 Description: Several web services are available that provide access to elevation
              data. This package provides access to many of those services and 
-             returns elevation data either as a simple features POINT/MULTIPOINT 
-             from point elevation services or as a raster RasterLayer from raster 
-             elevation services. In future versions, elevatr will drop 
-             support for raster RasterLayers and will instead return terra 
-             SpatRaster objects. Currently, the package supports access to the
-             Amazon Web Services Terrain Tiles <https://registry.opendata.aws/terrain-tiles/>, 
-             the Open Topography Global Datasets API <https://opentopography.org/developers/>, 
-             and the USGS Elevation Point Query Service <https://apps.nationalmap.gov/epqs/>.
