针对我国不动产传统登记中的二维表达、房地分离的管理模式,在综合分析产权体的定义基础上,提出三维地籍产权体的定义和对象类型,并从概念层次引入一种基于语义的多层次三维地籍产权体模型。该模型能综合考虑土地和房产管理模式,将产权体划分为街坊、三维宗地、三维地籍物、分层空间与单元空间5个空间管理细节层次,探讨根据产权体的权属情况划分产权体层次的过程,并通过语义详细描述每个层次产权体的空间关系、权属关系和几何实体拓扑关系。基于以上的理论和方法,选取了某片区地籍数据作为试验数据,实现了多层次三维地籍产权体模型的语义表达,从而明晰了不动产产权三维登记,为"房地合一"地籍管理模式进一步深化了技术基础。  相似文献

针对现有三维数据模型难以有效支撑三维不动产物理空间和产权空间一体化管理的问题,该文提出了顾及物理空间的三维不动产数据模型。基于土地管理领域模型(LADM)分析设计了产权语义类,并利用城市地理标记语言(CityGML)发展了多层级物理空间的构建方法,通过CityGML的扩展机制实现了产权空间要素类和物理空间要素类的语义关联以及一体化存储。实验表明,该模型能够有效表达“地—楼—层—户—间”多层次的几何语义信息,解决了三维不动产数据模型内容单一、缺乏建筑语义等难点,为不动产立体化产权管理和三维确权登记等工作提供了方法支撑。  相似文献

随着高层建筑物增多,多权属建筑物的三维地籍模型成为许多学者的研究热点。三维地籍是一种引入三维产权的领域模型,它除了登记和洞悉二维宗地的权属状况,还可以注册、明晰和界定三维产权单元的空间权属。据此,重点研究了应用SketchUp构建多层建筑物的立体模型,构建了三维地籍属性信息数据库,将三维模型和属性信息导入ArcGIS中,完成了多权属高层建筑物三维地籍模型构建和属性信息查询。  相似文献

根据现有三维数据模型和地籍数据特点,在分析实体(E)和四面体格网(TEN)的基础上,对三维地籍实体信息组织进行研究,提出了基于实体-四面体格网模型(E-TEN模型)的三维地籍数据模型,其核心思想是实体作整体结构,TEN做局部结构。在数据结构中,通过特定方式(特殊属性值CX)将二者结合在一起。该模型能够实现地籍实体对几何、属性等综合信息的一体化组织,有利于实现复杂三维地籍实体三维空间数据的有效组织与管理。  相似文献

地籍管理是土地管理的基础,是国家依法管理土地权属、保护土地所有者和使用者合法权益而采取的行政措施。本文针对当前地籍管理中二维宗地图常因界址不明而引发土地纠纷的现状,在城镇地籍管理中引入了表达直观的三维城市模型。三维空间的交互浏览、界址点、界址线与三维城市模型的叠加、宗地信息的查询以及三维宗地图的制图输出改变了传统地籍管理的模式,在实践中取得了较好的效果,是未来城镇地籍管理的一种重要手段。  相似文献

Three-dimensional (3D) land development and utilization has become the trend for urban planning in the current metropolis.This paper presents a method for building a 3D cadastral management system from survey plans with SketchUp.It concentrates on the geometric representation and topological consistent maintenance of 3D cadastral objects.In this system a complete topological model is built to express the body construction and spatial relationships among 3D property units.SketchUp is used to automatically construct 3D models with attributes and thematic information from 2D survey plans.Spatial topologic relationships and operations are analyzed with the programming and development of Ruby language.The resulting system can manage 3D cadastral objects and manipulate them with spatial operations to support spatial analysis.  相似文献

Cadastral surveying plays an important role in defining legal boundaries of land and property. The current practice for recording cadastral survey data mainly relies on 2D digital or analog documents. This practice is efficient for simple land parcels but can be challenged in complex building developments. To address the issues stemmed from 2D methods of representing cadastral survey data, 3D spatial information models can be considered as a viable solution for managing cadastral survey data. Building Information Modeling (BIM) enables colsslaborative 3D management of the design, construction, and operation of buildings. There have been extensive studies conducted to investigate the connectivity between BIM and 3D cadaster. Most of these studies focus on managing legal information, such as ownership boundaries and attributes, in BIM-based environments. However, there is limited investigation on how survey- ing measurements can be mapped into BIM. In this study, the proposed method for integrating the cadastral survey data into the BIM environment includes identifying cadastral survey requirements, using BIM entities relevant to cadastral survey data, enrichment of a BIM proto- type, and evaluation of the prototype. The major contribution of this study is to demonstrate the storage of cadastral survey data such as survey marks and traverse lines in the BIM environment. Therefore, this research contributes to the further enrichment of BIM with incorporating data elements related to cadastral surveying practices. It is confirmed that current BIM-based tools provide restricted capabilities for explicit management and visualiza- tion of cadastral survey data. This limitation can be addressed in the future enhancements of BIM in terms of supporting important elements for cadastral survey data.  相似文献

It is generally acknowledged that immovable property taxes are one of the main revenue sources for local government. The literature emphasizes that the administration of property taxes needs well-developed inventories or registers that provide complete and accurate records of the taxed properties and their legal-economic attributes. This requirement is generally fulfilled by Spatial Data Infrastructures (SDIs) in which the coordinate exchange and sharing of geo-spatial data is provided by separate registers/information systems such as: cadastral systems, building and address registers. Recently, the Open Geospatial Consortium presented a core component of a 3D SDI in the form of an international domain standard for representing, storing and exchanging 3D city models. The CityGML allows the semantic and 3D geometrical representation of physical objects but does not deal with the legal and administrative aspects of the city objects which are required for the process of property taxation. This paper outlines the development of an Application Domain Extension (ADE) for the immovable property taxation domain that expands the CityGML data model with the legal and administrative concepts defined in Turkish Law. The study shows that this ADE could be a 3D national data model for municipal information systems and facilitate a more efficient taxation process, as well as providing data for urban planning, facility management and other municipal services.  相似文献

地籍调查是以权属调查为核心,查清每一宗土地的位置、权属界线、数量、用途等基本状况,满足土地登记需要。地籍调查是土地登记的前期工作和法定程序之一。地籍调查按调查对象分为城镇地籍调查和农村地籍调查。目前农村地籍调查是在土地利用现状调查过程中同步完成的。农村地籍调查的主要成果是权属界线协议书、集体(国有)土地权属调查表(以下简称“一书一表”)。本文针对“一书一表”自动生成,探讨一种数据采集组织方法,以供参考。  相似文献

In underground environments, survey elements such as survey points and observations provide the information required to define legal boundaries. These elements are also used to connect underground legal spaces to a geodetic survey network. Due to the issues of current 2D approaches for managing underground cadastral data, prominent 3D data models have been extended to support underground land administration. However, previous studies mostly focused on defining underground legal spaces and boundaries, with less emphasis on survey elements. This research aims to extend CityGML to support underground cadastral survey data. The proposed extension is based on the survey elements elicited from underground cadastral plans, which is then implemented for an underground case study area in Melbourne, Australia. This extension integrates underground survey data with legal and physical data in a 3D digital environment and provides an improved representation of survey elements, facilitating the management and communication of underground cadastral survey data.  相似文献
