What a delight to read this book/project 😃 😃 https://tmap.geocompx.org/ #rstats #gis #gisChat Many thanks to @nowosad and Martijn Tennekes for putting it together. Tmap is my very favorite R library for creating maps ❤️

Spatial Data Visualization with tmap

“Spatial Data Visualization with tmap: A Practical Guide to Thematic Mapping in R” is a free, open-source book that teaches you how to create static and interactive maps using the tmap package in R. Covering core concepts in thematic cartography, map design, and spatial visualization, this guide provides step-by-step approaches to help you produce high-quality maps for reports, presentations, and web applications.

Thanks to great feedback and input from the #rstats #rspatial community, the ISC grant proposal about modernizing R's web-mapping capabilities is coming along nicely... If you have anything to add, you can do so until tomorrow, when I will submit to @RConsortium

Introducing SedonaDB: A single-node analytical database engine with geospatial as a first-class citizen - Apache Sedona

Apache Sedona is a cluster computing system for processing large-scale spatial data. Sedona extends existing cluster computing systems, such as Apache Spark, Apache Flink, and Snowflake, with a set of out-of-the-box distributed Spatial Datasets and Spatial SQL that efficiently load, process, and analyze large-scale spatial data across machines.
