and properties through the Internet. This paper concludes that ePlan data model is able to contain 3D volume objects to store 3D interests in land and properties.

ItemNo Preview AvailableImpediments in e-Planning in local government - Indonesian case study(FIG Congress 2010 - Facing the Challenges - Building the Capacity, 2010)Spatial planning is one of the most complex government activities since it involves multi stakeholders and directly influence the way community interact with land. Main deliverables of spatial planning is regulations and maps of planning zones. They need be delivered to community effectively and transparently. Traditional method of providing this service is by using printed material which sometime impractical, immobile, difficult to maintain and limiting public access. Internet offers improvement of this process by enabling electronic delivery of planning regulations and maps, and facilitating online transaction. The implementation of e-Planning depend on several factors, among them are human resources, funding, and ICT infrastructures. This paper describes findings on what challenges and impediments faced by local government in Indonesia if they want to implement e-Planning concepts. It was base on the findings from questionnaires distributed to local planning agencies and websites survey. Three broad aspect were investigated, organization, ICT infrastructures and spatial data infrastructures. Websites survey was conducted to investigate how local government and local planning agencies make use of their websites. There are some impediments in implementing e-Planning in Indonesian local government. They include staff qualification, limitedly available funding, ICT infrastructures, and institutional arrangement. To overcome this situation, a gradual steps approach is proposed, which includes technical and non-technical matters.

ItemNo Preview AvailableStudying spatial plan in coastal urban environment - facing global threatand adapting to local condition(FIG Congress 2010 - Facing the Challenges - Building the Capacity, 2010)Spatial planning is a process involving projection on future usage of space. It requires in put from different sectors and stakeholders. Nowadays planners are also confronted with the increasing number of disasters in highly populated and economically important areas. There is a growing needs and awareness to incorporate disaster risk information in the spatial planning. One of the particular areas vulnerable to disaster is coastal urban environment. It is facing global threat from the impact of climate change and local-driven natural hazards. The paper firstly reviews literature on coastal urban cities and its characteristic. It also presents their function and importance to the society in terms of economic development and environmental sustainability. It then followed by a review on recent studies on global warming and natural hazards confronted by coastal cities as well as a conceptual frame work to reduce them. Spatial plan was proposed as a long term framework to facilitate disaster risk reduction. The paper took a case study approach using a medium size city of Semarang in Indonesia as an illustration. Three aspects were evaluated, how the spatial plan linked to the idea of disaster risk reduction, how the spatial plan address the issue of disaster risk reduction and how the spatial plan map represent disaster risk reduction effort. The findings indicate that the recent spatial planning documents in the case study area have made considerable progresses in addressing coastal disaster risk issues. The number of disaster related issues discussed in the Spatial Planning documents of 2010 to 2030 is much higher than those of 2000 to 2010. Guidance on what types of land use appropriate for hazard prone area and plans on hazard modification was provided. General directions for development restriction in hazard prone areas were also provided. Overall the city of Semarang has made considerable progress in addressing the numerous types of locally driven natural hazards, although with little reference to global threat from climate change.
