## Overview

This repository is an instructional book, not a GIS application: readers use its ordered R Markdown chapters to learn spatial analysis with R, from GIS fundamentals and geographic data through mapping, spatial operations, and quantitative geography. The tree also includes datasets for practical examples. Chapter topics and available data collections are clear from the filenames, but the chapter source was not sampled, so specific example-to-dataset links are not asserted.

Main entry points: [`index.Rmd`](https://github.com/chiajung-yeh/spatial-analysis/blob/master/index.Rmd) (Book entry), [`01-Basic-Knowledge-on-GIS.Rmd`](https://github.com/chiajung-yeh/spatial-analysis/blob/master/01-Basic-Knowledge-on-GIS.Rmd) (GIS foundations), [`02-Data-Visualization-with-Maps.Rmd`](https://github.com/chiajung-yeh/spatial-analysis/blob/master/02-Data-Visualization-with-Maps.Rmd) (Map visualization), [`03-Geographic-Data.Rmd`](https://github.com/chiajung-yeh/spatial-analysis/blob/master/03-Geographic-Data.Rmd) (Geographic data)
