COURSE FORMAT

This is a ‘LIVE COURSE’ – the instructor will be delivering lectures and coaching attendees through the accompanying computer practical’s via video link, a good internet connection is essential.

TIME ZONE

TIME ZONE – `Central European Standard Time – however all sessions will be recorded and made available allowing attendees from different time zones to follow.

Please email oliverhooker@prstatistics.com for full details or to discuss how we can accommodate you.

About This Course

R statistical software is becoming increasingly popular for spatial analysis and mapping. This is partially due to a large number of R packages devoted to applying various spatial methods. These packages, however, are being revised, updated, or even superseded to allow for better performance, simpler user interface, or expanded capabilities. Substantial recent changes in R spatial packages include developing the ‘sf’ package as a successor of ‘sp’, creation of `terra` as a successor of `raster`, and establishing the `stars` package. Additionally, all of these packages were affected by the recent major updates of the PROJ library. In this course, we will learn to use key packages for the analysis of spatial data, both vector (‘sf’) and raster (‘terra’), and see how they differ from their older counterparts, ‘sp’ and ‘raster’. Another important aspect of the course will be to understood spatial projections and coordinate systems, how the recent PROJ changes affect R users, and how to adjust to them.

By the end of the course, participants should:

  • Understand the basic concepts behind spatial analysis ecosystem in R
  • Know how packages such as sp/rgeos/rgdal/raster differ from their successors sf/terra/star
  • Be able to switch from using packages such as sp/rgeos/rgdal/raster to sf/terra/stars
  • Understood the basic concepts behind spatial projections, and how PROJ.7 differs from PROJ4
  • Know how to deal with coordinate reference systems in R
  • Have the confidence to switch from PROJ4 to PROJ7 (i.e., for instance, adjusting old scripts based on PROJ4)?
Intended Audiences
  • Academics and post-graduate students working on projects related to spatial data
  • Applied researchers and analysts in public, private or third-sector organizations who need the reproducibility, speed and flexibility of a command-line language such as R for spatial data analysis
  • Current R users wanting to update your knowledge, including switch from using `sp` to `sf`, and from `raster` to `terra`
  • The course is designed for intermediate R users interested in understanding modern tools for spatial data analysis in R and R beginners who have prior experience with geographic data and other spatial software.

Course Details

Time zone – Central Europe Standard Time

Availability – TBC

Duration – 2 days

Contact hours – Approx. 15 hours

ECT’s – Equal to 1 ECT’s

Language – English

Teaching Format

The course will be a mixture of theoretical and practical. Each concept will be first described and explained, and next the attendees will exercise the topics using provided data sets.

Assumed quantitative knowledge

Understanding basic GIS concepts, such as spatial vector, spatial raster, coordinate reference systems would be beneficial, but is not necessary.

Assumed computer background

Attendees should already have experience with R and be able to read csv files, create simple plots, and manipulate data frames. The experience of using some basic R spatial packages, such as sp or raster would be beneficial.

However, if you do not have R experience but already use GIS software and have a strong understanding of geographic data types, and some programming experience, the course may also be appropriate for you.

Equipment and software requirements

A laptop computer with a working version of R or RStudio is required. R and RStudio are both available as free and open source software for PCs, Macs, and Linux computers.

Participants should be able to install additional software on their own computer during the course (please make sure you have administration rights to your computer). 

A large monitor and a second screen, although not absolutely necessary, could improve the learning experience. Participants are also encouraged to keep their webcam active to increase the interaction with the instructor and other students.

COURSE PROGRAMME

Wednesday 22nd

Classes from 09:00 to 17:00
Overview of spatial analysis ecosystem in R
• available R packages for spatial analysis in R
• how do R packages represent spatial objects, and how are they connected with each other
• importance of using the more recent R spatial packages, such as ‘sf’ or ‘terra’
• main concepts behind map projections (geoids, datums, geographic/projected coordinates, types of projections, etc.)
• implementation of these concepts in the PROJ library (used by most R spatial packages)
• differences between PROJ.4 and its newer versions (e.g. PROJ.7)
Spatial vector data analysis in R
• spatial vector data processing & analysis in R
• read/write/and visualize spatial vector data
• differences between ‘sp’/’rgdal’/’rgeos’ and ‘sf’
• moving from ‘sp’ to ‘sf’ for spatial vector data processing & analysis
• spherical geometry: how this concept was recently implemented in sf, and what is an impact of this implementation

Thursday 23rd

Classes from 09:00 to 17:00
Spatial raster data analysis in R
