ICESrectangles: ICES rectangles

In StoXProject/RstoxFDA: Fisheries Dependent Analysis with RstoX

ICES rectangles

Description

Definitions for ICES rectangles. ICES rectangles are defined by grids made up from integer longitudes, integer latitudes, and a bisection between each pair of latitudes. They derive their name from being rectangular in mercator projection.

Usage

data(ICESrectangles)

Format

SpatialPolygonsDataFrame with rectange names identified in the column 'StratumName'. See StratumPolygon.

Details

The data contains the following columns with rows for each rectangle:

ICESNAME

name of the rectangle in standard ICES notation

SOUTH

southern border of rectangle (latitude)

WEST

western border of rectangle (longitude)

NORTH

northern border of rectangle (latitdue)

EAST

eastern border of rectangle (longitude)

Area_Full

Code for full ICES area, including the FAO area code (27).

Area_27

Code for full ICES area, excluding the FAO area code (27).

The data also contains columns for the individul components of the full ICES area code: <Major_FA>.<SubArea>.<Division>.<SubDivision>.<Unit>

Polygons are derived from shapefiles provided by ICES web-portals.

Polygons are defined in WGS84 coordinates (unprojected).

Examples

 # plot statistical rectangles in 27.3.a
 rect27.3.a <- RstoxFDA::ICESrectangles[
    RstoxFDA::ICESrectangles$SubArea==3 & 
    RstoxFDA::ICESrectangles$Division=="a",]
    
 RstoxFDA::plotArea(areaDef = rect27.3.a)
