(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. Issues passed to this parameter filter results by the issue. One of many options. See here for definitions.

(character) The gadm id of the area occurrences are desired from.


A number or range between 0-1,000,000 which specifies the desired coordinate uncertainty. A coordinateUncertainty InMeters=1000 will be interpreted all records with exactly 1000m. Supports range queries, 'smaller,larger' (e.g., '1000,10000', whereas '10000,1000' wouldn't work).

(character) the life stage of the occurrence. One of many options.


(logical) identify potentially related records on GBIF.


A number or range. A value of "2000,*" means at least 2km from known centroids. A value of "0" would mean occurrences exactly on known centroids. A value of "0,2000" would mean within 2km of centroids. Max value is 5000.


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, datasetKey, 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


(character) a character vector of length 1 or greater. Required.


(numeric) minimum number of records to be included in the faceting results


(logical) Set to TRUE to still return counts for values that are not currently filtered. See examples. Default: FALSE

Faceting: All fields can be faceted on except for last "lastInterpreted", "eventDate", and "geometry"

You can do facet searches alongside searching occurrence data, and return both, or only return facets, or only occurrence data, etc.


(logical) whether to skip wellknown::validate_wkt call or not. passed down to check_wkt(). Default: TRUE


list of named curl options passed on to HttpClient. see curl::curl_options for curl options


additional facet parameters


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

Multiple values passed to a parameter

There are some parameters you can pass multiple values to in a vector, each value of which produces a different request (multiple different requests = c("a","b")). Some parameters allow multiple values to be passed in the same request (multiple same request = "a;b") in a semicolon separated string (e.g., 'a;b'); if given we'll do a single request with that parameter repeated for each value given (e.g., foo=a&foo=b if the parameter is foo).

See article Multiple Values.


Hierarchies are returned with each occurrence object. There is no option 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 hierarchies and metadata, or just metadata. If all hierarchies are the same we just return one for you.

curl debugging

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.


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)'

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 is deprecated since rgbif v3.8.0. Might return error, since the GBIF's polygon interpretation has changed.

    This method uses sf::st_make_grid and sf::st_intersection, which has two parameters cellsize and n. 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.


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
