Vector data models for geographic information

Today we’ll focus on learning the vector data model and how it is implemented within the spatial packages in the R computing environment.

Resources

• The introductory vignette for the sf package has a lot of useful info on sf objects and conventions.

• Section 2.2 on Vector Data and Sections 5.1-5.3 on Geographic Operations in Lovelace et al. (Lovelace et al. 2019) - for more details about vectors and geometric operations on vectors.

• Section 3.1 and 3.2 of Spatial Data Science, a bookdown project by Edzer Pebesma and Roger Bivand (of the sf, sp, rgeos, and rgdal packages)
