abstract: Support for simple feature access, a standardized way to encode and analyze
  spatial vector data. Binds to 'GDAL' <https://doi.org/10.5281/zenodo.5884351> for
  reading and writing data, to 'GEOS' <https://doi.org/10.5281/zenodo.11396894> for
  geometrical operations, and to 'PROJ' <https://doi.org/10.5281/zenodo.5884394> for
  projection conversions and datum transformations. Uses by default the 's2' package
  for geometry operations on geodetic (long/lat degree) coordinates.
