3D Zoning: A Missing Piece to Link Planning Regulations with 3D Cadastre

Interpreting planning regulations could be a challenging task for land surveyors when defining new ownership boundaries and for responsible authorities (e.g., city council) when assessing proposed developments. They need to be aware of the impacts of planning regulations on land parcels and vice versa since these regulations contain legally...

How to quickly detect the overlap and the consistency between LADM with LandInfra and LandXML: Application of schema matching techniques

In this paper, we explore the schema matching techniques to compare the content of three geospatial standards which are LADM, LandInfra (InfraGML) and LandXML. Those standards all refer to the concept of “land” and we will try to quantify the similarity of them based on syntax and semantic comparison of the class names exposed in their...

3D Cadastre Visualization: Recent Progress and Future Directions

The 3D Cadastre has been investigated from many viewpoints (including legal, organizational and technical). However, to date little research has focused specifically on visualizationrelated aspects despite the value-added of the third dimension. The paper first proposes an overview of progress made in the last five years in 3D cadastral...

3D Cadastre: With or Without Subsurface Utility Network?

Within the global trend of designing and implementing 3D cadastre, this paper offers a discussion about the integration of subsurface utility networks in such land tenure systems. Three questions are addressed: Do we need to register underground objects? Should underground networks be registered in the Land Register, with the same specifications...

Terrestrial LiDAR Capabilities for 3D Data Acquisition (Indoor and Outdoor) in the Context of Cadastral Modelling: A Comparative Analysis for Apartment Units

The paper presents a comparison of terrestrial LiDAR and Distancemeter for surveying 3D spatial data of property units (indoor and outdoor) and producing cadastral representations (2D and 3D). Two study sites representing apartment buildings (co-ownership units) were surveyed with both instruments and six criteria related to data acquisition...

Visualization, Distribution and Delivery of 3D Parcels: Position Paper 4

This paper is the second of two position papers that serve as the basis for discussion in a forum held at the 4th International on 3D Cadastres, 9-11 November 2014, Dubai, UAE. The first paper was published in 2011 (Pouliot, 2011). The overall objective of the FIG Working Group discussion is to provide feedback to the FIG Commission 3 (Spatial...

Visualization Principles in 3D Cadastre: A First Assessment of Visual Variables

This paper proposes to investigate which among visual variables are more appropriate (if they are) for geo-visualization of 3D legal units in a probable 3D cadastre system. Visual variables, as proposed by Bertin (1983), include position, size, shape, value, color, orientation and texture. The appropriateness is evaluated base on whether a...

Spatial Representation of Condominium/Co-ownership: Comparison of Quebec and French Cadastral System based on LADM Specifications

In order to progress towards a better cadastral management system that integrates the 3rd dimension the paper compares the situation of the 3D representation of vertical divided co-ownership between Quebec and French jurisdictions. Some part of the comparison analysis is made based upon the land administration data model (LADM) specifications....
