Understanding the Basics
At its core, spatial data analysis in R involves manipulating and analyzing geospatial data to extract meaningful information. This data comes in two primary forms: raster and vector. Raster data is essentially a grid of cells or pixels, each with a specific value representing a geographic attribute, such as elevation or temperature. Vector data, on the other hand, represents geographic entities through points, lines, and polygons, which could denote locations, paths, or areas, respectively....
