This tag refers to the R Terra package. For questions about NASA's Terra satellite, use the tags of its censors like Aster, Ceres, or Modis.
Terra is a spatial data handling package for the R programming language, released in March 2020. The package was created by Robert J. Hijmans and his colleagues Bivand, Forner Ooms and Pebesma, and can manipulate both rasters and vectors (points, lines, and polygons).
Terra was built to enable higher computational speed while maintaining simplicity in its commands, and is, therefore, meant replace to the popular raster package, the former standard dependency for raster analysis in R.
In Terra, SpatRaster is the class used for reading, manipulating, and conversion of raster data, like satellite imagery, while SpatVector is the class used for reading and analyzing vector data. To combine multiple vectors or rasters in one variable, collections can be used which are intuitively called SpatRasterCollection and SpatVectorCollection.
Terra can be mastered by studying the documentation or the help guide.
Any question about the Terra package in R should have this tag. For questions about NASA's Terra satellite, use the tags of its instruments like Aster or
Modis
