gecevar stands for “GEtting Climatic and other Environmental
VARiables”. The package contains functions for downloading climate and
environmental data from open and free online datasets for any region of
the world. The data can be used for ecological studies. The area of
interest can be a country, state or project area and is defined by an
extent, vector file or country iso-code. Data comes from a variety of
sources (e.g. Chelsa, OpenStreetMap, TropicalMoistForest, SRTMv4.1,
SoilGrids). Climate and environmental data are available as multiband
raster files at a resolution and in the coordinate reference system
specified by the user. When possible, the package uses the properties of
Cloud Optimized GeoTIFF (COGs) files to
download only the portion of the global datasets corresponding to the
area of interest, reducing download time. The package uses
GDAL and the R libraries
terra and
sf for optimized processing of
raster and vector geospatial data.
Make sure GDAL and GRASS GIS are installed on your system.
