The 1 km (30 arc seconds) data were aggregated from SRTM 90 m resolution data and supplemented with the GTOP30 data for high latitudes (>60 degrees).

Usage

elevation_3s(lon, lat, path, ...)
elevation_30s(country, path, mask=TRUE, subs="", ...)
elevation_global(res, path, ...)

Arguments

lon	numeric. Longitude
lat	numeric. Latitude
path	character. Path for storing the downloaded data. See geodata_path
country	character. Country name or code
mask	logical. set grid cells outside of the country boundaries to NA
subs	character
res	numeric. Valid resolutions are 10, 5, 2.5, and 0.5 (minutes of a degree)
...	additional arguments passed to download.file
