[Termes IGN] service fondé sur la positionRésumé : (auteur) Indoor maps lay the foundation for most indoor location-based services (LBS). Building Information Modeling (BIM) data contains multiple dimensional computer-aided design information. Some studies have utilized BIM data to automatically extract 3D indoor maps. A complete 3D indoor map consists of both floor-level maps and cross-floor paths. Currently, the floor-level indoor maps are mainly either grid-based maps or topological maps, and the cross-floor path generation schemes are not adaptive to building elements with irregular 3D shapes. To address these issues, this study proposes a novel scheme to extract an accurate 3D indoor map with any shape using BIM data. Firstly, this study extracts grid-based maps from BIM data and generates the topological maps directly through the grid-based maps using image thinning. A novel hybrid indoor map, termed Grid-Topological map, is then formed by the grid-based maps and topological maps jointly. Secondly, this study obtains the cross-floor paths from cross-floor building elements by a four-step process, namely X-Z projection, boundary extraction, X-Z topological path generation, and path-BIM intersection. Finally, experiments on eight typical types of cross-floor building elements and three multi-floor real-world buildings were conducted to prove the effectiveness of the proposed scheme, the average accuracy rates of the evaluated paths are higher than 88%. This study will advance the 3D indoor maps generation and inspire the application of indoor maps in indoor LBS, indoor robots, and 3D geographic information systems.

occupation of many infrastructures for water, storm-water, sewer, electricity, gas, etc. Urban and ecological problems can be faced thanks to them. However, they are difficult to manage because of the impossibility of seeing them. The location of existing infrastructures is a necessity for controlling their development. Converting from CAD to GIS may improve the CAD drawings with spatial information and attributes and allows a better accessibility, accuracy and performance [Warner, 2013]. The Geographic Information System (GIS) implementation process for municipalities can be very complex, expensive, and time consuming, depending on the knowledge of municipalities. Maps of underground infrastructure systems are mainly stored in paper or CAD format and many cities and organizations around the world are putting significant efforts into converting those maps into GIS format. However, most of these efforts are uncoordinated and a formal protocol is missing to deal with GIS map update and version control. During this internship, it was asked to survey current practices in the world and develop a formal protocol to convert and manage GIS maps of underground infrastructure systems. The project required a technical expertise (to account for the potentials and limits of GIS) and specific knowledge about underground infrastructure systems. I had to survey current efforts in the world to convert and manage underground maps mainly thanks to a survey of municipalities and through online searches. Then developed a formal protocol illustrated by a general flowchart that should offer a streamlined strategy to ensure effective conversion from CAD to GIS and allows a better data management. The project resulted in a scientific publication. These works allowed me to develop GIS, Python, communication and writing skills in English.Note de contenu : Introduction

[Termes IGN] modélisation 3D du bâti BIMRésumé : (auteur) [introduction] For decades, computer-aided design (CAD) and geographic information systems (GIS) have been like oil and water. CAD users, who see their work as engineering-based, focus on very accurate measurements and high-precision placement. They view GIS as neither accurate nor precise. GIS users, who see their work as larger scale and more cartographic in nature, cannot achieve the same accuracy over large geographies. While CAD is mostly about points and lines, GIS is also about polygons, imagery, and colors used to convey large amounts of information. While both have attributes and layers, users treat them and store them differently. In recent years, building information modeling (BIM) has emerged as a third parallel universe in the architecture, engineering, and construction (AEC) sector.
