This function creates a rectangle of specified width and height, centered on a given point.

Usage

st_create_rectangle(center, xsize, ysize, crs = 2193)

Arguments

center: A numeric vector of length 2 specifying the x and y coordinates of the center of the rectangle (e.g., c(x, y)).
xsize: Numeric, the total width of the rectangle (in the same units as the coordinate reference system, typically meters).
ysize: Numeric, the total height of the rectangle (in the same units as the coordinate reference system, typically meters).
crs: Numeric, the coordinate reference system (CRS) of the output geometry. Default is EPSG:2193 (NZTM2000).

Value

An sf object representing the rectangle polygon.

Examples

# Example usage: Create a rectangle with width 1000 meters and height 500 meters centered at (1577107, 5173732) in NZTM2000
rectangle_sf <- st_create_rectangle(center = c(1577107, 5173732), xsize = 1000, ysize = 500)

# Plot the rectangle
plot(rectangle_sf)
} # }
