Building Databases with Location

Content for Wednesday, October 9, 2024

Today we’ll continue our development of attributes (or covariates) in our spatial databases. We’ll look at developing attributes that describe various geographic properties along with joining and subsetting based on locations.

Resources

  • The Spatial Data Operations Chapter in (Lovelace et al. 2019) makes the concepts of a network concrete (literally) by using a transportation route example to illustrate the various components of a network analysis in R.

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

Objectives

By the end of today, you should be able to:

  • Generate new features using geographic data

  • Use topological subsetting to reduce features based on geography

  • Use spatial joins to add attributes based on location
