This package offers a set of handy tool functions for reading and processing spatial data, to prep it for use with tmap. The aim of these functions is to supply the workflow to create thematic maps, e.g. read shape files, set map projections, append data, calculate areas and distances, and query OpenStreetMap. The visualization of thematic maps can be done with the tmap package. Use the append_data() function to join more attribute data based on key column values.
