A set of zones based on dissolving cc_grid for differentiating position wrt
the shore (sta_shore: "nearshore" or "offshore") and station patterns (
sta_pattern: "standard", "extended" or "historical").
Format
A sf spatial feature set with 6 rows x 9 columns:
- zone_key
unique zone key of the form
"{sta_pattern}-{sta_shore}"- sta_pattern
the CalCOFI station pattern; one of: "standard", "extended" or "historical"
- sta_shore
the position wrt shore; one of: "nearshore" or "offshore"
- sta_dpos
the difference in position: 5 (nearshore), 10 (offshore) or 20 (historical)
- sta_lin_min
the minimum value of dissolved
sta_linfromcc_grid- sta_lin_max
the maximum value of dissolved
sta_linfromcc_grid- sta_pos_min
the minimum value of dissolved
sta_posfromcc_grid- sta_pos_max
the maximum value of dissolved
sta_posfromcc_grid- geom
geometry of dissolved zone from
cc_gridwith latitude and longitude in decimal degree geographic coordinates (EPSG:4326)
