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. — Géomatique et cartographie avec R Pour la réalisation de traitements reproductibles de l’information géographique.

Esri proudly state on their website that they support DHS operations. The same agency that is currently doing door-to-door searches and murdering people in Minnesota. Another reason that UK and European governments need to ditch US global tech companies for open-source solutions

Some of the potential readers are ESRI products (that's not me, but final users).

Can ArcGIS Web or Pro read an online COG file (using the URL) as QGIS does?
I mean in real time, not downloading the full file.

Hi #OGC (or anybody who knows the answer).

Is there any OGC API that works with a COG?(Cloud Optimized GeoTIFF)

in https://ogcapi.ogc.org/#standards I see OGC Tiles (similar to WMTS) and OGC Maps (similar to WMS), but no way to use a simple COG.

I know I can make a service to provide WMTS reading a COG, but I want to avoid that service. I want to work directly with the GeoTIFF file(s).

Thanks.

Apple built the most powerful browser-based open source GIS without even intending it. I forked their Embedding-Atlas, added @maplibre
support and now you have a WebGPU-ready GIS, table, graph and SQL support for 100M datasets!
Have a look: https://github.com/do-me/geospatial-atlas

Satellite map of România viewed from space. The country displays its distinctive shape, with the Carpathian Mountains forming a prominent arc across the center, appearing as dark-green, forested ridges. The mountain chain curves like a reversed 'C' or horseshoe, dividing România into three central regions. Inside this arc lies Transylvania, visible as a green elevated plateau. The southern region shows the Wallachian Plain in lighter browns and tans, indicating agricultural lands. The Danube River is visible along the southern border, and the Black Sea coastline appears on the east edge. The mountains show the highest elevations with some snow-capped peaks visible as white spots. The Danube Delta region appears as a distinctive green wetland area where the river meets the Black Sea.

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.
