create_ignition_polygon: Create an ignition point shapefile

In mbedward/farsitebatch: Run FARSITE simulations in batch mode

Description

FARSITE requires a polygon shapefile for ignition location. This function takes the coordinates for a point, creates a square polygon around it of specified width, and saves this as a shapefile.

Usage

create_ignition_polygon(path, xy, width, crs = sf::NA_crs_)

Arguments

path	Path for the output shapefile.
xy	Two element vector with X and Y ordinates of ignition location.
width	Width of the polygon to create.
crs	Optional coordinate reference sytem (e.g. EPSG integer code).

Value

A spatial data frame (sf object) with the ignition polygon.
