Intro to Geospatial Data with R

The Coordinate Reference System or CRS tells R where the raster is located in geographic space and what method should be used to “flatten” or project the raster.

A single raster file can contain multiple bands or layers.

Spatial objects in sf are similar to standard data frames except for a geometry list-column.

It is important to know the projection (if any) of your point data prior to converting to a spatial object.
