Abstract

With the existence of mature technologies and modern urban planning necessities, there is a growing public demand to improve the efficiency and transparency of government administrations. This includes the formation of a comprehensive modern spatial land management (cadastre) system having the capacity to handle various types of data in a uniform way—above-terrain and below-terrain—enabling the utilization of land and space for various complex entities. To utilize existing knowledge and systems, an adaptive approach suggests extending and augmenting the existing 2D cadastre systems to facilitate 3D land management capabilities. Following a comprehensive examination of the Survey of Israel’s operative cadastral system that supports 2D land administration, it turned out that it is crucial to outline new concepts, modify existing terms and define specification guidelines. That is, to augment and provide full 3D support to the current operative cadastral system, and to create a common and uniform language for the various parties involved in the preparation of 2D and 3D mutation plans required for modern urban planning needs. This study refers to the legal and technical aspects of Survey of Israel’s CHANIT, which is the legal set of cadastral work processes specifications, focusing on database, data structure, functionality, and regulation gaps while emphasizing on 3D cadastral processes. The outcome is recommendations concerning data structure and functionalities needed to be addressed for the facilitation and implementation of an operative 3D land management system in Israel.

Highlights

A 3D cadastral information system is the framework for defining and understanding the spatial restrictions, responsibilities, and rights related to spatial land arrangements
According to Aien et al [1], the information model should allow the understanding of the various parts in the three-dimensional cadastre, explain how they are arranged, organized and conserved using computerized systems, and simplify data understanding required by all parties involved. 3D cadastral systems should support the implementation of spatial cadastre processes, including (1) The promotion of spatial standards used by the involved parties; (2) The establishment of 3D databases and facilitation of processes and functionalities concerned with data dissemination; (3) The interoperable exchange, combine and share of datasets; (4) The provision of management functionalities required for the establishment of 3D cadastre data, ensuring the integrity and legitimacy of geometry, topology, and semantics
The methodology to formalize this approach is set in accordance with the recommendations made by Survey Of Israel (SOI), which structure the implementation of legislation related to 3D volumetric parcels, together with the review of SOI’s “CHANIT” specification; recommendations that will set new methods are made, related to processes, functions, and data

Summary

Introduction

A 3D cadastral information system is the framework for defining and understanding the spatial restrictions, responsibilities, and rights related to spatial land arrangements. According to Aien et al [1], the information model should allow the understanding of the various parts in the three-dimensional cadastre (geometries, classes, and attributes), explain how they are arranged, organized and conserved using computerized systems (instances of classes and constraints), and simplify data understanding required by all parties involved. Establishing a 3D cadastral information system is a direct response to the increasing public demand aimed at improving the existing efficiency and transparency of government administrations, required today to manage the ever-growing complex modern urban planning necessities. This paper addresses and suggests the definition of an appropriate topology for spatial parcels and the implementation of 3D cadastral workflows, ensuring that the data-structure and datasets defined for both 2D and 3D representations in the land management system are compatible with the existing spatial reality
