(numeric) A taxon key from the GBIF backbone. All included and synonym taxa are included in the search, so a search for aves with taxononKey=212 (i.e. /occurrence/search?taxonKey=212) will match all birds, no matter which species. You can pass many keys by passing occ_search in a call to an lapply-family function (see last example below).


A scientific name from the GBIF backbone. All included and synonym taxa are included in the search.


The 2-letter country code (as per ISO-3166-1) of the country in which the occurrence was recorded. See here https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2

An identifier of any form assigned by the source within a physical collection or digital dataset for the record which may not unique, but should be fairly unique in combination with the institution and collection code.


The 4 digit year. A year of 98 will be interpreted as AD 98. Supports range queries, smaller,larger (e.g., '1990,1991', whereas '1991,1990' wouldn't work)


The month of the year, starting with 1 for January. Supports range queries, smaller,larger (e.g., '1,2', whereas '2,1' wouldn't work)

Depth in meters relative to elevation. For example 10 meters below a lake surface with given elevation. Supports range queries, smaller,larger (e.g., '5,30', whereas '30,5' wouldn't work)


An identifier of any form assigned by the source to identify the institution the record belongs to. Not guaranteed to be que.


An identifier of any form assigned by the source to identify the physical collection or digital dataset uniquely within the text of an institution.


(logical) Includes/excludes occurrence records which contain spatial issues (as determined in our record interpretation), i.e. hasGeospatialIssue=TRUE returns only those records with spatial issues while hasGeospatialIssue=FALSE includes only records without spatial issues. The absence of this parameter returns any record with or without spatial issues.


(character) One or more of many possible issues with each occurrence record. See Details. Issues passed to this parameter filter results by the issue.

(character) The name of the water body in which the locations occur


(character) The specific description of the place.


Number of records to return. Default: 500. Note that the per request maximum is 300, but since we set it at 500 for the function, we do two requests to get you the 500 records (if there are that many). Note that there is a hard maximum of 100,000, which is calculated as the limit+start, so start=99,000 and limit=2000 won't work


Record number to start at. Use in combination with limit to page through results. Note that we do the paging internally for you, but you can manually set the start parameter


(character) Default ('all') returns all fields. 'minimal' returns just taxon name, key, latitude, and longitute. Or specify each field you want returned by name, e.g. fields = c('name','latitude','elevation').


Defunct. All components (meta, hierarchy, data, media, facets) are returned now; index to the one(s) you want. See occ_data() if you just want the data component

protocol parameter options:

  • BIOCASE - A BioCASe protocl compliant service.

  • DIGIR - A DiGIR service endpoint.

  • DIGIR_MANIS - A DiGIR service slightly modified for the MANIS network.

  • DWC_ARCHIVE - A Darwin Core Archive as defined by the Darwin Core Text Guidelines.

  • EML - A single EML metadata document in any EML version.

  • FEED - Syndication feeds like RSS or ATOM of various flavors.

  • OAI_PMH - The Open Archives Initiative Protocol for Metadata Harvesting.

  • OTHER - Any other service not covered by this enum so far.

  • TAPIR - A TAPIR service.

  • TCS_RDF - Taxon Concept data given as RDF based on the TDWG ontology.

  • TCS_XML - A Taxon Concept Schema document.

  • WFS - An OGC Web Feature Service.

  • WMS - An OGC Web Map Service.

Multiple parmeters: Note that you can pass in a vector to one of taxonKey, scientificName, datasetKey, catalogNumber, recordedBy, geometry, country, publishingCountry, recordNumber, search, institutionCode, collectionCode, decimalLatitude, decimalLongitude, depth, year, typeStatus, lastInterpreted, continent, or mediatype parameters in a function call, but not a vector >1 of these parameters at the same time

Hierarchies: hierarchies are returned wih each occurrence object. There is no option no to return them from the API. However, within the occ_search function you can select whether to return just hierarchies, just data, all of data and hiearchies and metadata, or just metadata. If all hierarchies are the same we just return one for you.

Data: By default only three data fields are returned: name (the species name), decimallatitude, and decimallongitude. Set parameter minimal=FALSE if you want more data.

Nerds: You can pass parameters not defined in this function into the call to the GBIF API to control things about the call itself using curlopts. See an example below that passes in the verbose function to get details on the http call.

Scientific names vs. taxon keys: In the previous GBIF API and the version of rgbif that wrapped that API, you could search the equivalent of this function with a species name, which was convenient. However, names are messy right. So it sorta makes sense to sort out the species key numbers you want exactly, and then get your occurrence data with this function. GBIF has added a parameter scientificName to allow searches by scientific names in this function - which includes synonym taxa. Note: that if you do use the scientificName parameter, we will check internally that it's not a synonym of an accepted name, and if it is, we'll search on the accepted name. If you want to force searching by a synonym do so by finding the GBIF identifier first with any name_* functions, then pass that ID to the taxonKey parameter.

WKT: Examples of valid WKT objects:

  • 'POLYGON((-19.5 34.1, 27.8 34.1, 35.9 68.1, -25.3 68.1, -19.5 34.1))'

  • 'MULTIPOLYGON(((-123 38,-116 38,-116 43,-123 43,-123 38)),((-97 41,-93 41,-93 45,-97 45,-97 41)))'

  • 'POINT(-120 40)'

  • 'LINESTRING(3 4,10 50,20 25)'

  • 'LINEARRING' ???' - Not sure how to specify this. Anyone?

Note that GBIF expects counter-clockwise winding order for WKT. You can supply clockwise WKT, but GBIF treats it as an exclusion, so you get all data not inside the WKT area. occ_download() behaves differently in that you should simply get no data back at all with clockwise WKT.

Long WKT: Options for handling long WKT strings: Note that long WKT strings are specially handled when using occ_search or occ_data. Here are the three options for long WKT strings (> 1500 characters), set one of these three via the parameter geom_big:

  • asis - the default setting. This means we don't do anything internally. That is, we just pass on your WKT string just as we've done before in this package.

  • axe - this option uses the geoaxe package to chop up your WKT string in to many polygons, which then leads to a separate data request for each polygon piece, then we combine all dat back together to give to you. Note that if your WKT string is not of type polygon, we drop back to asisas there's no way to chop up linestrings, etc. This option will in most cases be slower than the other two options. However, this polygon splitting approach won't have the problem of the disconnect between how many records you want and what you actually get back as with the bbox option.

    This method uses chop, which uses GridTopologyfrom the sp package, which has two parameters cellsize and cells.dim that we use to chop up polygons. You can tweak those parameters here by tweaking geom_size and geom_n. geom_size seems to be more useful in toggling the number of WKT strings you get back.

    See wkt_parse to manually break make WKT bounding box from a larger WKT string, or break a larger WKT string into many smaller ones.

  • bbox - this option checks whether your WKT string is longer than 1500 characters, and if it is we create a bounding box from the WKT, do the GBIF search with that bounding box, then prune the resulting data to only those occurrences in your original WKT string. There is a big caveat however. Because we create a bounding box from the WKT, and the limit parameter determines some subset of records to get, then when we prune the resulting data to the WKT, the number of records you get could be less than what you set with your limit parameter. However, you could set the limit to be high enough so that you get all records back found in that bounding box, then you'll get all the records available within the WKT.

Range queries: A range query is as it sounds - you query on a range of values defined by a lower and upper limit. Do a range query by specifying the lower and upper limit in a vector like depth='50,100'. It would be more R like to specify the range in a vector like c(50,100), but that sort of syntax allows you to do many searches, one for each element in the vector - thus range queries have to differ. The following parameters support range queries.

  • decimalLatitude

  • decimalLongitude

  • depth

  • elevation

  • eventDate

  • lastInterpreted

  • month

  • year

Issue: The options for the issue parameter (from https://gbif.github.io/gbif-api/apidocs/org/gbif/api/vocabulary/OccurrenceIssue.html):

  • BASIS_OF_RECORD_INVALID The given basis of record is impossible to interpret or seriously different from the recommended vocabulary.

  • CONTINENT_COUNTRY_MISMATCH The interpreted continent and country do not match up.

  • COORDINATE_ROUNDED Original coordinate modified by rounding to 5 decimals.

  • COUNTRY_COORDINATE_MISMATCH The interpreted occurrence coordinates fall outside of the indicated country.

  • COUNTRY_DERIVED_FROM_COORDINATES The interpreted country is based on the coordinates, not the verbatim string information.

  • ELEVATION_MIN_MAX_SWAPPED Set if supplied min > max elevation

  • ELEVATION_NON_NUMERIC Set if elevation is a non numeric value

  • ELEVATION_NOT_METRIC Set if supplied elevation is not given in the metric system, for example using feet instead of meters

  • ELEVATION_UNLIKELY Set if elevation is above the troposphere (17km) or below 11km (Mariana Trench).

  • GEODETIC_DATUM_ASSUMED_WGS84 Indicating that the interpreted coordinates assume they are based on WGS84 datum as the datum was either not indicated or interpretable.

  • GEODETIC_DATUM_INVALID The geodetic datum given could not be interpreted.

  • IDENTIFIED_DATE_INVALID The date given for dwc:dateIdentified is invalid and cant be interpreted at all.

  • IDENTIFIED_DATE_UNLIKELY The date given for dwc:dateIdentified is in the future or before Linnean times (1700).

  • MODIFIED_DATE_INVALID A (partial) invalid date is given for dc:modified, such as a non existing date, invalid zero month, etc.

  • MULTIMEDIA_DATE_INVALID An invalid date is given for dc:created of a multimedia object.

  • MULTIMEDIA_URI_INVALID An invalid uri is given for a multimedia object.

  • PRESUMED_NEGATED_LATITUDE Latitude appears to be negated, e.g. 32.3 instead of -32.3

  • REFERENCES_URI_INVALID An invalid uri is given for dc:references.

  • TAXON_MATCH_FUZZY Matching to the taxonomic backbone can only be done using a fuzzy, non exact match.

  • TAXON_MATCH_HIGHERRANK Matching to the taxonomic backbone can only be done on a higher rank and not the scientific name.

  • TAXON_MATCH_NONE Matching to the taxonomic backbone cannot be done cause there was no match at all or several matches with too little information to keep them apart (homonyms).

  • TYPE_STATUS_INVALID The given type status is impossible to interpret or seriously different from the recommended vocabulary.

  • ZERO_COORDINATE Coordinate is the exact 0/0 coordinate, often indicating a bad null coordinate.

Counts: There is a slight difference in the way records are counted here vs. results from occ_count. For equivalent outcomes, in this function use hasCoordinate=TRUE, and hasGeospatialIssue=FALSE to have the same outcome using occ_count with isGeoreferenced=TRUE


An object of class gbif, which is a S3 class list, with slots for metadata (meta), the occurrence data itself (data), the taxonomic hierarchy data (hier), and media metadata (media). In addition, the object has attributes listing the user supplied arguments and whether it was a 'single' or 'many' search; that is, if you supply two values of the datasetKey parameter to searches are done, and it's a 'many'. meta is a list of length four with offset, limit, endOfRecords and count fields. data is a tibble (aka data.frame). hier is a list of data.frames of the unique set of taxa found, where each data.frame is its taxonomic classification. media is a list of media objects, where each element holds a set of metadata about the media object.


Maximum number of records you can get with this function is 100,000. See https://www.gbif.org/developer/occurrence
