gfwr: Access data from Global Fishing Watch APIs

DOI Project Status: Active - The project has reached a stable, usable state and is being actively developed. Licence :registry status badge

Important
This version of gfwr gives access to Global Fishing Watch API version 3. Starting April 30th, 2024, this is the official API version. For latest API releases, please check our API release notes

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:

  • Vessels API: vessel search and identity based on AIS self reported data and public registry information
  • Events API: encounters, loitering, port visits, AIS-disabling events and fishing events based on AIS data
  • Gridded fishing effort (4Wings API): apparent fishing effort based on AIS data

Note: See the Terms of Use page for GFW APIs for information on our API licenses and rate limits.

Installation

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)

Authorization

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 use key = gfw_auth() by default.

Vessels API

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”

Examples

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'"), use parameter where instead of query:

get_vessel_info(where = "shipname LIKE '%GABU REEFE%' OR imo = '8300949'",
                search_type = "search",
                key = key)

  • The id search allows the user to specify a vector of vesselIds

Note: 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 using get_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",
                key = key)

This is useful especially because a vessel can have different vesselIds in time.

Check the function documentation for examples with the other function arguments and our dedicated vignette for more information about vessel identity markers and the outputs retrieved.

Events API

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 about events in our caveat documentation.

Events in a given time range

You can get events in a given date range. By not specifying vessels, the response will return results for all vessels.

get_event(event_type = 'ENCOUNTER',
          start_date = "2020-01-01",
          end_date = "2020-01-02",

Note: We do not recommend trying too large downloads, such as all encounters for all vessels over a long period of time. This will possibly return time out (524) errors. Our API team is working on a bulk download solution for the future.

Events in a specific area

You can provide a polygon in sf format or the region code (such as an EEZ code) to filter the raster. Check the function documentation for more information about parameters region and region_source

Events for specific vessels

To extract events for specific vessels, the Events API needs vesselId as input, so you always need to use get_vessel_info() first to extract vesselId from $selfReportedInfo in the response.

Single vessel events

vessel_info <- get_vessel_info(query = 224224000, key = key)
#> 1 total vessels

#> # A tibble: 2 × 14

The results show this vessel’s story is grouped in two vesselIds.

To get a list of port visits for that vessel, you can use a single vesselId of your interest:

id <- vessel_info$selfReportedInfo$vesselId
id
#> [1] "6632c9eb8-8009-abdb-baf9-b67d65f20510"
#> [2] "3c99c326d-dd2e-175d-626f-a3c488a4342b"

get_event(event_type = 'PORT_VISIT',
          vessels = id[1],
          confidences = 4,
          key = key
          )

get_event(event_type = 'PORT_VISIT',

Note: Try narrowing your search using start_date and end_date if the request is too large and returns a time out error (524)

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, the id field for encounter events includes an additional suffix (1 or 2) separated by a period. The vessel field will also contain different information specific to each vessel.

Multiple vessel events

As another example, let’s combine the Vessels and Events APIs to get fishing events for a list of 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,
  quiet = TRUE # quiet = FALSE if you want an estimate progress of the download
)

This list returns 6592 vesselIds belonging to 4144 vessels.

Fishing effort API

The get_raster() function gets a raster from the 4Wings API and converts the response to a data frame. In order to use it, you should specify:

  • The spatial resolution, which can be LOW (0.1 degree) or HIGH (0.01 degree)
  • The temporal resolution, which can be HOURLY, DAILY, MONTHLY, YEARLY or ENTIRE.
  • The variable to group by: FLAG, GEARTYPE, FLAGANDGEARTYPE, MMSI or VESSEL_ID
  • The date range note: this must be 366 days or less
  • The region polygon in sf format or the region code (such as an EEZ code) to filter the raster
  • The source for the specified region. Currently, EEZ, MPA, RFMO or USER_SHAPEFILE (for sf shapefiles).

Examples

We added a sample shapefile inside gfwr to show how 'USER_SHAPEFILE' works:

data("test_shape")

get_raster(
  spatial_resolution = 'LOW',
  temporal_resolution = 'YEARLY',
  group_by = 'FLAG',
  start_date = '2021-01-01',
  end_date = '2021-02-01',
  region = test_shape,
  region_source = 'USER_SHAPEFILE',
  key = key

If you want raster data from a particular EEZ, you can use the get_region_id() function to get the EEZ id, and enter that code in the region argument of get_raster() instead of the region shapefile (ensuring you specify the region_source as 'EEZ':

# use EEZ function to get EEZ code of Cote d'Ivoire
code_eez <- get_region_id(region_name = 'CIV', region_source = 'EEZ', key = key)

get_raster(spatial_resolution = 'LOW',

It is also possible to filter rasters to one of the five regional fisheries management organizations (RFMO) that manage tuna and tuna-like species. These include "ICCAT", "IATTC","IOTC", "CCSBT" and "WCPFC".

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.

# using same example as above
get_event(event_type = 'FISHING',
          vessels = ten_usa_trawlers$vesselId,
          start_date = "2020-01-01",

          key = key

When your API request times out

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.
