An R package for accessing elevation data from various sources
elevatr package currently provides access to elevation data from AWS Open Data Terrain Tiles for raster digital elevation models. For point elevation data,the USGS Elevation Point Query Service) may be used. Additional elevation data sources may be added.
Current plan for this package includes just two functions to access elevation web services:
get_elev_point(): Get point elevations using the USGS Elevation Point Query Service (for the US Only) . This will accept a data frame of x (long) and y (lat) or a SpatialPoints/SpatialPointsDataFame as input. A SpatialPointsDataFrame is returned.
get_elev_raster(): Get elevation data as a raster (e.g. a Digital Elevation Model) from the AWS Open Data Terrain Tiles. Other sources may be added later. This will accept a data frame of of x (long) and y (lat) or any
rasterobject as input and will return a
rasterobject of the elevation tiles that cover the bounding box of the input spatial data.
Version 0.2.0 of this package is currently available from CRAN and may be installed by:
The development version (this repo) may installed with
