## Workshop approach
    
### Rstudio

We will be working in an Rstudio project. I recommend this workflow for all your projects because it keeps your work portable and self contained

We will also be using Rmd notebooks. I like them because you can see the outputs of code as you write. You can also make notes around your code using markdown. _See further resources for more details._ 

### Live coding

The majority of the workshop I will be live coding `r emo::ji("fearful")` so that you can follow along. You will get a lot more out of the workshop if you do.

## Workshop aims and objectives

- Understand the basics of GIS
- Understand spatial data types and formats
- Be able to work with, manipulate, combine and extract spatial data in R
- Be able to plot spatial


## Why GIS in R

1. It's free
2. It's powerful especially in terms of spatial analysis and statistics
3. It's a scripted language so encourages reusable, reproducible workflows
4. Recent additions to the R geospatial ecosystem (in particular package `sf`) have drastically simplified spatial data classes and workflows.
