Biodiversity Data from the GBIF Node Network.
galah
Overview
galah
is an R interface to biodiversity data hosted by the Global Biodiversity Information Facility (GBIF) and those members of the GBIF node network that maintain their own APIs (i.e. the ‘living atlases’). These organisations collate and store observations of individual life forms, using the ‘Darwin Core’ data standard. galah
was built and is maintained by the Science & Decision Support Team at the Atlas of Living Australia (ALA).
galah
enables users to locate and download species occurrence records (observations, specimens, eDNA records, etc.), taxonomic information, or associated media such as images or sounds, and to restrict their queries to particular taxa or locations. Users can specify which columns are returned by a query, or restrict their results to occurrences that meet particular data-quality criteria. All functions return a tibble
as their standard format.
The package is named for the bird of the same name (Eolophus roseicapilla), a widely-distributed endemic Australian species. The logo was designed by Ian Brennan.

Cheat sheet
Citations
To generate a citation for the package version you are using, you can run
citation(package = "galah")
If you’re using occurrence data downloaded through galah
in a publication, please generate a DOI and cite it. To request a DOI for a download of occurrence record, set mint_doi = TRUE
in a call to atlas_occurrences()
. To generate a citation for the downloaded occurrence records, pass the tibble
generated to atlas_citation()
.
# Download occurrence records with a DOI
occ <- atlas_occurrences(..., mint_doi = TRUE)
# See DOI
attr(occ, "doi")
# Generate citation
atlas_citation(occ)
