Cartographie et géomatique avec R (2023)

Deux modules R principaux servent aujourd’hui pour le traitement de données géomatiques:

le module sf (simple features) dédié aux géodonnées de type vecteur, qui rassemble les développements antérieurs réalisés notamment dans les modules sp, rgdal et rgeos.

Le module terra, dédié aux géodonnées de type raster.

Pour comprendre ces modules R en détail, je vous recommande l’excellente documentation de Timothée Giraud […] Continue Reading…

Railway Track Gauge: a Material Substrate of Nostalgia and Defiance

Railway track gauge. Source:

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. Far more than a purported linguistic or cultural proximity of the ex-Soviet states, this substrate of steel paves the way for geopolitical […] Continue Reading…

The Man from the Future: The Visionary Life of John Von Neumann — a Foreword

I’ve had the pleasure to write a foreword of the French translation of Ananyo Bhattacharya’s biography of John von Neumann, translated by Anatole Muchnik and now published by Quanto.

You can read the French introduction and have a peek at the book’s first chapter (PDF).

In agreement with Ananyo, here is the English translation.

As you read the biography of […] Continue Reading…

You can see the conference in French on the CERN Globe webpage.

Tonight, I propose to talk about two ideas, two concepts. The first one you already know: the concept of utopia. The other […] Continue Reading…

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 .

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 of their inhabitants and councillors, […] Continue Reading…

Écrire l’espace (2022)

Ce cours-atelier introduit à l’espace et à ses figurations comme outil de création et d’expression littéraires

Les écrivaines recourent aux cartes de territoires physiques et imaginaires pour poser leur récit. Les fouilleurs de texte (text miners) utilisent des figurations spatiales pour étudier de vastes corpus. Il existe de nombreux types d’espaces: l’espace topographique de la géographie physique, de l’urbanisme et […] Continue Reading…

The Bifurcation as a View of the Mind

Let us assume the existence of A and B, two points connected by a straight line which, if it extends beyond B, lets us imagine C, a point located anywhere on this imaginary line. C, then, can be said “in the continuity” of A and B. We’ll arrive at point C if we do not deviate. C will happen […] Continue Reading…

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 a human being at […] Continue Reading…

Execute SPARQL chunks in R Markdown

Coding in R is useless without interesting research questions; and even the best questions remain unanswered without data. RStudio provides a number of convenient ways to acces data, among which the possibility to write SQL code chunks in Rmarkdown, to run these chunks and to assign the value of the query result directly to a variable of your choice. […] Continue Reading…
