the relation between structured cultural heritages and condominium towards 3d Cadastre
Survey Review, 2016Co-Authors: Yakup Emre Coruhlu, Osman Demir, Okan Yildiz, Mehmet CeteAbstract:In this study, structured cultural heritages were investigated mainly in the light of three-dimensional (3D) Cadastre and secondarily e-governance in the name of handing them down safely to future generations. The aim of the study is to give examples of cultural assets/heritages, 3D Cadastre, condominium for realising 3D Cadastre both legally and technically, and expectations of 3D Cadastre, e-governance in Turkey, land management implementations and what the situation for normal buildings is and also what should be done for immovable cultural heritages. Some cultural assets to be protected have been utilised as both trade centres and tourism centres from the past to the present. These buildings, which were generally built in Ottoman times, have been used or occupied owing to repairs and restoration projects in Turkey. The registration of immovable cultural assets, which are immovable properties that are accepted and registered as cultural heritages on the land registry as 3D land objects is extremely imp...

progress of cost recovery on Cadastre based on land management implementation in turkey
Survey Review, 2015Co-Authors: Osman Demir, Bayram Uzun, Yakup Emre CoruhluAbstract:AbstractThe General Directorate of Land Registry and Cadastre (GDLRC, in Turkish TKGM), which is under the authority of the Prime Ministry of the Republic of Turkey, has started taking advantage of the private sector for the production of Cadastre products that have been more effective and economical since 2005. During this progress, the Licensed Surveying Engineer and Bureau (LSEB, in Turkish LIHKAB) was established. Change operations on demand after the finishing of Cadastre works were passed on to the LSEB. In addition, the GDLRC has started accelerating the data quality to meet the Cadastre data standard of the European Union. Besides, since 1993, the information-produced Cadastre maps and projects have been sold to whoever they may concern by way of GDLRC through the concept of revolving funds. Through this concept, it is intended that experiences of revolving funds in our country would be beneficial for transferring this matter to the concerned country. In this sense, the progress of cost recovery i...

the graphical Cadastre problem in turkey the case of trabzon province
Sensors, 2008Co-Authors: Osman Demir, Yakup Emre CoruhluAbstract:Cadastral projects in Turkey have been accelerated in recent years by the involvement of the private sector. These projects aim at completing the country's Cadastre, along with producing bases in standards that could be a foundation for Land Registry and Cadastre Information System (LRCIS). It is possible to produce cadastral data with today's technological means. In this context, three dimensional Cadastre data can be properly produced, especially in digital Cadastre projects with the required point accuracy. Nevertheless this is not enough for LRCIS. The Cadastre bases that have been produced so far by different methods with different scales and bases, with or without coordinates, should also be converted into digital form based on National Basic GPS Network of Turkey (NBGN) in required point-location accuracy. As the result of evaluation of graphical Cadastre bases produced without coordinates, actual land measurements, and information obtained from sheets and field book data together, it was found out that there are significant base problems in the graphical maps. These bases, comprising 20% of Turkey's Cadastre constitutes the most important bottleneck of completing the country's Cadastre. In the scope of this paper, the possibilities of converting the field book measurement values of graphic Cadastre bases into digital forms in national coordinate system by comparing them with actual land measurements are investigated, along with Turkey's Cadastre and its problems.

Cadastre 2014: New Challenges and Direction
2020Co-Authors: Anna Krelle, Abbas RajabifardAbstract:SUMMARY Land and land related activities form part of the basis of all economies and therefore the societies they support. Land is managed through land administration, with successful economies relying on effective land administration systems. At the core of land administration is the Cadastre. Cadastre 2014 is a strategic document published in 1998 by FIG that contains six core statements and a vision for future cadastral systems. However, many developments, issues and challenges have emerged since 1998, requiring that Cadastre 2014 be re-assessed in light of these, to ensure that its statements and vision align with current and future needs of society. This paper provides an analysis of the Cadastre‟s strategic statements against the current needs and challenges of society, offering recommendations for each statement. The aim is to contribute to Cadastre 2014 to ensure it most effectively supports cadastral systems of today and in the future.

3d digital Cadastre journey in victoria australia
ISPRS Annals of the Photogrammetry Remote Sensing and Spatial Information Sciences, 2017Co-Authors: Davood Shojaei, Hamed Olfat, Mark Briffa, Abbas RajabifardAbstract:Abstract. Land development processes today have an increasing demand to access three-dimensional (3D) spatial information. Complex land development may need to have a 3D model and require some functions which are only possible using 3D data. Accordingly, the Intergovernmental Committee on Surveying and Mapping (ICSM), as a national body in Australia provides leadership, coordination and standards for surveying, mapping and national datasets has developed the Cadastre 2034 strategy in 2014. This strategy has a vision to develop a cadastral system that enables people to readily and confidently identify the location and extent of all rights, restrictions and responsibilities related to land and real property. In 2014, the land authority in the state of Victoria, Australia, namely Land Use Victoria (LUV), has entered the challenging area of designing and implementing a 3D digital Cadastre focused on providing more efficient and effective services to the land and property industry. LUV has been following the ICSM 2034 strategy which requires developing various policies, standards, infrastructures, and tools. Over the past three years, LUV has mainly focused on investigating the technical aspect of a 3D digital Cadastre. This paper provides an overview of the 3D digital Cadastre investigation progress in Victoria and discusses the challenges that the team faced during this journey. It also addresses the future path to develop an integrated 3D digital Cadastre in Victoria.

Assessment of the Australian digital Cadastre protocol (ePlan) in terms of supporting 3D building subdivisions
Land Use Policy, 2016Co-Authors: Davood Shojaei, Hamed Olfat, Ashley Darvill, Abbas Rajabifard, Mark BriffaAbstract:Population growth and lack of available land in urban areas have resulted in intensive property development both above and below ground. According to the ‘Cadastre 2034 Strategy’ published by the Intergovernmental Committee on Surveying and Mapping (ICSM) for Australia in 2014, the current digital Cadastres have limitations in positional accuracy and do not adequately represent the three-dimensional nature of real property. This strategy highlights the fact that land parcels that are limited in vertical dimension are not adequately represented in the current digital Cadastre. This makes it difficult to visualise security of tenure as it relates to a building or an apartment within a building. Since 2011, a national cadastral data model (ePlan Protocol) is being implemented in different Australian jurisdictions including Victoria, New South Wales and Queensland for 2D (non-building) plans of subdivision. Following the ICSM’s strategy, the ePlan Working Group has started to investigate the requirements for supporting 3D building subdivisions in ePlan. As part of this investigation and to assess the potential of the ePlan Protocol in terms of supporting 3D spatial units associated with land and property management, a research project was recently undertaken in Victoria, Australia. In this research, various building subdivision plans were investigated and modelled in ePlan and a number of technical and non-technical challenges were identified. Overall, the study confirmed that the ePlan Protocol is able to support 3D building subdivision plans, however curved shapes are not well handled. This paper also proposes future investigations for implementing a 3D digital Cadastre in Victoria.

legal barriers to 3d Cadastre implementation what is the issue
Land Use Policy, 2013Co-Authors: Serene Ho, Abbas Rajabifard, J E Stoter, Mohsen KalantariAbstract:Abstract The ways society use and occupy space occur in multiple dimensions; however, the ways we manage and administer space relies on two-dimensional information representations (2D). The legal ambiguity and administrative limitations inherent in such practices are becoming increasingly pronounced within land administration especially for urban areas. In response, a research domain has emerged – termed by specialists as ‘3D Cadastres’ – to seek greater correspondence between the administration of legal land and property (parcel) boundaries and the reality of physical bounds of structures themselves. Within this corpus of literature, advances in the technical domain are evident. However, other areas of research have not experienced the same degree of attention, with a particular lag in analysis of legal issues: this apparently explains the lack of progress in the realisation of operational 3D Cadastres. However, given many countries actually already administer ownership of 3D property within current statutory frameworks, is the continued concentration on legal issues a red herring? Are legal issues significant barriers to implementation, and if not, what other considerations are there? This position paper, comprising two main sections, aims to consider, clarify and reconceptualise the significance of the law as an obstacle to implementation of 3D Cadastres. It does this by firstly reviewing the legal issues articulated within the literature and examining the extent of its impact using current practical examples. This leads to the conclusion that finding alternative methods and processes to overcome perceived legal issues actually facilitates progress towards 3D property registration and therefore, 3D Cadastre implementation. This challenges the dominant assumption that legal issues are a significant barrier. The paper then proposes to consider the influence of legal issues through an institutional lens, as a way of gaining other insights into how legal issues can influence 3D Cadastre implementation. The introduction of institutional theory and a theoretical framework provides a way to reconceptualise the role of legal issues in 3D Cadastre implementation. The framework is further used as a sensitising mechanism for discussing broad-based institutional issues that have as yet, not been given significant consideration in the literature. The paper concludes with a response to the main research question and the proposition that significant barriers to 3D Cadastre implementation lies not in technological or legal issues, but the more fundamental social and cultural issues that make up the institutional framework underpinning cadastral systems.

Expropriation in the Simple Cadastre
Nordic journal of surveying and real estate research, 2020Co-Authors: Gerhard Navratil, Andrew U FrankAbstract:In this paper we investigate the necessary interaction between expropriation and the Cadastre. We investigate first the role of expropriation in modern society and the stake holders and then analyze the interaction with land registration and Cadastre. The "simple Cadastre" framework allows a treatment independent of national particulars. A simple Cadastre is a minimal model that satisfies the needs of the users of the Cadastre and abstracts from non-essential aspects, any national legislation is full of. In this paper we investigate how a Cadastre supports expropriation and what the necessary interface is. We conclude that the expropriation procedures need access to registration data and a process to register a transfer of ownership effectuated by a court judgment, but no special arrangements that would only serve expropriation procedures.

the austrian land Cadastre from the earliest beginnings to the modern land information system
Geodetski Vestnik, 2014Co-Authors: Anka Lisec, Gerhard NavratilAbstract:The objective of this discussion is the Austrian land Cadastre, which forms the basis of the Austrian land information system, together with the land registry. From a data structure perspective, the Austrian land Cadastre is a traditional parcel-oriented system and includes a geometric description of land plots linked to other records describing the nature of the land plots. The changeable institutional (legal) framework was shaped the continuous development of the Austrian land Cadastre since the first systematic land survey and cadastral mapping at the beginning of the 19th century. With the progress of information technology in recent decades, it has been developed into a contemporary land information system, which (together with the land registry) provides up-to-date land information. It has to be emphasized that the current land Cadastre still contains some data from its very beginning and, for this reason, the historical development of this evidence, including data sources, is of great importance for users of these data. The first part of the article provides an introduction to the historical development of the Austrian land Cadastre, followed by the presentation of contents and procedures of the current land Cadastre.

Requirements of 3D Cadastres for height systems
Computers Environment and Urban Systems, 2013Co-Authors: Gerhard Navratil, Eva Maria UngerAbstract:Abstract Three-dimensional (3D) cadastral systems can only be built if there are suitable height reference systems. However, the earth is neither homogeneous nor flat, and the plumb lines are curved and not parallel. Thus, the definition of height and the implementation of geodetic height systems are complex. 3D Cadastres must connect to the existing national height reference. In addition, cadastral systems are designed to persist for centuries. Over such long periods, the earth changes, from plate tectonics, erosion, human intervention, etc. Changes in the technology of measurement equipment can also occur, allowing different definitions. These considerations are important in the design of a 3D Cadastre. At minimum, the height system used for the Cadastre must be well-defined, to enable adjustments from potential changes in the height system or even the actual point heights. This study examines existing height systems and the determination of height in the context of cadastral tasks. Accuracy requirements for height in a 3D Cadastre are analyzed using typical examples. The selected height system must support these requirements. This study also develops the questions that must be answered and highlights the problems that can emerge in some of the solutions. There is no height reference system that fits all needs, and each solution has advantages and disadvantages. Different systems may be optimal for different countries. It may also be beneficial to allow different geometrical qualities for different parts of a country.

processes in a Cadastre
Computers Environment and Urban Systems, 2004Co-Authors: Gerhard Navratil, Andrew U FrankAbstract:Abstract A Cadastre is a system of major importance for economy and planning. A Cadastre provides data on land. It is the basis for legal aspects like ownership as well as fiscal aspects like taxation of land. The Cadastre also provides data for planning assignments (for example, boundaries of constructions, land use, and soil). Storage and update of these data require a complex system that had been developed in Austria during more than 100 years. Understanding, using, and improving a Cadastre requires knowledge on the cadastral processes. The problems a Cadastre must solve are important to understand the needs for a Cadastre. It is also important to understand the processes of a Cadastre to see how a Cadastre works. These processes define the way a Cadastre handles data and what prerequisites the data must fulfil to be accepted by the Cadastre. Improving a system requires analysis of the processes. The user wants to work with a Cadastre. He needs processes that meet his demands. Improving the efficiency of the processes, therefore, improves the efficiency of the Cadastre directly because then the user will be satisfied (his work will be done better or faster). The paper discusses the tasks of a Cadastre. The starting point is the needs of users (owners, government and many others). The needs define the tasks and the data needed to fulfil the tasks. The next step is the definition of the processes to fulfil the tasks. The paper then formalizes these processes. Finally, implementations for two different cadastral systems prove the general validity of the processes.

The requirements for point Cadastres
2020Co-Authors: R. Antwi, Rohan Bennett, W T De Vries, Christiaan Lemmen, C. MeijerAbstract:SUMMARY This paper reintroduces the point Cadastre: a cadas tal system where geographic points are used to represent land parcels. When point features are combined with satellite imagery, freely available topographic maps (e.g. OpenStreetMap), and managed using cloud based geographic information services, a simple cadastral solution becomes apparent. This paper concentrates only on defining requirements for poin t Cadastres. Three discrete studies were used to generate the requirements: expert group mee tings, a pressure cooker meeting, and an online questionnaire. The requirements are classifi ed under preparation, functional, quality, and architectural categories. Preparation requireme nts illustrate the need for contextual awareness before commencing any point cadastral project. Functional requirements are found to be similar to the requirements of parcel based c adastres, however, the necessity for parcel boundary identification is removed. Quality require ments promoted the need for ‘ease of use’ and ‘low cost’. Architectural requirements provided various options for collecting, storing, maintaining, and visualizing the cadastral point in formation. Together, the requirements provided deliver a basic blueprint for land adminis trators considering point Cadastre solutions. This is a significantly shortened version of a pape r submitted to an academic journal.

neo Cadastres innovative solution for land users without state based land rights or just reflections of institutional isomorphism
Survey Review, 2015Co-Authors: W T De Vries, Rohan Bennett, J A ZevenbergenAbstract:AbstractIn many countries, authority for maintaining records of land ownership lies with national or state institutes, called ‘Cadastres’ or ‘land registries’. The emergence of volunteered geographic information (VGI) and crowdsourcing potentially challenges this state based authority, enabling the construction of ‘neo’-Cadastres (using the analogy of ‘neo’geography). Individual citizens can themselves map and record land tenure rights. This paper explores if and how VGI and crowdsourcing may redefine the state based Cadastres and land registries, and the roles of land users who claim land rights outside of the state based institutions. Using theories of institutions and isomorphism we hypothesise that a parallel exists between emerging open systems and situations where no state-based Cadastre exists: participants in both situations will position themselves to protect their interests. Three cases from Ghana, Canada, and Indonesia demonstrate how land users indicate their land tenure right boundaries based...

The point Cadastre requirement revisited
Survey Review, 2013Co-Authors: R Hackman-antwi, Rohan Bennett, W T De Vries, Christiaan Lemmen, C.

Utilising data modelling to understand the structure of 3D Cadastres
Journal of Spatial Science, 2013Co-Authors: Ali Aien, Abbas Rajabifard, Mohsen Kalantari, Ian Williamson, Rohan BennettAbstract:No jurisdiction currently maintains a fully functioning 3D Cadastre. Lack of legal support, guidelines, and available technologies for acquiring and visualising 3D cadastral objects provide reasons. Additionally, the scope of 3D Cadastres is wide and ambiguous with no firm agreement on the necessity and structure of 3D Cadastres. Without a clear scope and vision, implementation of 3D Cadastres is difficult. This paper builds from this premise. It is argued that developing a 3D cadastral data model is an effective methodology to identify and understand the scope and nature of 3D Cadastres. This paper proposes a 3D cadastral data model (3DCDM). The 3DCDM provides a practical framework to model layered legal objects of survey plans and their physical counterparts using architectural and engineering plans. The data model is based on the requirements of 3D Cadastre and it provides a resilient starting point for developing a 3D cadastral database.
