Several web services are available that provide access to elevation data. This package provides access to several of those services and returns elevation data either as a SpatialPointsDataFrame from point elevation services or as a raster object from raster elevation services. Currently, the package supports access to the Mapzen Elevation Service , Mapzen Terrain Service , Amazon Web Services Terrain Tiles and the USGS Elevation Point Query Service .
