A copy of the 'minimal_mesh' data set from the silicate package, with coordinate reference system information added.
sfx
is the old-style PROJ.4 and EPSG code CRS (prior to sf 0.8-1).
sfx_new
is the new-style WKT2, with user input.
do not use this data in real situations, or as exemplary of the 'sf' format. It was created purely to add examples to this package.
