3D Web Services for Visualization and Data Sharing in 3D Cadastre

Abstract

Land has an essential role in any society, either as one of the most important capitals of mankind or as a place for people's life and activities. Therefore, registration of ownership and land use rights in a formal system is a major issue. In different countries, Cadastre systems can register extent, rights, restrictions and responsibilities related to land parcels. Many organizations such as municipality, tax and banks need to this information for planning and decision making. Considering the needs for land information by different organizations, access to cadastre data gains a lot of importance. Despite this importance, access to cadastre information encounter with different challenges such as differences in platforms or data structures and access to semantic and geometric data. The main goal of this research is to overcome these challenges and to improve the interoperability in sharing and accessing 3D cadastre data and challenges. This paper investigates capabilities of current 3D Spatial Web Services: WFS, WVS, WTS and W3DS as well as advantages of using these 3D services for access to 3D cadastre data. The authors also combined the legal classes of LADM with geometrical classes of CityGML for transferring the semantic and geometric cadastre data. Finally, some prospects of using 3D Web Services will be illustrated through implementation the scenarios. The most important advantages of using 3D Spatial Web Services in cadastre are on the fly construction and on demand presentation of 3D cadastral model, facilitating of access to legal and descriptive cadastre information, no necessity to user's awareness of data structure in cadastre database and compatibility with different levels of users.

Object Analysis and 3D Spatial Modelling for Uniform Natural Resources in China

“…The LADM focuses on the areas of land administration that are mainly connected to real properties, land ownership and the geometrical (spatial) components of natural resources [31]. This model provides a framework to extend property models to fit different administrative systems.…”

Web Based 3d Visualisation of Time-Varying Air Quality Information

“…The authors provided a visualisation using 3D buildings to show the calculated energy demand of each building. Zardiny and Hakimpour (2015) indicated that 3D Spatial Web Services allow on the fly construction and on demand presentation of the 3D cadastral models via Web.3D representations of city objects, which can be populated from 2D, or 3D vector models. 3D representations of city objects can also be generated (reconstructed) using images.…”
