Coordinates and Geometries

HES 505 Fall 2024: Session 6

Carolyn Koehn

Objectives

  • Understand the linkage between location, coordinates, coordinate reference systems, and geometry

  • Access and manipulate geometries in R with sf (and terra)

  • Define geometry in the context of vector objects and troubleshoot common problems

  • Change the CRS for vectors and rasters (and understand the implications)

But first…

Getting more acquainted with R

  • Objects, classes, functions, oh my…

  • Intuition for the tidyverse

  • Getting used to pipes (%>% or |>)

  • Learning to prototype
