# Preface {.unnumbered}

This manual is tended both for R users wishing to set up spatial data peocessing and for users wishing to use R to carry out the tasks that they usually carry out with GIS. The main steps in the processing of geographic information are covered. Emphasis is placed on the processing of vector data but a part is still dedicated to raster data.

**How to use the manual**\
The RStudio project containing all the data used in the manual is available [here](https://github.com/rCarto/geodata/archive/refs/heads/main.zip). Once the file is unzipped it is possible to test all the manipulations proposed in the RStudion project.

**Context**\
This manual has been designed from the courses "[Géomatique avec R](https://rcarto.github.io/geomatique_avec_r/)" and "[Cartographie avec R](https://rcarto.github.io/cartographie_avec_r/)" by Timothée Giraud and Hugues Pecout. It has been translated and its examples have been adapted to the geographical distribution of the audience.
