  "Description": "Several web services are available that provide access to\nelevation data. This package provides access to many of those\nservices and returns elevation data either as an 'sf' simple\nfeatures object from point elevation services or as a 'raster'\nobject from raster elevation services. In future versions,\n'elevatr' will drop support for 'raster' and will instead\nreturn 'terra' objects. Currently, the package supports access\nto the Amazon Web Services Terrain Tiles\n<https://registry.opendata.aws/terrain-tiles/>, the Open\nTopography Global Datasets API\n<https://opentopography.org/developers/>, and the USGS\nElevation Point Query Service\n<https://apps.nationalmap.gov/epqs/>.",
