create_grid {RiskMap}

Create Grid of Points Within Shapefile

Description

Generates a grid of points within a given shapefile. The grid points are created based on a specified spatial resolution.

Usage

create_grid(shp, spat_res, grid_crs = NULL)

Arguments

shp

An object of class 'sf' representing the shapefile within which the grid of points will be created.

spat_res

Numeric value specifying the spatial resolution in kilometers for the grid.

grid_crs

Coordinate reference system for the grid. If NULL, the CRS of 'shp' is used. The shapefile 'shp' will be transformed to this CRS if specified.

Details

This function creates a grid of points within the boundaries of the provided shapefile ('shp'). The grid points are generated using the specified spatial resolution ('spat_res'). If a coordinate reference system ('grid_crs') is provided, the shapefile is transformed to this CRS before creating the grid.

Value

An 'sf' object containing the generated grid points within the shapefile.

Examples

library(sf)

# Example shapefile data
nc <- st_read(system.file("shape/nc.shp", package="sf"))

# Create grid with 10 km spatial resolution
grid <- create_grid(nc, spat_res = 10)

# Plot the grid
plot(st_geometry(nc))
plot(grid, add = TRUE, col = 'red')
