Geospatial pacea grid - BC coastline grid template with depth data

Description

TODO Needs updating, plus vignette, when we have time; see Issue 48. A simple features object of the grid used for interpolation of British Columbia continental margin (BCCM) model. The grid is divided into two regions with differing resolutions: a higher resolution inshore 2km x 2km grid and lower resolution offshore 6km x 6km grid. The boundary between the two regions is created using the 200m isobath along the continental shelf.

Usage

grid26_depth

Format

A simple features dataframe, with columns 'x' (the geometry), 'mean_depth', 'min_depth', and 'max_depth'. Depths are negative because there are a few positive ones (above sea level) along the coastlines, which we will look at in more detail. NB we will make the depths all positive at some point as that's more logical (well, except for donig physical oceanography models).

Details

TODOGrid cells were removed where the overlapped land using the 'bc_coast' shapefile in pacea. The grid only covers the Canadian Pacific EEZ region with a 10km buffer.

Source

Generated from running 'data-raw/depth/depth.R'.

Examples

## Not run: 
head(grid26_depth)
plot(grid26_depth)  # not great as it shows the grid, this is better:
grid26_depth %>%
 ggplot(.) +
 geom_sf(aes(fill=mean_depth),
         colour=NA)

# convert to sf points object - from gri26 help TODO
#library(sf)
#grid26_points <- st_centroid(grid26)
#
## End(Not run)
