Cartographie et géomatique avec R (2024)

Deux modules R principaux servent aujourd’hui pour le traitement de données géomatiques: Pour comprendre ces modules R en détail, je vous recommande l’excellente documentation de Timothée Giraud & Hugues Pecout. Le présent exercice vise à vous familiariser avec les éléments de base de la cartographie vectorielle avec R. Le prérequis pour comprendre les instructions ci-dessous […]

Railway Track Gauge: a Material Substrate of Nostalgia and Defiance

A look at the global map of rail track gauges immediately reminds you of the current invasion of Ukraine. There is a material substrate of the putinist nostalgia of the Muscovite Empire.

The impossible territory and the maps of the boyar Kraiensky

Figure 1 Overlapping territories of First Nations in the perception of their members. Screenshot from the geomatics site https://native-land.ca/ . Unstable borders are a cartographer’s nightmare. The simple task of reporting on demographic changes quickly becomes a headache in a country whose municipalities merge, divide, and even change their spatial contours according to the projects […]

Text2Landscape: Visualize a Text in Multiple Spaces with R — Force-directed networks, Biofabric, Word Embeddings, Principal Component Analysis and Self-Organizing Maps

You will find no realistic landscapes prior to the Renaissance. The saints of medieval murals float in a conceptual space informed by hierarchies and symbolic relations; so do those of the Prajñāpāramitā Sūtras. The word “landscape” appears with the Dutch painters of the 15th century. A landscape is a part of the world perceived by […]
