Integrating CityGML and LADM for 3D Building Management - Taking Taiwan as an Example

The recent advances of surveying and mapping technology has made the collection of 3D information increasingly easier. A variety of real-world phenomena nowadays can be modelled in a realistic way, which enables the development of many innovated applications (Liu Wei Zhe, 2020). Due to the rapid expansion of urban population and limited land...

Towards Investigation of Integrating LADM, BIM, and CityGML of 3D Condominium Rights for Cadastral Purposes: The Case of Turkish Cadastral System

Four basic concepts form the basis of a modern land management system: Land Tenure, Land Value, Land Use, and Land Development. Cadastral studies are seen as the cornerstone of these four basic concepts. Especially, complex buildings located underground and above ground form the basis of 3D cadastral studies. In addition, international research...

Evaluation of the International 3D Geospatial Data Models and IFC Standard for Implementing an LADM-based 3D Digital Cadastre

Land Administration Domain Model (LADM) is an international standard for defining both semantic and spatial information connected with rights, restrictions, and responsibilities (RRRs) that affect land, water, built assets, natural resources, underground spaces, and airspaces. Since LADM is currently a conceptual land administration model, one...

Revising Surveying and Representation Package of LADM Profile for Serbia to Support 3D Spatial Information

LADM profile for Serbia was developed by Radulović et al. (2017) reflecting the current state of Serbian cadastral information system which is based on 2D spatial information. It also provides general discussion of the need for establishing 3D cadastre in Serbia without specific details about its possible implementations and developments. Given...

Integration of LADM and CityGML for 3D Cadastre of Turkey

Representation of Right, Restriction, and Responsibility (RRR) in the 2D cadastral system falls short due to rapid urbanization causing complex infrastructures. Turkish cadastre, as in many other countries, faces difficulties in the daily recording of property transactions such as sales, donations among others. Therefore, it is highly...

Converting BIM Data to CityGML for 3D Cadastre Purposes

Currently, stratified property rights are registered and managed using two-dimensional subdivision plans. These plans do not accurately depict property spaces in complex structures such as high-rise buildings, tunnels and utilities, underground infrastructures, etc. 3D rich data like building information modelling (BIM) could be utilized as a...

Contextualising Ontologies with Image, Number and Rationality

Ontologies have been proven useful in areas such as information management and Artificial Intelligence. Based on ontologies, datasets using the same concepts can be integrated or converted automatically. The same concept however can represent different features depending upon perspectives. A concept “building” for instance can represent a...

Semantics-based Fusion for CityGML and 3D LandXML

For any developments that require spatial data, often the fusion of diverse spatial datasets is unavoidable. For instance in developing a 3D cadastral database serving various purposes, data may need to be sourced from different spatial datasets such as: building design models in BIM (Building Information Model) format, topographic and built...

The Possibilities of Using CityGML for 3D Representation of Buildings in the Cadastre

The main objective of the paper is to elaborate the possibilities of applying CityGML for cadastral purposes, drawing particular attention to the three-dimensional representation of buildings. Technical realization of the issue is executed at the conceptual level by integration the Land Administration Domain Model, officially published as an...

Integration of Land Administration Domain Model with CityGML for 3D Cadastre

As our urban environments are densifying, it is essential to extend traditional cadastral systems that are based on two dimensional representation of ownership to support 3D. With the need to define property ownership in vertical as well as horizontal dimensions becoming pertinent around the world, a practical solution to represent 3D cadastral...

The Conversion from CityGML to 3D Property Units

Due to the fast growth of building construction technology and increasing demands on the efficient use of land, human living space are expanded from on the surface to above and under the earth surface. It raises the need for three dimentional (3D) cadastral by realizing that the current cadastral system based on 2D is not appropriate to reflect...

Semantically Rich 3D Building and Cadastral Models for Valuation

Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces)....

A cityGML 3D geodatabase for building's energy efficiency

This paper illustrates the results of a research focused on the development of a multi-scale geodatabase designed to store the data needed to measure the energy buildings performance of buildings to be used for the planning activities of local administrations. Due to the great complexity of the application domain, the proposed data model has...
