Data from GBIF

This function downloads species occurence records from the Global Biodiversity Information Facility (GBIF) data portal. You can download either a single species (if you append a '*' to the species name) or a subspecies of comparable level. You can download the data for an entire genus by using species='*'. Before using this function, please first check the GBIF data use agreement.

Keywords: spatial

Usage

gbif(genus, species="", ext=NULL, args=NULL, geo=TRUE, sp=FALSE, 
   removeZeros=FALSE, download=TRUE, ntries=5, nrecs=300, start=1, end=Inf)

Arguments

genus: character. genus name
species: character. species name. Use '*' to download the entire genus. Append '*' to the species name to get all naming variants (e.g. with and witout species author name) and sub-taxa
ext: Extent object to limit the geographic extent of the records. An extent can be created using functions like drawExtent and extent
args: character. Additional arguments to refine the query. See query parameters in https://www.gbif.org/developer/occurrence for more details
geo: logical. If TRUE, only records that have a georeference (longitude and latitude values) will be downloaded
sp: logical. If TRUE, geo will be set to TRUE and a SpatialPointsDataFrame will be returned
removeZeros: logical. If TRUE, all records that have a latitude OR longitude of zero will be removed if geo==TRUE, or set to NA if geo==FALSE. If FALSE, only records that have a latitude AND longitude that are zero will be removed or set to NA
download: logical. If TRUE, records will be downloaded, else only the number of records will be shown
ntries: integer. How many times should the function attempt to download the data, if an invalid response is returned (perhaps because the GBIF server is very busy)
nrecs: integer. How many records to download in a single request (max is 300)?
start: integer. Record number from which to start requesting data
end: integer. Last record to request
