[Termes IGN] système d'information géographiqueRésumé : (auteur) The convergence of research on landscape and heritage holds great strategic potential for establishing novel connections between the heritage resources of a territory. This text reflects on the ability of the landscape to situate inherited assets within a framework of spatial coherence in relation to the peri-urban spaces of large cities, heritage areas of great historical depth that have been particularly aggressively exposed to the urban development dynamics of the second half of the twentieth century. In order to address these often forgotten spaces, this text presents a system for heritage management argued from the standpoint of and towards the landscape and based on historical interpretation, cartographic analysis, mapping and digital documentation. Geographic technologies and graphic expression are basic pillars to integrate historical information with the language and resources of the disciplines involved in landscape planning and design, advancing criteria for a forward-looking landscape-based heritage management.

[Termes IGN] Wuhan (Chine)Résumé : (auteur) Metro accessibility has attracted interest in sustainable transport analyses. Hence, the accuracy of metro-accessibility measures have become increasingly vital. Various spatiotemporal factors, including by-metro accessibility, land-use accessibility and to-metro accessibility, affect metro accessibility; however, measuring metro accessibility while considering all these components simultaneously is challenging. By integrating these factors into a unified analysis framework, this study aims to strengthen the method for metro-accessibility assessment. Specifically, we proposed the “By metro–Land use–To metro” model to conduct a metro-accessibility index and develop an accessibility-based station typology. The results show that Wuhan metro system accessibility presented a “high-medium-low” spatial disparity from the urban center to the periphery. Meanwhile, the variety of metro-accessibility characteristics and typologies in Wuhan will equip urban planners and policymakers with a useful tool for better organising by-metro accessibility, land-use accessibility and to-metro accessibility.

[Termes IGN] vision par ordinateurRésumé : (auteur) Mobile mapping, in particular, Mobile Lidar Scanning (MLS) is increasingly widespread to monitor and map urban scenes at city scale with unprecedented resolution and accuracy. The resulting point cloud sampling of the scene geometry can be meshed in order to create a continuous representation for different applications: visualization, simu- lation, navigation, etc. Because of the highly dynamic nature of these urban scenes, long term mapping should rely on frequent map updates. A trivial solution is to simply replace old data with newer data each time a new acquisition is made. However it has two drawbacks: 1) the old data may be of higher quality (resolution, precision) than the new and 2) the coverage of the scene might be different in various acquisitions, including varying occlusions. In this paper, we propose a fully automatic pipeline to address these two issues by formulating the problem of merging meshes with different quality, coverage and acquisition time. Our method is based on a combined distance and visibility based change detection, a time series analysis to assess the sustainability of changes, a mesh mosaicking based on a global boolean optimization and finally a stitching of the resulting mesh pieces boundaries with triangle strips. Finally, our method is demonstrated on Robotcar and Stereopolis datasets.

Ces documents historiques fournissent des informations inestimables pour analyser des transformations spatiales complexes sur des périodes importantes. Cela est particulièrement vrai pour les zones urbaines qui englobent de multiples domaines de recherche imbriqués : humanités, sciences sociales, etc. La complexité des cartes (texte, bruit, artefacts de numérisation, etc.) a entravé la capacité à proposer des approches de vectorisation polyvalentes et efficaces pendant des décennies. Dans cette thèse, nous proposons une solution apprenable, reproductible et réutilisable pour la transformation automatique de cartes raster en objets vectoriels (îlots, rues, rivières), en nous focalisant sur le problème d'extraction de formes closes. Notre approche s'appuie sur la complémentarité des réseaux de neurones convolutifs qui excellent dans et de la morphologie mathématique, qui présente de solides garanties au regard de l'extraction de formes closes tout en étant très sensible au bruit. Afin d'améliorer la robustesse au bruit des filtres convolutifs, nous comparons plusieurs fonctions de coût visant spécifiquement à préserver les propriétés topologiques des résultats, et en proposons de nouvelles. À cette fin, nous introduisons également un nouveau type de couche convolutive (CConv) exploitant le contraste des images, pour explorer les possibilités de telles améliorations à l'aide de transformations architecturales des réseaux. Finalement, nous comparons les différentes approches et architectures qui peuvent être utilisées pour implémenter chaque étape de notre chaîne de traitements, et comment combiner ces dernières de la meilleure façon possible. Grâce à une chaîne de traitement fonctionnelle, nous proposons une nouvelle procédure d'alignement d'images de plans historiques, et commençons à tirer profit de la redondance des données extraites dans des images similaires pour propager des annotations, améliorer la qualité de la vectorisation, et éventuellement détecter des cas d'évolution en vue d'analyse thématique, ou encore l'estimation automatique de la qualité de la vectorisation. Afin d'évaluer la performance des méthodes mentionnées précédemment, nous avons publié un nouveau jeu de données composé d'images de plans historiques annotées. C'est le premier jeu de données en libre accès dédié à la vectorisation de plans historiques. Nous espérons qu'au travers de nos publications, et de la diffusion ouverte et publique de nos résultats, sources et jeux de données, cette recherche pourra être utile à un large éventail d'applications liées aux cartes historiques.

[Termes IGN] santé des forêtsRésumé : (auteur) Spatially explicit information on the distribution of dominant tree species groups and aboveground biomass (AGB) in forested areas is essential for developing targeted forest management and biodiversity conservation measures, as well as assessing forest carbon sequestration capacity. There is a shortage of continuously updated 30-m spatial resolution products for mapping dominant tree species groups. The vast majority of remote sensing-based AGB estimation approaches have relatively low accuracy for dominant tree species groups or forest types and are unsuitable for AGB modeling. Therefore, this study aims to develop an integrated framework that considers the phenological characteristics of different tree species to improve the mapping accuracies of forest dominant tree groups and corresponding AGB estimates. Thirty-meter resolution maps of dominant tree species groups were created using machine learning algorithms and phenological parameters. Features extracted from optical and radar images and phenological characteristics were used to construct AGB estimation models in a temporally consistent manner to improve the AGB estimation accuracy and perform dynamic AGB monitoring. The proposed method accurately characterized the dynamic distribution of the dominant tree species groups in the study area. The traditional AGB model that does not consider different forest types or species had an R2 value of 0.52, whereas the proposed model that considers phenology and forest types had an R2 value of 0.67. This result indicates that incorporating information on phenology and dominant species improves the accuracy of AGB estimations. The AGB in most regions was 30–55 t/ha, showing that the majority of the forests were young or middle-aged stands, and the areal percentage of AGB greater than 30 t/ha increased during the study period, suggesting an improvement in forest quality. Furthermore, the oak AGB was the highest, indicating that oak afforestation should be encouraged to enhance the carbon sequestration capacity of future forest ecosystems. The results provide new insights for researchers and managers to understand the trends of forest development and forest health, as well as technical information and a database for formulating more rational forest management strategies.
