get_aws_points

Either a <code>data.frame</code> with x (e.g. longitude) as the 
first column and y (e.g. latitude) as the second column, a 
<code>SpatialPoints</code>/<code>SpatialPointsDataFrame</code>, or a 
<code>sf</code> <code>POINT</code> or <code>MULTIPOINT</code> object. 
Elevation for these points will be returned in the 
originally supplied class.

locations

The zoom level to return. The zoom ranges from 1 to 14. Resolution
of the resultant raster is determined by the zoom and latitude. For 
details on zoom and resolution see the documentation from Mapzen at 
<a href="https://mapzen.com/documentation/terrain-tiles/data-sources/#what-is-the-ground-resolution">https://mapzen.com/documentation/terrain-tiles/data-sources/#what-is-the-ground-resolution</a>. 
default value is 5 is supplied.

Character string of either meters or feet. Conversions for 
'aws' are handled in R as the AWS terrain tiles are served in 
meters.

Arguments to be passed to <code>get_elev_raster</code>

Function for accessing elevation data from AWS and extracting the elevations

internal

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