ItemGroundhog day, ..., again! [Review of the book Geographic information science: mastering the legal issues]( 2006)The disappointed reviewer concludes that this text is no better than the previous text by the author (also reviewed by the reviewer seven years ago in the Law Institute Journal). This latter book is much less expensive than the earlier one that carried a RRP of $215...Reviewer.

ItemPoorly defined boundaries of a nebulous frontier( 1999-06)The disappointed reviewer concludes that this text, one of the fewcovering GIS and law, does not live up to its promise and certainly doesnot justify the price asked. The recommendation is for intendingpurchasers to consider competing texts or await the publication of asecond edition that has not been deprived of the care that a book on thisimportant subject matter deserves.

ItemDeveloping and testing a 3D cadastral data model: a case study in Australia(ISPRS, 2012)Population growth, urbanization and industrialization place more pressure on land use with the need for increased space. To extend the use and functionality of the land, complex infrastructures are being built, both vertically and horizontally, layered and stacked. These three-dimensional (3D) developments affect the interests (Rights, Restrictions, and Responsibilities (RRRs)) attached to the underlying land. A 3D cadastre will assist in managing the effects of 3D development on a particular extent of land. There are many elements that contribute to developing a 3D cadastre, such as existing of 3D property legislations, 3D DBMS, 3D visualization. However, data modelling is one of the most important elements of a successful 3D cadastre. As architectural models of houses and high rise buildings help their users visualize the final product, 3D cadastre data model supports 3D cadastre users to understand the structure or behavior of the system and has a template that guides them to construct and implement the 3D cadastre. Many jurisdictions, organizations and software developers have built their own cadastral data model. Land Administration Domain Model (DIS-ISO 19152, The Netherlands) and ePlan (Intergovernmental Committee on Surveying and Mapping, Australia) are examples of existing data models. The variation between these data models is the result of different attitudes towards cadastres. However, there is a basic common thread among them all. Current cadastral data models use a 2D land-parcel concept and extend it to support 3D requirements. These data models cannot adequately manage and represent the spatial extent of 3D RRRs. Most of the current cadastral data models have been influenced by a very broad understanding of 3D cadastral concepts because better clarity in what needs to be represented and analysed in the cadastre needs to be established. This paper presents the first version of a 3D Cadastral Data Model (3DCDM_Version 1.0). 3DCDM models both the legal and physical extent of 3D properties and associated interests. The data model extends the traditional cadastral requirements to cover other applications such as urban planning and land valuation and taxation. A demonstration of a test system on the proposed data model is also presented. The test is based on a case study in Victoria, Australia to evaluate the effectiveness of the data model.

Item3D land and property information system: a multi-level infrastructure for sustainable urbanisation and a spatially enabled society(GSDI, 2012)Urbanization is an inevitable part of the economic development process for any country and is considered a global phenomenon (World Bank, 2009). Currently, 50 percent of the world’s population resides in urban areas; by 2050, this ratio will reach 70 percent. This concentration of growth will place increasing pressure on land resources that are already in high demand. The achievement of sustainable development goals is therefore predicated on achieving sustainable urbanization. This paper considers the specific challenges of urbanization on land and property and the development of a three‐dimensional (3D) land and property information system as a new tool for managing rights, restrictions and responsibilities as part of a modern land administration system. This system aims to provide an infrastructure that allows for the integration of information pertaining to the built and natural environments using land and property as a common framework. By facilitating access, discovery, and sharing of land and property information, this system will provide a multi‐level infrastructure to link government, industry and citizens to support the functions of a modern land administration system which provides the foundation for realising a spatially enabled society and achieving sustainable development.
