[Termes IGN] semis de pointsRésumé : (auteur) Pine wilt disease is one of the most destructive disease of pine forests. It is important to detect and exterminate infected trees for preservation of the forest. We demonstrated a novel method combining individual tree detection (ITD) and classification by logistic regression using unmanned aerial vehicle (UAV) images for the mapping of infected trees. In the ITD phase, 50 % and 84 % of damaged trees were automatically detected from the 3D point cloud generated from the UAV images using the local maximum filter. These rates of detection were comparable to previous studies that used UAV imagery. Subsequently, five vegetation indices calculated from multispectral and visible color (RGB) images were used. Among the vegetation indices, normalized difference vegetation index (NDVI), normalized difference red edge index (NDRE), and vegetation atmospherically resistant index (VARI) were preferable explanatory variable in the logistic regression to divide damaged and undamaged trees. The accuracy of these models ranged from 98 % to 100 % and the F-measure ranged from 94 % to 100 %. The best model, the logistic regression model using VARI as the explanatory variable, was then tested using five datasets to evaluate general performance. Each model showed explicitly high accuracy ranging from 95 % to 100 %. The best accuracy when considering the ITD and classification was 84 %. To map pine wilt disease, the proposed method is suitable for practical use due to its high-efficient and low-cost.

[Termes IGN] personne non-voyanteRésumé : (auteur) Visually impaired people cannot use classical maps but can learn to use tactile relief maps. These tactile maps are crucial at school to learn geography and history as well as the other students. They are produced manually by professional transcriptors in a very long and costly process. A platform able to generate tactile maps from maps scanned from geography textbooks could be extremely useful to these transcriptors, to fasten their production. As a first step towards such a platform, this paper proposes a method to infer the scale and the content of the map from its image. We used convolutional neural networks trained with a few hundred maps from French geography textbooks, and the results show promising results to infer labels about the content of the map (e.g. "there are roads, cities and administrative boundaries"), and to infer the extent of the map (e.g. a map of France or of Europe).

[Termes IGN] rédaction cartographiqueRésumé : (éditeur) The book comprises four sections. Section 1 introduces the SDGs and their relation to geospatial data, describing SDG indicators and data transformations for mapping. Section 2 describes foundational design decisions in the cartographic workflow including projections, scale, generalization, symbolization, typography, and visual hierarchy among others. Section 3 introduces common map types (e.g., choropleth maps, proportional symbol maps, dasymetric maps, bivariate maps, cartograms) and diagrams (e.g., bar charts, scatterplots, timelines) for representing the SDG indicators. Finally, Section 4 discusses considerations for map use environments such as audiences, user interfaces and interaction operators, mobile and web media, storytelling versus exploration, and open access.

[Termes IGN] seizième siècleRésumé : (éditeur) This open access book presents the first detailed study of one of the most important masterpieces of Renaissance cartography, Martin Waldseemüller’s Carta marina of 1516. By transcribing, translating into English, and detailing the sources of all of the descriptive texts on the map, as well as the sources of many of the images, the book makes the map available to scholars in a wholly unprecedented way. In addition, the book provides revealing insights into how Waldseemüller went about making the map (information that can’t be found in any other source). The Carta marina is the result of Waldseemüller’s radical re-evaluation of what a world map should be; he essentially started from scratch when he created it, rejecting the Ptolemaic model and other sources he had used in creating his 1507 map, and added more descriptive texts and a wealth of illustrations. Given its content, the book offers an essential reference work not only on this map, but also for anyone working in sixteenth-century European cartography.

[Termes IGN] réseau de transportRésumé : (auteur) This thesis deals with the modelling of historical accessibility values, covering Switzerland and neighbouring regions from today until 1720. Changes in transport supply have spatial e ects on environment, society and economy; many of them are persistent. There are methods to quantify, isolate and capture causality. However, related studies are rarely done, one reason for that being missing data. The thesis details methods to reconstruct historical transport networks and corresponding travel system times. The related techniques, relevant conditions in historical transport maps and procedures needed are explained in detail. The associated numbers related to development in transport and travelling are prepared. The thesis shows applications of such results regarding state reach and productivity gains. The accessibility model includes both transport on the main road network as well as the space in-between capturing all relevant transport modes and generating continuous results for long-distance travel. Results show strong border e ects; this might be due to the population distribution model or the rather flat weight function. Results show an increase of accessibility over time, following the networks available at the time and along the central axes.
