Property valuation is a process that promotes sustainable development as it supports and forms several land management activities. Access to information on the legal, geometric, physical, locational and environmental characteristics of property units together with the economic indicators are required for an effective property valuation system. Traditional cadastral systems generally provide only two-dimensional (2D) legal and geometric information about property units, however, today’s valuation practices would benefit significantly from three-dimensional (3D) information in order better to estimate and explain values of property units. The purpose of this paper is to examine how 3D spatial datasets and spatial analyses have been used in property valuation, and to develop 3D valuation unit profile(s) in line with the examination results for the recently proposed Valuation Information Model that extends the ISO 19152:2012 Land Administration Domain Model (LADM) from the valuation point of view. The study focuses more on 3D locational and environmental characteristics of property units; particularly visibility and especially viewshed analysis in terms of property valuation. By using open topography, building and height datasets of the Netherlands, a number of viewshed analyses are conducted to show how it can be utilized using different 3D data sources. The main contribution of the article is to present how 3D datasets and spatial analyses could be used to support property valuation activities and to investigate to what extent it is possible and meaningful to include derived 3D characteristics of property units in valuation registries.  相似文献

China's economic reforms over the past decades have given rise to the development of a rudimentary urban land market. Although one cannot speak of a land “market” in the strict sense of the word, there is an urban land allocation system in which land lease rights can be acquired through the payment of a land-use fee. If the urban land market is to develop in a sustainable manner, new credible institutions need to be established that can safeguard greater legal security and transparency. For these purposes, it is necessary to establish a management system that can support the legal (tenure security), economic (leases, taxes) and broader aspects (spatial and environmental land use policies) of land administration. To make an urban land administration system socially credible and functional, land-related information should be registered and structured at a detailed spatial level, such as parcels. There is no parcel-based information system in China, but the country has developed a population registration system at a detailed spatial level that could be a starting point to develop integrated information systems, or a so-called “local spatial data infrastructure”. This paper reviews China's population registration system and their spatial units and presents a proposal for an information system that can be expanded or adapted to meet the requirements of an effective land administration system.  相似文献

The Organisation of Eastern Caribbean States (OECS) was assisted by the Australian government's aid agency, AusAID, with technical input from UNHabitat and the University of the West Indies, St. Augustine, in the developing of regional land policy guidelines that will address the most critical land issues being faced by the countries. A key aspect of this project was to evaluate pro-poor land tools that would provide comprehensive land administration and thus facilitate the equitable use and allocation of the limited land resource in the sub-region. This initiative provided for and included an opportunity for introducing the Social Tenure Domain Model (STDM) to support economic, social or environmental land policy goals. The individual member states of the OECS committed to participate in the project notwithstanding existing institutional shortcomings that may affect implementation.This paper reviews the major characteristics in land administration shared by most of the OECS countries that will affect the implementation of the STDM which is based on the LADM international standard ISO 19152:2012. It then presents a proposed STDM profile that will address the land issues common to most of the OECS states. Lastly, it presents the preliminary results of pilot testing of an implementation of the STDM, software version 0.9.5, developed by the Global Land Tool Network (GLTN). The pilot was conducted in Saint Lucia, and St. Vincent and the Grenadines. The primary aim was to examine the practical and social implications of implementing the recording process for informal tenures using the STDM software developed by the GLTN. It was found that some of the technical process went smoothly but middle and lower middle income groups are resistant to the idea of recognising informality because they perceive difficulties in differentiating between legitimate land tenure rights and illegal occupation and use, and because they anticipate impacts on their own legal tenure.  相似文献

The protection of agricultural land and forests is a relatively new concept in Poland, and it began with forest protection in the 1920s. The first regulations on the protection of agricultural land were introduced only in the 1960s. Agricultural land and forests received comprehensive protection pursuant to the provisions of the Act of 26 October 1977 on the protection of agricultural land, forests and land recultivation. This legal act set the foundations for the protection of farmland and forests in successive decades.The aim of this study was to determine the influence of farmland and forest protection on spatial planning and to highlight the loss of agricultural and forest land resulting from conversion to other purposes. Legal regulations pertaining to spatial planning and the protection of agricultural and land forests were analysed. The scale of the problem was identified, and future land-use types were forecast based on the data developed by Statistics Poland (GUS). The existing spatial plans (municipal master plan - MMP) were analysed to determine the conversion loss index (CLI) associated with the conversion of agricultural land and forests to other uses. Legal regulations pertaining to the protection of agricultural land and forests were also analysed, and the extent of the relevant conversion measures was determined. The study demonstrated that urban development and the inevitable urbanization of rural areas contribute to the loss of agricultural and forest land that are converted to other uses.  相似文献

This paper explores the selection and implementation of planning strategies and land use instruments for dealing with population decline in three different regions in the Netherlands. The study shows that each region developed very specific responses that can be explained by the different discourses that dominated planning and policymaking in that region. Although the perceptions about population decline, its consequences and suitable responses are strongly context specific, in all three regions responsible governments deemed it necessary to adapt existing policies and plans and to tailor strategies to a situation with population decline. The study also shows that ideas about using planning as a tool to stimulate economic growth prevail in the studied regions, but that it are precisely these ideas that hamper the development and implementation of policies for dealing with population decline. The paper also illustrates how Evolutionary Governance Theory can be useful for explaining why regions take different routes in dealing with population decline and for analysing the different dependencies that influence the selection of strategies.  相似文献

The relationships of regional integration, land tenure and land use have all received substantial previous attention. Nonetheless, existing theoretical frameworks tend to presume ideal types of land tenure in understanding the impacts of regional integration on change in institutions and land use. We therefore evaluate the evolutionary theory of land rights (ETLR) for the case of Madre de Dios, Peru. This is a useful case since tenure for agricultural lands is private individual as the ETLR theorizes, but other characteristics, such as the presence of forest extractivism, depart from the assumptions of the ETLR. We pursue a multi-step analysis of key relationships of the ETLR, focusing particularly on the linkages between highway paving as an indicator of regional integration, titling as a measure of tenure formality, multiple indicators of land market engagement, and land uses with diverse ramifications for ecological sustainability. Findings for the different steps partially support the ETLR for the case of Madre de Dios. Disconfirmation however sometimes occurs due to geographic accidents rather than due to truly contrasting findings. We conclude by discussing the need to identify characteristics of empirical cases that do and do not fit the expectations of theories in order to better evaluate the applicability of theory for analysis and policy.  相似文献

The focus of coastal management in recent years has shifted from a sectoral plan to a holistic and integrated one. A key component of this integrated plan is spatial planning. This paper serves to highlight the role of spatial planning in coastal management by making use of a study done for the Tuticorin coast in India. A quantification of the land use/land cover changes in this region was studied along with the existing laws and policies governing the Indian coast with particular reference to Tuticorin, to determine their influence/impact on coastal land use/land cover. The results of the study show the disparity that exists between current land use practices and the laws that have been enforced to safeguard the coast. This can be overcome by means of implementing a more stable management plan that incorporates the spatial aspects of this coast, which has been presented.  相似文献

Sustainable spatial planning has become increasingly important during the last decades. Politics tries to counter land use related challenges such as urban sprawl by the implementation of policy measures. In a direct democracy, the implementation of policy measures requires citizens’ acceptance. This paper examines determinants of voters’ policy measure acceptance in the area of spatial planning. The study analyses 18 popular votes on spatial planning measures between 1984 and 2008 in Switzerland. A Bayesian multilevel modelling method is used to estimate both determinants at the individual level as well as the contextual level. Results show that the main individual factor for voters in Switzerland to accept spatial planning measures in a broad sense are the party affiliations of voters. Another important factor for the voting decision is being a homeowner. In contrast, whether voters live in urban or rural areas does not influence such voting decisions. At the contextual level, policy measures which contain incentive and market-based instruments have a higher probability to be accepted than bans and rules. Moreover, the degree of organisational capacity and conflict capability of interests concerned seem to influence democratic acceptance of spatial planning measures.  相似文献

Scenarios are accepted as useful tools for assessing economic and environmental impacts of land use changes, for involving stakeholders in environmental issues and thus for decision-making. In most studies involving comparison and evaluation of scenarios, a reference situation from which different scenarios will be developed is defined. When dealing with rural areas, scenarios, and thus reference situation, should not only consider land use but also cropping systems. The usual lack of data concerning cropping system distribution in a given region can be overcome by the use of expert knowledge. In this paper, we present a procedure for the spatial allocation of cropping systems that integrates expert knowledge and quantitative data. The aim of this procedure is to develop a reference situation that makes explicit the link between cropping systems and the factors responsible for their geographical location (location factors).  相似文献

Many nations lack a coherent national approach to land administration. Instead, land information and processes are frequently disaggregated across states, provinces, cantons, counties, or municipalities. This is particularly the case in federated countries. The growing body of land administration theory often assumes or prescribes the need for national systems; however, the justification for this approach requires further explanation. Without justification, nations that maintain disaggregated systems lack the impetus to unlock the opportunities veiled within their disparate land administration systems. Moreover, a nation's ability to respond effectively to emerging national and global-scale issues such as climate-change is greatly impeded. This paper aims to explain the need for national land administration infrastructures. Qualitative case studies of the Australian context and the method of triangulation inform the justification. The research reveals most drivers can be classified into six overarching subsets: adherence to international standards by national governments, better federal or central governance, improved shared governance, scale of economies for lower levels of government, opportunities and savings for business, and social inclusion for citizens. Unfortunately, specific drivers are found to be complex and changeable, as political, scientific and environmental debates raise policy issues: there is no single solution. As an alternative, nations must seize on the specific drivers relevant to their context. They must employ them to transform disparate land administration systems into multi-purpose national land administration infrastructures that deliver benefits to all stakeholder groups.  相似文献

This paper explores the case of peripheral settlement growth in the Greater Frankfurt (Main) region within current debates on global suburbanization. Within Germany’s sophisticated spatial planning regime, Greater Frankfurt’s system of regionalized land-use planning marks an ambitious initiative to contain urban sprawl. Nonetheless, expansive peripheral settlement growth, and socio-spatial polarization remain distinct characteristics of the booming region. Analyzing state regulation vis-à-vis dynamics of capitalist urbanization and private authoritarianism, we decipher the complex governance arrangements producing this, at first sight, contradictory simultaneity. We uncover the rationales of local growth politics of autonomous municipalities and the region’s multiplied institutional fragmentation that undermine planning ambitions to contain suburban growth. We conclude by critically assessing the political economies of suburbanization in Greater Frankfurt and point to prospects for regional reform.  相似文献

In a context where several sectors of society compete for space, land use types must be carefully designed and spatially allocated to guarantee a sufficient level of relevant ecosystem services (ES) in a territory of interest. In this respect, contemporary land use planning involves multiple, often conflicting objectives and criteria. Consequently, major benefits can be expected from spatial decision support systems (sDSS) designed to deal with complex spatial allocation problems.This paper presents the generic conceptual framework ‘OSMOSE’ and its free and open source software implementation, for the generation of specific sDSSs for spatial land use planning. The specific sDSSs generated with OSMOSE are meant to (i) identify land units which meet multiple predefined ES-attribute values for a specific land use type (LUT) and (ii) rank land units for a given LUT according to these multiple ES-attributes. A complementary purpose is to (i) identify and (ii) rank LUTs for a given land unit. Whereas ‘identification’ is done by means of a threshold query, ‘ranking’ is based on the Iterative Ideal Point Thresholding (IIPT) method. The proposed framework is extremely flexible as it can accommodate differentially weighted, continuous and/or ordinal attributes with, for the latter, equal or unequal number of classes, alternative land unit definitions and land use types. Moreover, assessments cannot only be made using ES-levels for the land unit/LUT combinations but also in terms of changes in ES-levels after a particular change of LUT.The OSMOSE framework is illustrated by means of the specific sDSS BoLa which is generated to support land use planning in the region of Flanders (Belgium) with focus on soil protection. Four cases are presented in which the decision support varies between the available approaches (threshold – selection, threshold – ranking, IIPT – selection, IIPT – ranking).  相似文献

The development of 3D property registration systems is indispensable for the spatial determination of property Rights, Restrictions and Responsibilities (RRR), the sustainable operation of property markets and the safeguarding of ownership in the highly urbanized world. Several developments in computer graphics, 3D modelling and rendering techniques have attracted the growing global interest in 3D cadastre. Since 2012, the Land Administration Domain Model (LADM ISO 19152) is adopted as the international standard for 2D and 3D cadastral data modelling. Developed legal procedures and prototype systems for 3D property rights registration provide interesting solutions for data acquisition and visualization but such approaches are time and cost demanding. In parallel, 2D cadastral surveying procedures have progressed significantly in reducing required time and cost, utilizing crowdsourcing methodology and mobile services.This paper presents a technical solution under development, aiming to provide the beginning for a new era in the initial acquisition, registration and representation of 3D crowdsourced cadastral data, appropriate for both the developed and the developing world. The proposed solution consists of two complementary parts, the technical framework and the crowdsourced methodology to be followed. The technical framework consists of two interconnected parts, the server-side and the client-side. The server-side refers to the Database Management System (DBMS) where the collected data are stored. The client-side refers to the data capturing tool, which in this case is the mobile device. For the server-side, a prototype system based on model driven architecture practices and LADM is developed; while for the client-side, an open-source mobile application for the acquisition of 3D crowdsourced cadastral data, 3D modelling and visualization of 3D property units as block models (LoD1) on a mobile’s phone screen in real-time, is developed.This research is focused on investigating technical aspects for capturing and integrating data about legal rights on physical objects. Detailed investigation of legal issues is not within the objectives of this research. Two case-studies for testing the proposed technical solution are made. An assessment of the current stage of development of the technical solution is presented. The main conclusions converge that the proposed technical solution has huge potentials for the fast, economic implementation of 3D cadastral surveys as it can produce an accurate and reliable 3D information model, depending on the accuracy of the available basemaps. The developed application is easy-to-use as users may not have the necessary level of 3D modelling skills in order to contribute to the registration procedure.  相似文献

This paper reviews a number of conceptual issues pertaining to the implementation of an explicit “spatial” perspective in applied econometrics. It provides an overview of the motivation for including spatial effects in regression models, both from a theory‐driven as well as from a data‐driven perspective. Considerable attention is paid to the inferential framework necessary to carry out estimation and testing and the different assumptions, constraints and implications embedded in the various specifications available in the literature. The review combines insights from the traditional spatial econometrics literature as well as from geostatistics, biostatistics and medical image analysis.  相似文献
