[Termes IGN] trace GPSRésumé : (auteur) Crowdsourced traces collected by GPS devices during sports activities are now widely available on different websites. The goal of this paper is to study the potential of crowdsourced traces coming from GPS devices to highlight updates in authoritative geographic data. To reach this goal, an approach based on two steps is proposed. First, a data matching method is applied to match authoritative data and crowdsourced traces. Second, for the non-matched crowdsourced segments composing a trace, different criteria are defined to decide if whether or not, non-matched segments should be considered as an alert for update in authoritative data. The proposed approach is tested on crowdsourced traces and on BDTOPO® authoritative road and path network in mountain area. The results are promising: 727, 1 km of missing paths were found in the test area, which corresponds to 7.7% of the total length of used traces. The discovered missing paths also represent a contribution of 2.4% of the total length of BDTopo® road and path network in the test area.

[Termes IGN] SIG 3DRésumé : (auteur) Since renewable energy sources are in increasing demand due to the energy transition, the planning of new (Power) Transmission Line (TL) is becoming more and more important. Conflicting interests between stakeholders, the legislation and different transmission technologies turn TL planning into a complex spatial decision problem, however. Therefore, a Spatial Decision Support System (SDSS) which combines Multi-Criteria Decision Analysis (MCDA) techniques with methods provided by Geographic Information Systems (GIS) can support decision-makers in finding an optimal Transmission Line Path (TLP) that suits different interests. Existing SDSS, however, are constrained to either overhead lines or earth cables, while no computational solution has been found so far, for how they can be combined with each other. Furthermore, the methods prevailingly used come with some conceptual issues that affect realistic TL planning. Therefore, we investigated several methods for making GIS-based TL planning more realistic, developing two approaches that are the first of their kind to identify an optimal corridor for a combined line (CL), based on two different decision models. Both approaches were included in a 3D Decision Support System (3D DSS), which consists of various algorithms for determining optimal TL corridors and paths on different voltage levels, regardless of the transmission technology. A user study conducted with nine experts revealed that the procedural approach was most supported and represented stakeholders’ interests most reliably when identifying optimal CLs. Our results provide evidence that the 3D DSS facilitates the planning of new TLs, fosters the profound analysis of different alternatives, and supports stakeholders when discussing the benefits and weaknesses of different TLP alternatives. Since experts have high confidence in benefiting from a computer-based semi-automated approach, SDSS will play an increasingly important role in future TL planning.

[Termes IGN] ville intelligenteRésumé : (éditeur) This book covers a range of topics including selective technologies and algorithms that can potentially contribute to developing an intelligent environment and smarter cities. While the connectivity and efficiency of smart cities is important, the analysis of the impact of construction development and large projects in the city is crucial to decision and policy makers, before the project is approved. This book also presents an agenda for future investigations to address the need for advanced tools such as mobile scanners, Geospatial Artificial Intelligence, Unmanned Aerial Vehicles, Geospatial Augmented Reality apps, Light Detection, and Ranging in smart cities. Some of selected specific tools presented in this book are as a simulator for improving the smart parking practices by modelling drivers with activity plans, a bike optimization algorithm to increase the efficiency of bike stations, an agent-based model simulation of human mobility with the use of mobile phone datasets. In addition, this book describes the use of numerical methods to match the network demand and supply of bicycles, investigate the distribution of railways using different indicators, presents a novel algorithm of direction-aware continuous moving K-nearest neighbor queries in road networks, and presents an efficient staged evacuation planning algorithm for multi-exit buildings.
