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 onsf
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 thesf
,sp
,rgeos
, andrgdal
packages)
