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.

Barriers to achieving the benefits of BIM / Heikki Halttula in International journal of 3-D information modeling, vol 4 n° 4 (October - December 2015)  

Public [article]  inInternational journal of 3-D information modeling > vol 4 n° 4 (October - December 2015) . - pp 16 - 33 Titre : Barriers to achieving the benefits of BIM Type de document : Article/Communication Auteurs : Heikki Halttula, Auteur ; Harri Haapasalo, Auteur ; Maila Herva, Auteur Année de publication : 2015 Article en page(s) : pp 16 - 33 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications photogrammétriques [Termes IGN] architecture [Termes IGN] Finlande [Termes IGN] implémentation (informatique) [Termes IGN] lasergrammétrie [Termes IGN] modélisation 3D du bâti BIM Résumé : (Auteur) The purpose of this paper is to study the benefits of building information modelling (BIM) and determine the barriers to achieving these benefits. The use of BIM is not yet at a level where known benefits can be realised. This study consists of a literature review of the benefits of BIM and an empirical review, where focus group interviews were used to discover barriers. The major benefits of BIM include cost savings, better information flow, shorter project timelines and better quality. The greatest barrier is the lack of practical guidelines for BIM implementation in projects. Successful BIM implementation requires technology, people and processes to be in proper shape. Earlier studies identify the theoretical requirements of BIM implementation, but practical solutions are still not at an adequate level.

A historical timber frame model for diagnosis and documentation before building restoration / Mathieu Koehl in International journal of 3-D information modeling, vol 4 n° 4 (October - December 2015)  

Public [article]  inInternational journal of 3-D information modeling > vol 4 n° 4 (October - December 2015) . - pp 34 - 63 Titre : A historical timber frame model for diagnosis and documentation before building restoration Type de document : Article/Communication Auteurs : Mathieu Koehl, Auteur ; Anthony Viale, Auteur ; Sophie Reeb, Auteur Année de publication : 2015 Article en page(s) : pp 34 - 63 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Applications SIG [Termes IGN] Bas-Rhin (67) [Termes IGN] bien immobilier [Termes IGN] diagnostic [Termes IGN] données lidar [Termes IGN] données localisées 3D [Termes IGN] image terrestre [Termes IGN] levé topographique [Termes IGN] maquette numérique [Termes IGN] patrimoine archéologique [Termes IGN] restauration de bâtiment [Termes IGN] seizième siècle [Termes IGN] SIG 3D [Termes IGN] système d'information géographique [Termes IGN] système d'information historique Résumé : (Auteur) The aim of the project that is described in this paper was to define a four-level timber frame survey mode of a historical building: the so-called “Andlau's Seigniory”, Alsace, France. This historical building was built in the late XVIth century and was in a stage of renovation in order to become a heritage interpretation centre. The used measurement methods combine Total Station measurements, Photogrammetry and 3D Terrestrial Laser scanner. Different modelling workflows were tested and compared according to the data acquisition method, but also according to the characteristics of the reconstructed model in terms of accuracy and level of detail. 3D geometric modelling of the entire structure was performed including modelling the degree of detail adapted to the needs. The described 3D timber framework exists now in different versions, from a theoretical and geometrical one up to a very detailed one, in which measurements and evaluation of deformation by time are potentially allowed. The virtually generated models involving archaeologists, architects, historians and specialists in historical crafts, are intended to be used during the four stages of the project: (i) knowledge of the current state of needs for diagnosis and understanding of former construction techniques; (ii) preparation and evaluation of restoration steps; (iii) knowledge and documentation concerning the archaeological object; (iv) transmission and dissemination of knowledge through the implementation of museum animations. Among the generated models one can also find a documentation of the site in the form of virtual tours created from panoramic photographs before and during the restoration works. Finally, the timber framework model was structured and integrated into a 3D GIS, where the association of descriptive and complementary digital documents was possible. Both offer tools leading to the diagnosis, the understanding of the structure, knowledge dissemination, documentation and the creation of educational activities. The integration of these measurements in a historical information system will lead to the creation of an interactive model and the creation of a digital visual display unit for consultation. It will be offered to any public to understand interactively the art of constructing a Renaissance structure, with detailed photos, descriptive texts and graphics. The 3D digital model of the framework will be used directly in the interpretation path, within the space dedicated to “Seigniory” of Andlau. An interactive touch-screen will be installed. It will incorporate several levels of playgrounds (playful, evocative and teaching). In a virtual way, it will deal with the different stages of building a wooden framework and clarify the art of construction.

Integrating space, time, version, and scale using Alexandrov topologies / Norbert Paul in International journal of 3-D information modeling, vol 4 n° 4 (October - December 2015)  

Public [article]  inInternational journal of 3-D information modeling > vol 4 n° 4 (October - December 2015) . - pp 64 - 85 Titre : Integrating space, time, version, and scale using Alexandrov topologies Type de document : Article/Communication Auteurs : Norbert Paul, Auteur ; Patrick Erik Bradley, Auteur Année de publication : 2015 Article en page(s) : pp 64 - 85 Note générale : Bibliographie Langues : Anglais (eng) Descripteur : [Vedettes matières IGN] Bases de données localisées [Termes IGN] données 4D [Termes IGN] données spatiotemporelles [Termes IGN] échelle cartographique [Termes IGN] intégration de données [Termes IGN] modèle relationnel [Termes IGN] niveau de détail [Termes IGN] topologie d'Alexandroff Résumé : (Auteur) This article introduces a novel approach to higher dimensional spatial database design. Instead of extending the canonical Solid–Face–Edge–Vertex schema of topological data, these classes are replaced altogether by a common type SpatialEntity, and the individual “bounded-by” relations between two consecutive classes are replaced by one separate binary relation BoundedBy on SpatialEntity which defines a so-called Alexandrov topology on SpatialEntity and thus exposes mathematical principles of spatial data design. This has important consequences: First, a mathematical definition of topological “dimension” for spatial data can be given. Second, every topology for data of arbitrary dimension has such a simple representation. Also, version histories have a canonical Alexandrov topology, and generalizations can be consistently modeled by continuous foreign keys between LoDs. The result is a relational database schema for spatial data of dimension 6 and more which seamlessly integrates 4D space-time, levels of details and version history. Topological constructions enable queries across these different aspects.
