Course Description
R statistical software is becoming increasingly popular for spatial analysis and visualization—and for good reason. It is reproducible, flexible, and supported by a vast ecosystem of R packages dedicated to spatial data. An essential part of working with spatial data is visualization, not only for communication but also for exploration and analysis. This in-depth course focuses on the R package tmap, one of the most widely used packages for spatial data visualization. The course covers all key steps, from reading spatial data to publishing high-resolution static maps or interactive maps that can be embedded in web articles and dashboards. Participants will work with essential spatial data packages in particular sf, terra, and stars. The course also addresses key methodological aspects of spatial data visualization, including map projections, selecting the most appropriate visualization method for a given task, and choosing colorblind friendly color schemes that account for accessibility and cultural considerations. Innovative spatial visualization techniques are also explored via several tmap extension packages, including cartograms, glyph-based visualizations, and 3d maps.
What You’ll Learn
- Know how to use the core packages sf, terra, and stars to read and process spatial data in R, including joining data sources and performing geospatial data manipulations.
- Understand the methodological advantages and limitations of different map types, enabling informed decisions based on data characteristics and target users.
- Create various types of thematic maps.
- Be able to use tmap for exploring, analysing, and presenting spatial data.
- Recognize key considerations when selecting a suitable colour palette.
- Know how to export maps in various static and interactive formats.
- Be able to fine-tune map layouts in tmap, including adding map components, customizing legends, and incorporating map insets.
- Learn how to use tmap extension packages.
Course Format
Interactive Learning Format
Each day features a well-balanced combination of lectures and hands-on practical exercises, with dedicated time for discussing participants’ own data, time permitting.
Global Accessibility
All live sessions are recorded and made available on the same day, ensuring accessibility for participants across different time zones.
Collaborative Discussions
Open discussion sessions provide an opportunity for participants to explore specific research questions and engage with instructors and peers.
Comprehensive Course Materials
All code, datasets, and presentation slides used during the course will be shared with participants by the instructor.
Personalized Data Engagement
Participants are encouraged to bring their own data for discussion and practical application during the course.
Post-Course Support
Participants will receive continued support via email for 30 days following the course, along with on-demand access to session recordings for the same period.
Who Should Attend / Intended Audiences
This course is intended for academics and postgraduate students working on spatial data projects, as well as applied researchers and analysts in the public, private, or third sectors who require the reproducibility, speed, and flexibility of a command-line language like R for spatial data analysis and visualisation. It is also well-suited for data journalists aiming to produce engaging and informative maps for news stories, dashboards, and infographics, and for current R users seeking to update their skills with spatial data packages, particularly tmap. Participants should have a basic understanding of mathematical and statistical concepts and be comfortable using R, including tasks such as importing and exporting data, manipulating data frames, and creating simple exploratory plots. Familiarity with tidyverse packages—especially dplyr and tidyr—is recommended, as is experience with git.
Equipment and Software requirements
A laptop or desktop computer with a functioning installation of R and RStudio is required. Both R and RStudio are free, open-source programs compatible with Windows, macOS, and Linux systems.
A working webcam is recommended to support interactive elements of the course. We encourage participants to keep their cameras on during live Zoom sessions to foster a more engaging and collaborative environment.
While not essential, using a large monitor—or ideally a dual-monitor setup—can significantly enhance your learning experience by allowing you to view course materials and work in R simultaneously.
All necessary R packages will be introduced and installed during the workshop. A comprehensive list of required packages will also be shared with participants ahead of the course to allow for optional pre-installation.
