Week 4

Transforming spatial data attributes

Overview

This week is to learn to use {dplyr} and {sf} in combination to create and manipulate attributes associated with spatial data.

Key Objectives

• Review key concepts of simple features in R
• Introduce key concepts for spatial attribute data (e.g. point vs. block support)
• Practice using {sf} functions for geometric confirmation (st_intersects(), st_disjoint()) and geometric measurement (st_area(), st_length(), st_distance())
• Discuss ideas for final projects

Prepare
