Course Description

There has never been a better time to use R for spatial analysis! The brand new sf package has made working with vector data in R a breeze and the raster package provides a set of powerful and intuitive tools to work gridded data like satellite imagery. Instead of the painful process of performing your spatial analysis in GIS systems like ArcGIS or QGIS and then shuffling your results into another system for analysis you can move your entire spatial analysis workflow into R. In this course you will learn why the sf package is rapidly taking over spatial analysis in R. You will read in spatial data, manipulate vectors using the dplyr package and learn how to work with coordinate reference systems. You'll also learn how to perform geoprocessing of vectors including buffering, spatial joins, computing intersections, simplifying and measuring distance. With rasters you will aggregate, reclassify, crop, mask and extract. The last chapter of the course is devoted to showing you how to make maps in R with the ggplot2 and tmap packages and performing a fun mini-analysis that brings together all your new skills.

    Vector and Raster Spatial Data in R

    Free

    An introduction to import/export, learning the formats and getting to know spatial data. Some discussion of why we're using sf rather than sp.

    Conducting spatial analysis with the sf and raster packages

    Now that you have learned about sf and raster objects and have prepared your layers for analysis we can begin conducting true spatial analysis. Both sf and raster have a suite of functions that allow you to do single-layer kinds of analysis like buffering and computing hulls as well as multi-layer operations like intersections, overlaps, masking and clipping.

I've used other sites—Coursera, Udacity, things like that—but DataCamp's been the one that I've stuck with.
