Development of an Integrated BIM-3D GIS Approach for 3D Cadastre in Morocco

Abstract

With rapid population growth, there is an increasing demand for vertical use of space. The wide spread of complex and high-rise buildings, as well as the increasing number of infrastructure above or underground, requires new methods for efficient management of land property. 3D cadastre has, thus, become a necessity for land administration. However, the success of 3D cadastral systems relies on the definition of legal and institutional frameworks and requires implementing performant technical solutions. The potential of BIM and 3D GIS in this field has been demonstrated by several authors. However, cadastral development is strongly related to the national context of each country in terms of laws, institutions, etc. In this paper, an integrated approach based on BIM and 3D GIS for the implementation of a 3D cadastre in Morocco is presented. This approach demonstrates the relevance of such integration for the efficient management of cadastral information. First, a Conceptual Data Model (CDM) based on an extension of CityGML, was proposed for the management of cadastral information in Morocco. Then, a BIM modeling process was developed according to the model’s specifications and then translated to CityGML format. After that, a 3D Geodatabase was implemented in ArcGIS based on the proposed CDM. Our method was applied to a case of co-ownership building, showing several difficulties and limits in terms of 2D representation. The results show several advantages in terms of representation and management of 3D cadastral objects. In addition, some improvements are proposed to extend the concept of co-owner share to a volumetric calculation.

“…However, interlinking these standards requires addressing geometric conversion and semantic interoperability (Atazadeh et al, 2017b;Saeidian et al, 2021). For example, some studies worked on the interoperability between LandInfra and LADM (Kalogianni et al, 2021;Lemmen et al, 2021;Stubkjaer et al, 2018), the integration of IFC and LADM (Oldfield et al, 2017;Ramlakhan et al, 2023), CityGML and LADM (Góźdź et al, 2014;Gürsoy Sürmeneli et al, 2022;Li et al, 2016), CityGML and IFC (Hajji et al, 2021;Rashidan et al, 2021), and LADM, IFC, and CityGML (Mi, 2019;Sun et al, 2019) in the land administration domain. In addition, jurisdictions may be reluctant to use more than one data model to store, manage, and communicate all data components since this would potentially increase the cost and time for buying, establishing, and training data models.…”

“…3D models can be divided into two applications: applications based on visualization and those not based on visualization [10]. Examples of applications using a 3D model are noise propagation analysis in an area [11,12], 3D cadaster [13], facility management [14], solar radiation estimation analysis [15], energy demand estimation in an area [16], and urban water demand [17].…”

Cross-sectional SWOT Analysis of BIM and GIS Integration

“…It seems that an equally great opportunity, and something that may in some time be crucial for a correct real estate management policy, is the 3D cadaster. Concepts of how such systems could work are already described in the literature, among others in [75][76][77]. Undoubtedly, one of the components of such systems, in addition to descriptive, administrative, or legal data, would be data related to the building (for example, based on IFC to CityGML conversion), the object environment (strictly GIS data) or infrastructure.…”
