gfwr
: Access data from Global Fishing Watch APIs Important
This version ofgfwr
gives access to Global Fishing Watch API version 3. Starting April 30th, 2024, this is the official API version. To install the previous version that communicated with API version 2, please refer to branchAPIv2
in this repository.remotes::install_github("GlobalFishingWatch/gfwr", ref = "APIv2")
The gfwr
R package is a simple wrapper for the Global Fishing Watch
(GFW)
APIs.
It provides convenient functions to freely pull GFW data directly into R
in tidy formats.
The package currently works with the following APIs:
Note: See the Terms of Use page for GFW APIs for information on our API licenses and rate limits.
You can install the most recent version of gfwr
using:
# Check/install remotes
if (!require("remotes"))
install.packages("remotes")
remotes::install_github("GlobalFishingWatch/gfwr")
gfwr
is also in the rOpenSci
R-universe, and can
be installed like this:
install.packages("gfwr",
repos = c("https://globalfishingwatch.r-universe.dev",
"https://cran.r-project.org"))
Once everything is installed, you can load and use gfwr
in your
scripts with library(gfwr)
library(gfwr)
The use of gfwr
requires a GFW API token, which users can request from
the GFW API Portal.
Save this token to your .Renviron
file using
usethis::edit_r_environ()
and adding a variable named GFW_TOKEN
to
the file (GFW_TOKEN="PASTE_YOUR_TOKEN_HERE"
). Save the .Renviron
file and restart the R session to make the edit effective.
Then use the gfw_auth()
helper function to inform the key on your
function calls. You can use gfw_auth()
directly or save the
information to an object in your R workspace every time and pass it to
subsequent gfwr
functions.
So you can do:
key <- gfw_auth()
or this
key <- Sys.getenv("GFW_TOKEN")
Note:
gfwr
functions are set to usekey = gfw_auth()
by default.
The get_vessel_info()
function allows you to get vessel identity
details from the GFW Vessels
API.
There are two search types: search
, and id
.
search
is performed by using parameters query
for basic searches
and where
for advanced searchers using SQL expressions
query
takes a single identifier that can be the MMSI, IMO,
callsign, or shipname as input and identifies all vessels that
match.where
search allows for the use of complex search with logical
clauses (AND, OR) and fuzzy matching with terms such as LIKE, using
SQL syntax (see examples in the function)includes
adds information from public registries. Options are
“MATCH_CRITERIA”, “OWNERSHIP” and “AUTHORIZATIONS”To get information of a vessel using its MMSI, IMO number, callsign or
name, the search can be done directly using the number or the string.
For example, to look for a vessel with MMSI = 224224000
:
get_vessel_info(query = 224224000,
search_type = "search",
key = key)

To do more specific searches (imo = '8300949'
), combine different
fields (imo = '8300949' AND ssvid = '214182732'
) and do fuzzy matching
("shipname LIKE '%GABU REEFE%' OR imo = '8300949'"

id
search allows the user to specify a vector of vesselId
sNote:
vesselId
is an internal ID generated by GFW to connect data accross APIs and involves a combination of vessel and tracking data information. It can be retrieved usingget_vessel_info()
and fetching the vector of responses inside$selfReportedInfo$vesselId
. See the identity vignette for more information.
To search by vesselId
, use parameter ids
and specify
search_type = "id"
:
get_vessel_info(ids = "8c7304226-6c71-edbe-0b63-c246734b3c01",
search_type = "id",

This is useful especially because a vessel can have different
vesselId
s in time. Check the function documentation for examples with
the other function arguments and our dedicated
vignette
for more information about vessel identity .
The get_event()
function allows you to get data on specific vessel
activities from the GFW Events
API.
Event types include apparent fishing events, potential transshipment
events (two-vessel encounters and loitering by refrigerated carrier
vessels), port visits, and AIS-disabling events (“gaps”). Find more
information in our caveat
documentation.
The Events API uses vesselId
as input, so you always need to use
get_vessel_info()
first to extract vesselId
from $selfReportedInfo
in the response.
vessel_info <- get_vessel_info(query = 224224000, key = key)
id <- vessel_info$selfReportedInfo$vesselId[1]
To get a list of port visits for that vessel:
get_event(event_type = 'PORT_VISIT',
vessels = id,
confidences = 4,
key = key
)

When a date range is provided to get_event()
using both start_date
and end_date
, any event overlapping that range will be returned,
including events that start prior to start_date
or end after
end_date
. If just start_date
or end_date
are provided, results
will include all events that end after start_date
or begin prior to
end_date
, respectively.
Note:
Because encounter events are events between two vessels, a single event will be represented twice in the data, once for each vessel. To capture this information and link the related data rows, theid
field for encounter events includes an additional suffix (1 or 2) separated by a period. Thevessel
field will also contain different information specific to each vessel.
As another example, let’s combine the Vessels and Events APIs to get fishing events for a list of 20 USA-flagged trawlers:
# Download the list of USA trawlers
usa_trawlers <- get_vessel_info(
where = "flag='USA' AND geartypes='TRAWLERS'",
search_type = "search",
key = key
)
# Pass the vector of vessel ids to Events API
usa_trawler_ids <- usa_trawlers$selfReportedInfo$vesselId[1:20]
Note:
get_event()
can receive up to 20 vessel ids at a time
Now get the list of fishing events for these trawlers in January, 2020:
get_event(event_type = 'FISHING',
vessels = usa_trawler_ids,
start_date = "2020-01-01",
end_date = "2020-02-01",

The get_raster()

The get_region_id()
function also works in reverse. If a region id is
passed as a numeric
to the function as the region_name
, the
corresponding region label or iso3 code can be returned. This is
especially useful when events are returned with regions.

For API performance reasons, the get_raster()
function restricts
individual queries to a single year of data. However, even with this
restriction, it is possible for API request to time out before it
completes. When this occurs, the initial get_raster()
call will return
an HTTP 524 error, and subsequent API requests using any gfwr
get_
function will return an HTTP 429 error until the original request
completes:
Error in
httr2::req_perform()
: ! HTTP 429 Too Many Requests. • Your application token is not currently enabled to perform more than one concurrent report. If you need to generate more than one report concurrently, contact us at apis@globalfishingwatch.org
Although no data was received, the request is still being processed by
the APIs and will become available when it completes. To account for
this, gfwr
includes the get_last_report()
function, which lets users
request the results of their last API request with get_raster()
.
The get_last_report()
function will tell you if the APIs are still
processing your request and will download the results if the request has
finished successfully. You will receive an error message if the request
finished but resulted in an error or if it’s been >30 minutes since the
last report was generated using get_raster()
. For more information,
see the Get last report generated
endpoint
documentation on the GFW API page.
