summarize_locations: summarize_locations

In Maritimes/Mar.bycatch: Facilitates Extraction and Linking of Commercial and Observed Fisheries Data for the Maritimes

summarize_locations

Description

This function takes the results from get_marfis() and get_isdb() and produces a table showing the how the proportion of observed data varies across areas. Results for NAFO areas are always provided, as these areas are stored in both MARFIS and ISDB databases. If a custom area is specified (via the areaFile parameter), the sets from both the MARFIS and ISDB data are analyzed for that area too (as a separate dataframe).

Usage

summarize_locations(get_isdb = NULL, get_marfis = NULL, ...)

Arguments

get_isdb	default is NULL. This is the list output by the Mar.fleets::get_isdb() function - it contains dataframes of both the trip and set information from ISDB related to the specified fleet
get_marfis	default is NULL. This is the list output by the Mar.fleets::get_marfis() function - it contains dataframes of both the trip and set information from MARFIS related to the specified fleet
...	other arguments passed to methods

Value

returns a list with 1 or 2 dataframes. These dataframes indicate how much of the fishing activity took place in various areas. Values are categorized as both "*_reported" and "*_calculated". "Reported" values are based on the NAFO information stored in MARFIS and ISDB. These are available for MARFIS trips, MARFIS sets, and ISDB sets. "Calculated" values are based on the coordinates associated with the data, and are only available for the MARFIS and ISDB sets (not trips).

• NAFO = This is always provided.

• <Mar.data::object_name> = This is only provided when a specific "areaFile" is provided as a paramater.

Note

• _SETS Coordinates for MARFIS_* data comes from the db table "LOG_EFRT_STD_INFO" (preferring *_ENT coordinates over *_DET ), and coordinates for ISDB_* data come from "ISSETPROFILE" - using the first non-null pair found while checking from P1-P4 in order.

• Weird Coordinates In addition to falling within a known area, data can also be categorized any of the following:

  • <missing coord> These are missing values for with LAT or LONG (or both)

  • <impossible coord> These have latitudes or longitudes outside of the acceptable ranges of 90 - -90 and 180 - -180, respectively

  • <on boundary line> These coordinates fall exactly on a boundary line dividing 2 areas

  • <LAND> For NAFO areas, points that fall on land (according to Mar.data::NAFOSubunitsLnd_sf) are indicated as such

  • <outside known areas> These are points that fall outside any of the known polygons for the specified area. For non_NAFO areas, this can include land.
