pt_df


Example data frame of locations for use in examples and text


datasets

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/>.
