[Termes IGN] urbanismeRésumé : (auteur) Geographical data and analysis are a key asset in different domains of education, from primary school to high education and life-long learning, and of research like geography, history, urbanism or environmental science, among others. Engaging with these user communities is part of the mission of many EuroSDR members. It is also a precious investment to improve data value and reusability. Firstly, the education community can give relevant feedback on the data usability from their pedagogical perspectives, scientific users can comment on quality documentation as they need to adopt a critical perspective on results obtained with data and students learn to use such complex data before they go into the work force where they may promote their usage. Second, all these users can help data providers investigate the design of new products to answer emerging needs. Three commission chairs of EuroSDR (Commission 4 Information usage, Commission 5 Business models and operations and Commission 6 Knowledge transfer) launched a survey on the provision of data and tools for research and education purposes on 13th May 2019. The objective of the survey was to study existing initiatives in terms of practices and projects at EuroSDR organizations to provide data and tools to pupils, students, teachers, and scientists for research and/or education purposes. A questionnaire was sent to all the delegates of EuroSDR who represent national mapping and cadastral agencies (NMCAs). The respondents were asked to describe their potential initiatives by using a standardized template format, which is in the Annexe 1 of this report. The respondents could describe as many initiatives as relevant for the provision of their data and tools. The deadline was set for 1st July 2019. The answers were compiled and reported in a first draft. As the answer rate was rather low, the draft report was circulated in Spring 2020 again. The first section of this report presents an overview of the results obtained from this survey and the next section presents them more in details using the same structure as the questions of the template.

[Termes IGN] système de gestion de connaissancesRésumé : (auteur This article presents a conceptual model of sport events legacy based on the Olympic and Paralympic Games as a reference. The legacy of mega sport events has gained ever more importance during recent years for both academics and practitioners. The International Olympic Committee looked at the concept of legacy, as it is the best argument with which to illustrate the lasting benefits that are derived from the Olympic Games. The Legacy is the way to structure the capitalization of the benefits and lessons related to the organization of major sporting events. So, our motivation is to develop a tool of the sport events legacy. The aims of the article are first, to investigate the legacy sport events literature, second, to propose a Legacy Conceptual Model (LCM) and to transpose it to a database which will be support to analyse the changes related to legacy. This research target also has a practical implication. So, we investigate how the LCM helps to analyze the legacy left by a sport eve nt using a case study.

[Termes IGN] télémétrie laser terrestreRésumé : (auteur) Monitoring of man-made structures and regions posing potential natural hazards plays a pivotal role in preventing human and economic losses and thus, has been a central topic in geodesy for a long time. However, while the monitored objects (e.g. landslides) often are areal phenomena, classic geodetic monitoring still applies point-based measurement systems. Over the past few years, area-based methods (e.g. terrestrial laser scanning) are closing this gap and allow the acquisition of object geometry or surfaces with high spatial resolution and high accuracy. However, with the use of terrestrial laser scanning (TLS) for monitoring, new challenges arise. Two examples of such challenges are the scan registration and the mitigation of time-varying artefacts. When TLS is used for monitoring, scans over a sequence of epochs have to be acquired. The different scans have to be transformed into a common stable reference frame before changes between epochs can be analysed. This process is called registration and well-established solutions exist for scanning at close-range or scenes without changes between the scans. However, the standard approaches are not applicable for scenes with significant deformations and observed from long-range, a scenario typically encountered in the monitoring of natural hazards. Thus, in such monitoring cases, the need for other approaches exists. Furthermore, when scanning over long ranges, time-varying artefacts affect the resulting point clouds. These artefacts can be caused e.g. by atmospheric refraction and may result in apparent displacements of up to a few decimetres. Due to the temporarily and spatially varying air density distribution during the time required for the individual scan acquisition, the resulting point clouds are distorted systematically, but non-linearly. To tackle these two challenges, a data-driven registration algorithm for scan pairs of scenes with significant changes between epochs and an investigation of the time-varying artifacts are presented. The core of the registration approach is a data-driven classification of the scene into stable and unstable areas and a registration based on the stable areas only. The proposed registration algorithm is successfully applied to two different scenarios (an indoor and an outdoor scene). For both scenarios, the algorithm performs well with a sensibly chosen set of parameters. In addition, the algorithm is successfully applied to scans from an experimental study carried out in the scope of the investigation of the time-varying artefacts. This investigation focuses on atmospheric refraction and is based on numerical simulation and an experimental study, that allows a clear detection and analysis of the atmospheric effects. The numerical simulation demonstrates that these effects can cause apparent displacements on a decimeter-level, resulting from a combination of the measurement ray curvature and the terrain inclination. The results are corroborated by the experimental study. Additionally, the data from the experiment show that the magnitude of the effects from atmospheric refraction varies with time of the day. Currently, there is no solution to a data-driven or forward-modeling based compensation available but the study herein indicates that the effects might be mostly negligible when using only scans acquired at certain times in the evening.

[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.
