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 <https://mapzen.com/documentation/elevation/elevation-service/>,
Mapzen Terrain Service <https://mapzen.com/documentation/terrain-tiles/>,
Amazon Web Services Terrain Tiles <https://aws.amazon.com/public-datasets/terrain/> and the USGS
Elevation Point Query Service <http://ned.usgs.gov/epqs/>.
