add_water: add_water

Description

Adds a layer of water to a map.

Usage

add_water(hillshade, watermap, color = "imhof1")

Arguments

hillshade

A three-dimensional RGB array.

watermap

Matrix indicating whether water was detected at that point. 1 indicates water, 0 indicates no water.

color

Default `imhof1`. The water fill color. A hexcode or recognized color string. Also includes built-in colors to match the palettes included in sphere_shade: (`imhof1`,`imhof2`,`imhof3`,`imhof4`, `desert`, `bw`, and `unicorn`).

Examples

# NOT RUN {
library(magrittr)
#Here we even out a portion of the volcano dataset to simulate water:
island_volcano = volcano
island_volcano[island_volcano < mean(island_volcano)] = mean(island_volcano)

#Setting a minimum area avoids classifying small flat areas as water:
island_volcano %>%
 sphere_shade(texture="imhof3") %>%
 add_water(detect_water(island_volcano, min_area = 400),color="imhof3") %>%
 plot_map()
# }
