Some of you are already familiar with geobr, an R package that we developed in Ipea to facilitate downloading official spatial data sets of Brazil (a quick intro to geobr here). The stable version 1.0 was published on CRAN a couple of months ago. Since then, we have added some new data sets.
geobr now brings official spatial data of natural biomes, indigenous lands of all ethnicities in Brazil according to stage of demarcation, and risk areas prone to landslides and floods in Brazil. These data sets are currently only available in the development version of the package, wich can be installed with devtools::install_github("ipeaGIT/geobr") .
