An R package for accessing elevation data from various sources

The elevatr package currently provides access to elevation data from from Mapzen (Mapzen Tile Service for raster digital elevation models. For point elevation data, either the Mapzen Elevation Service or 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 Mapzen Elevation Service or 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 Mapzen Terrain GeoTIFF Service. Other sources may be added later. This will accept a data frame of of x (long) and y (lat) or any sp or raster object as input and will return a raster object of the elevation tiles that cover the bounding box of the input spatial data.


Version 0.1.1 of this package is currently available from CRAN and may be installed by:


The development version (this repo) may installed with devtools:


API Keys

The elevatr packages will look for API keys stored as environment variables. Currently the only API key required is from Mapzen. Go to and create a new key. Copy this key and add to your .Renviron file. This can be done using the method suggested here. For example:

    file=file.path(normalizePath("~/"), ".Renviron"),

You will need to restart R, but once the key is there you are good to go on that machine. elevatr will access the key via Sys.getenv("mapzen_key")
