Géomatique et cartographie avec R Pour la réalisation de traitements reproductibles de l’information géographique. Le logiciel R permet depuis longtemps de traiter les données spatiales, plusieurs packages forment un socle permettant la mise en œuvre de ces traitements. Les développements actuels s’appuient sur ce socle et forment un écosystème robuste qui offre aux utilisateurs la plupart des fonctionnalités autrefois réservées aux Systèmes d’Information Géographique, et cela dans un environnement favorable à la reproductibilité des résultats de recherche. Ce manuel est destiné tant aux utilisateurs de R souhaitant mettre en place des traitements de données spatiales qu’aux utilisateurs souhaitant utiliser R pour réaliser les tâches qu’ils réalisent habituellement avec un SIG. R package logos for osrm and valh package Map of the Lot department in France. The map has an inset for a municipality in the topleft corner. A map showing roads that intesersect a specific municipality.

We just published a JOSIS paper on what spatial data science languages have in common and what they still need. Insights from across the R, Python & Julia ecosystems.

New version of {maplegend} ! 📦
{maplegend} is an R package for creating, well, map legends. 🙂
This version improves the display of legends in plots and introduces two new features: a histogram legend type, and arguments to set decimal and big value separators […]
