Generate a rectangular polygon from extent
Usage
ext2poly(extent = NULL, output_class = c("sf", "terra"), crs = "EPSG:4326")Arguments
- extent
input extent. A numeric vector with xmin/xmax/ymin/ymax, sf::st_bbox or terra::ext outputs.
- output_class
character(1). Class of the output polygon. One of
"sf"or"terra"- crs
character(1). Coordinate reference system definition.
